SuperCORR A Protects From Corrosion


Super
CORR
A maintains performance of thinner gold plating used on electrical contacts to protect from corrosion.

SuperCORR A ultra-thin film dry lubricant prevents galling corrosion caused by vibration on printed circuit leads and connectors.

Advances in gold plating technology allows manufacturers to reduce plating thickness on the substrate metal used for contacts in electrical connectors.

The thickness of gold plating is decreasing and becoming thinner over time which reduces manufacturing costs as gold becomes increasingly expensive.

Reducing thickness of gold plating however can result in failures caused by corrosion. Minute irregularities in the surface of the connector’s base metal leads to irregular or uneven wear causing the “high spots” on the contacts to wear through the gold plating. Using SuperCORR A aerosols prevents or delays corrosion and subsequent failures.

TESTING SuperCORR A IN CONNECTOR “RUB TEST”.

SuperCORR A is a lubricant containing corrosion preventive compounds, and as is the case with all lubricants they will be worn off over time. A manufacturer of connectors tested SuperCORR A to see what the “life” of the lubricant was in a “rub test”. The typical test is 20,000 cycles, i.e. unplug, plug in is one cycle. The test results demonstrated that after 20,000 cycles there were no failures.

It was decided to take it one more step and run the same tests for 200,000 cycles. The results again showed no indications of galling or scoring on the USB connectors. The USB connector looked and tested as good as new.

MILITARY USES OF SuperCORR A

As it is compliant with Mil-L-87177A specifications SuperCORR A is used by the U.S. Air Force to protect the intricate workings of the F-16 Fighter Jet and by the U.S. Navy on the P 3 Orion electronic surveillance aircraft. Savings for the U.S. government is estimated at $50 million per year. Commercial Aviation aircraft manufacturers recommend it for electrical and close mechanical application, especially where flights are in salt fog or high humidity.

Containing extremely long-lasting, proprietary anti-corrosive inhibitors SuperCORR A provides a superior lubrication coefficient and protects components against moisture, wear, general and fretting corrosion, surface static electricity, corona, and other electro migration problems. The ultra-thin, non-flammable lubricant film is only 7 microns (0.0007 inch) thick and is formulated without sulphates, chlorides or halogens to meet the EU RoHS directive. It is unexcelled in preventing deterioration and contamination on all surfaces of electronic equipment.

SuperCORR A Cleans And Protects Electrical Connections

SuperCORR A aerosols clean and protect electrical connections on mobile generators during aircraft ground services.

Clean And Protect Electrical Connections


Super
CORR
A aerosols clean and protect electrical connections on mobile generators during aircraft ground services.

Aircraft ground services operate in extreme and often hostile weather environments. Mobile generators connect and disconnect many times a day often in extreme weather conditions. Each disconnection can allow dust or rain water onto the electrical connections. SuperCORR A aerosol cleans, dries, lubricates and protects electrical connections on site ensuring uninterrupted service.  

Mobile generators are used throughout the world by extraction industries and manufacturing plants in remote and hostile locations for essential power production. Dusty and wet environments in deserts, mines, grinding mills, pulp and paper mills and on land or sea drilling rigs for gas and oil production. Generators powering aircraft services while stationary connect and disconnect many times a day in extreme conditions. The flexing of the connecting cables allows sufficient movement between the metal surfaces of the connecting pins to produce fretting corrosion which reduces, interrupts or produces failures in supply.

SuperCORR A is an aerosol lubricant containing corrosion preventive compounds, and, as is the case with all lubricants, they can be worn off over time. A manufacturer of connectors tested SuperCORR A  to see what the “life” of the lubricant was in a “rub test”. The typical test is 20,000 cycles, i.e. unplug, plug in is one cycle. The test results demonstrated that after 20,000 cycles there were no failures. It was decided to take it one more step and run the same tests for 200,000 cycles. The results again showed no indications of galling or scoring on the connectors at all. The connector looked and tested as good as new. This test was run under clean conditions in a laboratory but demonstrates the effectiveness of the protective lubricant in SuperCORR A . As it meets Mil-DLT-87177B specifications it is used by the U.S. Air Force to protect the intricate workings of the F-16 and F-15 fighter jets and by the U.S. Navy on the P 3 Orion electronic surveillance aircraft. Savings for the U.S. government is estimated at $50 million per year. Commercial Aviation aircraft manufacturers recommend it for avionics and electrical switches and connectors and close mechanical application, especially where flights are in salt fog or high humidity.

