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.
