DriPHOS Metal Treatment

A new solution to the problems caused by conventional metal cleaning and pretreatment systems in product finishing.

EnviroTech Surface Technologies looks at some of the traditional problems associated with solvent and aqueous degreasing prior to painting and powder coating and explains how the DriPHOS® metal cleaning option can offer a viable alternative to conventional processes. The DriPHOS® surface treatment process has evolved to produce a revolution in metal finishing.


DriPHOS ® the start of a great finish
Traditionally jobbing painters and/or manufacturers of parts who have to subsequently degrease and then paint or powder coat have had the same problems that they have learnt to live with. These include: reject rates of between 3-­8% after painting; residues of particulate that require further manual wiping after degreasing and prior to painting; paint schemes lifting or blistering; corrosion forming under painted areas; parts slowing down the production because the drying oven takes an excessively long time to dry sufficiently; or parts simply going rusty during the dwell time between cleaning and subsequent painting. Finally, when using conventional solvents, long dwell times whilst the components cool down to a temperature that can take the paint prior to curing in the oven. More recently, classification of Trichloroethylene has also caused concern.

Trichloroethylene a known human carcinogen

Filed under: News — admin @ 4:35 pm

Trichloroethylene formally listed as a “Known Human Carcinogen”.

Replace Trichloroethylene

After many years of being listed as a possible or probable human carcinogen, the widely used solvent trichloroethylene (TCE) has now been listed by the National Toxicology Program (NTP) of the U.S. Department of Health and Human Services as a “known human carcinogen.” Ref; NTP’s 14th Report on Carcinogens (November 3, 2016).

Trichloroethylene is widely used in manufacturing industries as a vapour degreasing solvent but its principal uses are as an intermediate raw material in hydrofluorocarbon chemical manufacture. In the light of a number of human studies showing a causal connection between TCE exposure and an increased risk of kidney cancer, NTP re-evaluated and ultimately reclassified TCE. In addition to cancer risk, other problems that have been attributed to TCE exposure include immunotoxicity, neurotoxicity, reproductive toxicity and developmental toxicity, such as potential fetal cardiac defects.

As a known carcinogen exposure to TCE is highly regulated already in the European Union. From April 2016 its use has required authorisation for specified applications.

The ban on the use of TCE for vapour degreasing, a very widely used cleaning process, causes many problems in the engineering and manufacturing industries where oil and soils need to be removed between stages in the production processes and on finished products. The use of alternative water based cleaners are inconvenient and increase process times and costs.

A safer alternative, EnSolv is available as an established “drop in” replacement for TCE often using existing  vapour degreasing  equipment. For more information on conversion, help or advice from EnviroTech Europe Specialist team go to www.vapour-degreasing.com.

DriPHOS Metal Treatment

DriPHOS Metal Cleaning – One tank cleaning and surface treatment revolutionises metal finishing.

DriPHOS TLT is a new solvent based, single tank metal cleaning and pre-treatment process developed by EnviroTech Surface Technologies which uses Thin Layer Technology to produce consistent high quality finishes.  Completely different to conventional pre-treatment processes it uses only one tank to clean, pre-treat, rinse and dry components which emerge warm to touch and with a crystalline coating on the surface which improves adhesion and protects metals against in house rusting or corrosion.    DriPHOS metal cleaning can replace current aqueous multi-tank systems reducing energy usage by at least 50%, reducing process times to 5 minute cycles, increasing throughput and uses 60%  less space releasing floor area for more productive work.

This new system will be familiar to users of the vapour degreasing process on which it is based but with the added benefit of surface pre-treatment in one tank. The  footprint of the equipment  will be the same as a vapour degreasing tank processing similar sized components.  DriPHOS TLT uses a proprietary blend of compounds in a stable low boiling point solvent carrier to dissolve the active chemicals which produce the protective crystalline structure on the metal surface.

The DriPHOS TLT metal pre-treatment process cleans surfaces to a very  high  standard   and produces a nano-thickness protective crystalline primer coating which is part of the metal surface. The coatings are extremely flexible with a very large surface area to improve the adhesion of subsequent coatings such as paint or powder coatings which are then more resistant to impact damage or scratches.

DriPHOS Metal Treatment

DriPHOS Crystal Structure magnified x 1000

The Nano thickness DriPHOS TLT crystalline coating does not change dimensions of components but flexes with the metal preventing delamination of coating films when knocked or bent which greatly increases corrosion protection compared to the random amorphous coating of conventional aqueous pre-treatments.

The very large increase in surface area is due to the unique “fish scale” structure of overlapping crystals growing from and an integral part of the metal surface. This produces more keying area priming the metal for subsequent paint, powder and other finishes to improve the adhesion of these coatings which are then more resistant to impact damage or scratches.

The DriPHOS TLT formulation has minimal environmental impact the blend of non- flammable compounds and solvents are short lived in the atmosphere and do not pose a significant potential for global warming or have an adverse effect on the ozone layer or accumulate in soils or water. Operating temperature is only 40C and no drying is required after treatment so energy usage for the whole process is very low, reducing costs and production of CO2.