Containing extremely long-lasting, proprietary anti-corrosive inhibitors, SuperCORR A provides a superior lubrication coefficient and protects components against moisture, wear, general and fretting corrosion, surface static electricity, corona, and other electro migration problems. The super thin non-flammable lubricant film is only 7 microns (0.0007 inch) thick and is formulated without sulphates, chlorides or halogens to meet the RoHS directive. It is unexcelled in preventing deterioration and contamination on all surfaces of electronic equipment.

Very fast drying environmentally acceptable solvents are used as carriers and propellants which will not affect most plastics, substrates, metals or other materials used in connector manufacture. The aerosols are supplied with probes which allow access to pins and connector tubes where the low surface tension repels water, dirt dust and metal particles from blind holes and surfaces to produce thoroughly clean holes and surfaces before a second application applies the lubricant film. Reconnection to the supply with cleaned sections of the connector ensures reliable operation even in the most testing of environments. This easy maintenance from one can of SuperCORR A allows this essential task to be carried out in any conditions quickly, easily and securely.

Eco Friendly Industrial Solvent Cleaners

Clarea Solvent Cleaners

Eco Friendly Industrial Solvent Cleaners, Safe for Users and the Environment.

Cleaning solvents are used in many industries to remove dirt, oil, grease, or other contaminants from machined and fabricated metal, plastic and composite surfaces. Due consideration must be given to the effects on users and the environment.  Some of the benefits of using Clarea solvents for these applications are discussed in this article.

Solvents used for cleaning must be highly refined and leave no residues on drying. They have to be very effective in removal of oils and soils without causing damage or corrosion of the parts or components being cleaned and leave minimal residues which will be the result of process design. Cleaning to remove process oils and particles can use single or multitank spray washers or immersion tanks with ultrasonics or agitation depending on the volume of components and cleaning specifications. These vary widely from very demanding automotive and aerospace applications to less demanding applications where critical cleaning is not a requirement.

Pre-used parts or assemblies from the transportation, aerospace or manufacturing equipment sectors are often very heavily contaminated when removed from service but must be free of these oils, soils, grease, dirt and contaminants before handling to disassemble prior to refurbishing and rebuilding. Much of this work will be manual and the considerations for the safety of operators, hand wiping or brush cleaning is paramount. Provision of personal protection equipment (PPE) such as gloves, overalls, safety glasses and possibly masks must be carefully considered to be sure the PPEs are compatible with the solvents.

Among other considerations are the working space where the cleaning applications are to be carried out. Flammability versus drying time is always an issue. It is preferable to use a slower drying high flash point solvent in enclosed areas. Good ventilation with a high extraction rate of air will assist drying. In enclosed machines with automatic handling a positive extraction rate of air and heated and extracted final tank can lower process times. Flame proofing requirements and the insurance implications of the faster drying times of more volatile flammable solvents is often mitigated by the use of less volatile, lower VOC materials by design of machines and careful consideration of costs which these solvents offer in lower usage and longer tank life with much lower disposal costs of used materials.

The growing concerns regarding environmental and health hazards of the most commonly used chlorinated solvents for industrial degreasing and cleaning has led to the formulation by EnviroTech Europe of the Clarea range of safer cleaning solvents.

Clarea solvents can be used for spray or immersion cleaning for very heavy soiling or in multitank processes to meet the highest standards demanded for critical cleaning. They can be used as wipe or brush cleaners for large surface areas prior to painting or powder coating.

Why should you choose Clarea industrial cleaning solvents.

The solvents applied during production or finishing processes have a direct effect on the health of workers and the environment. Volatile organic compounds or VOCs are chemicals which vaporise at room temperatures. Traditional solvents used for cleaning have low boiling points and a high VOCs making them harmful to use and less eco-friendly Exposure to the VOC’s released by these cleaning agents must be controlled to prevent respiratory, allergic, and immune system complications for users. If your company uses industrial degreasing agents regularly, it is time to evaluate the implications of this choice.

Clarea is a less volatile alternative than conventional cleaners. Highly refined aliphatic hydrocarbons with minimal residues and tight vaporisation ranges are capable of providing the same results and can be substituted to create a safer, sustainable, eco-friendly workplace. The low odour, low flammability and low toxicity of Clarea solvents provides performance and operator and environmental acceptability using less material at lower costs. Multipurpose use can reduce the inventory of cleaning fluids stocked.

Clarea® HC40 for brush and hand wiping, air dries. Flash point 40℃.

Clarea® HC62  for dip cleaning with agitation or ultrasonics. Low evaporation. Non-flammable.
