Tuff Coat EPA Stoving Varnish is Single component systems designed to cure at elevated temperature. It consists modified Epoxy - Amino System.
RANGE OF APPLICATION
Besides its excellent anti corrosive properties this Varnish gives Good Gloss, Hard Film with required flexibility. This Varnish can be applied directly on MS, Stainless Steel, Aluminum and also on Epoxy / PU /CR painted surfaces for extra protection. This makes the system useful for Protective Coating. Resistance to Oils, Alcohol, Water, Salty weather, Abrasion & heat makes the system ideal for chemical Industries, Valves and Various machineries. It is also recommended on electroplated components to resist the weather effect & degradation of plating /coating. It helps to avoid Erosion / Corrosion of stainless steel & other metals.