Simple, sophisticated technology reduces costs while improving quality. Processed components are warm to the touch and instantly available for further fabrication, assembly or finishing. In industries such domestic and office furniture, point of sale and retail displays where small batches of different colours are needed. Stored parts will not rust or corrode for long periods under normal conditions allowing larger more cost effective batches of components to be produced.

Operators use the process safely with equipment designed to  ensure  minimal emissions or exposure to solvent.  The DRiPHOS TLT process is   simple   to   maintain   with ongoing technical support from EnviroTech partners, product specialists Fraser Technologies. Regular testing of the liquids ensures trouble free operations. Operators are trained on site to maintain the bath using the test  kits supplied and most importantly the quality control can be visually monitored instantly by the colour change on the metal surface. Iridescent blue through, gold to red instantly shows the level of crystalline coating which ensures management have complete assurance of process integrity. Price includes sample reports with regular visits by product specialists to guarantee the very highest quality of pre-treatment and final finish on products with safety for people and the environment.

Information or advice on the use of DriPHOS TLT or to arrange validation trials at the new test centre or visits by product specialists appointments can be made by phone or through the website www.metal-treatment.com.

CORR-EX LCP-177 Lubricant And Corrosion Inhibitor

Filed under: News — Tags: , , — admin @ 4:27 pm

How CORR-EX LCP-177 protective lubricant prevents seizures of automatic handling systems in the harsh conditions of Industrial cleaning systems..

Specialist cleaning equipment manufacturer C&C Hydrosonics a division of U.S giant Crest Ultrasonics have solved a problem with seizures occurring the on x-y axis linear tracks on their automatic handling systems fitted to multi tank cleaning systems both aqueous and solvent based.

The automatic handling systems are programmed to process baskets or jigs through a cleaning cycle transferring between tanks, lowering and raising work from the liquids. The motorised carriages use nylon wheels running on case hardened mild steel tracks (stainless steel is not available) which corrode in the chemical atmospheres in the machine canopies.
The corrosion prevents smooth running with wheels seizing and binding on the tracks. The vibration can cause components to be shaken from jigs or in extreme cases the carriage will stall requiring intervention by service engineers to remove corrosion and re-lubricate tracks with oil. This is a temporary measure as the oil is quickly removed by the solvents and water based cleaning solutions with corrosion recurring in a short time.


CORR-EX LCP-177 from EnviroTech Surface Technologies is an innovative dry lubricant formulation  with protective properties which forms a self-healing film applied from an aerosol. The inorganic lubricant is unaffected by water and acts a barrier against rusting and corrosion. Extensive Trials by C&C Hydrosonics over a six month period with both solvent and water based systems demonstrated that CORR-EX LCP-177 offered a simple solution to the problem with no seizures during the trial period. Previously maintenance every six weeks was needed, now an aerosol spray of CORR-EX LCP-177 is used only during service  visits as a routine lubrication  and applied during production of the handling system.

Lee Casey Managing Director of C&C is delighted with the cost savings on reduced service and maintenance calls using CORR-EX LCP-177 but is even more pleased that the inconvenience to customers has been eliminated. Use of CORR-EX LCP-177  has now been extended worldwide on Crest automated handling systems.

CORR-EX LCP-177 is available from EnviroTech Europe Ltd and distributors worldwide.

The only realistic “drop in” replacement for TRIKE.

Filed under: News — admin @ 4:39 pm

Replace Trichloroethylene

Why EnSolv is the only realistic “drop in” replacement for TRIKE as a Vapour Degreasing Solvent.

Syd Treacher, a Surface Cleaning Consultant discusses the current controversy regarding replacements for trichloroethylene, the most commonly used vapour degreasing solvent, which was to be phased out of use in industrial applications in April  2016.

This article was prompted while reading an article where the author claimed that a grade of fluorocarbon solvent was a “drop in” replacement for TRIKE (trichloroethylene) and n- propyl bromide. This statement is not true for the majority of applications for which trichloroethylene is used – vapour degreasing or more correctly condensation cleaning.

As a consultant in surface cleaning technology I have studied the options available and come to the conclusion that the stabilised n-propyl bromide (nPB) sold in the UK under the brand name EnSolv® is the ONLY realistic “drop in” replacement for trichloroethylene when used for vapour degreasing. It is on average up to 50% cheaper than fluorocarbon formulations being proposed as alternatives.

From my evaluation it is clear current users of EnSolv® can continue to use the solvent and equipment or if still if using TRIKE you can make the change to EnSolv® in a day. A decision has to be made quickly as the “sunset date” after which TRIKE will not be available  for industrial use without authorisation in the EU was April 2016 but you can substitute with only minor changes to control settings on equipment. The legislation regarding the use of nPB may change in the future but if this happens you will have at least 3 years to decide on the alternative so the savings in solvent costs over this period will be considerable compared to alternative materials.    Read  the full article here..

Degreasing And Cleaning – Key Questions To Ask


There can be no doubt that manufacturers of metal components have remained keenly interested in the advantages to be found in process cleaning, while being confused by the amount of misinformation that seems presented to them.


There can only be two reasons for this. These is an intention to mislead or simply a lack of understanding of the subject.

In any event, the user needs to take time to match what is said to what is fact. Too often companies generalise on the basis that they are not keen for users to look deeply at the subject, yet this is vital if good decisions are to be made.

In the end, the final judgement of the user is what matters but how many people express frustration at some of the suppliers they have met who spent more time criticising a proven product rather than validating their own.

Too often, suppliers are advising what not to do rather than dealing with what really works. This is negative selling and appears on the increase as the market shrinks, regulation gets tighter and independent specialists are more limited in numbers.

Recent history suggests that larger suppliers rely on their size to justify their competence when in fact the really satisfied customers are saying smaller companies with real specialists provided the best solutions.

No one can argue against the fact that the popular choice for metal cleaning and degreasing is still vapour degreasing. This is confirmed by the companies involved in making machinery for degreasing. The order books are heavily stacked in favour of vapour degreasing. If there is one slight disadvantage currently, lead times are often 20 weeks to delivery of machines.

It is clear though that these highly cost-effective systems, which use very little solvent, are likely to remain the first choice for some considerable time.

Arguments related to the Solvent Emissions Directive carry little weight with modern machines as they are so well engineered that they are compliant with regulatory requirements. If there is one common request made by users it remains that they wish there was a single company capable of offering the total solution, e.g. both their own product and machinery together. This would shorten the circle and place more pressure on the supplier to be responsible for promises made.

Most machinery companies work with a multitude of chemistry suppliers, since they want the maximum sale of machines, but should disputes arise this can be a protracted problem as it’s easy to blame someone else for the issues involved.

Much is said about vacuum and hermetically sealed systems being the best solution. They are certainly the most expensive. Speak to an independent specialist to ensure you know the limits of these machines and the cost benefits of alternative designs.

Suppliers who claim aqueous systems are superior need to ensure they advise the user that more energy, more space, longer cleaning cycles more risk of residues and waste disposal issues should be taken into account. Global warming is an issue for all of us so factor in the amount of energy required for heating and drying. To accept that water is safer or better, needs to be well argued. Never forget that water-based cleaning solutions need changing regularly and the oils and metals produced by these processes are waste and needs correct and very expensive disposal.

When considering vapour degreasing it will often be suggested that product transfer systems attached to the existing open-topped machine bring a number of benefits. For handling benefits it is true but never doubt they will not contribute to reducing your consumption, so will do nothing for emission targets.

The best way forward is to make a supplier talk to you about their own product. Beware of those who distract you from this. If a claim is made that seems suspect, ask for the claims to be made in writing. Transparency is a vital ingredient in any relationship with your supplier.

The target audience for most suppliers are those using the carcinogen Trichloroethylene. This is now banned for general use and requires specific authorisation for use in cleaning applications. Do your research, set the questions and insist on the evidence for the arguments put forward. Protecting your business, your staff and the community around you gives a sound basis to ensure a real assessment.

Replace Banned Trichloroethylene

Filed under: News — admin @ 11:44 am

Trichloroethylene is banned by the EU and will not be available after 21 April 2016.

Still using trichloroethylene for vapour degreasing?

The final EU “Sunset Date” is on 21 April 2016 when use of this solvent will be illegal without specific authorisation and unless very expensive fully enclosed vacuum equipment is installed. Exemptions are unlikely if an alternative is available.

Replace Trichloroethylene

Replace Trike now with EnSolv  – the simple “drop in” replacement for Trichloroethylene.

EnSolv is stable, economical, a superb vapour degreaser operating at 70˚C which means less energy, easier handling, faster throughput and lower usage. Very safe for operators, EnSolv is a simple replacement using existing equipment which needs no new skills – resetting the thermostats is all that’s necessary.

Alternative solvents based on fluorocarbons are available but are not “drop in” replacements and are very expensive. The equipment needed to use these materials is not available off the shelf with equipment manufacturers quoting months for delivery.

EnSolv is supplied and serviced by an experienced, expert group of distributors, fully trained to carry out inspections of your equipment and processes and advise and support the changeover which can be done in hours.

A visit to your works by a member of our Trichloroethylene Substitution Team to survey, report and process samples to validate cleaning and compatibility with soils, oils and metals of construction is completely free and without obligation. You are also welcome to personally visit our Technical Centre, close to Stansted Airport, to test samples yourself and discuss your needs with our experts.

An alternative to vapour degreasing is water based cleaning systems. EnviroTech Surface Technologies can supply suitable materials for appropriate needs where the next part of the process, anodising or electroplating are water based or where use of solvent is not compatible with the materials used in manufacturing of components. But the installation costs, use of multi tanks taking up space which could be used for more productive and profitable uses, disposal of water and energy costs for drying are not economical when compared to simple substitution, by EnSolv using existing equipment.

We have the all facts for you to consider before you make the commitment. Call on the number below or go to our product website www.ensolv-europe.com and book a free visit by one of the experts from our Trichloroethylene Substitution Team or arrange an appointment to meet us at our Technical Centre.
