The first truly water-based, low VOC, and easy-to-use coating offering outstanding corrosion resistance of up to 3,000 salt spray hours.
The fasteners below were pretreated with electro plated zinc and applied in accordance with ASTM-B633 Class SC1 including a deposit of 0.3 mils. To improve adhesion of the topcoat, zinc phosphate was applied. These fasteners exhibited less than 15% red rust after 3,000 salt spray hours.
Teflon™ coatings have been improved to provide environmentally friendly fluoropolymer systems that combat the most corrosive environments. One of the newest Teflon™ offerings is a truly water-based one coat system that provide excellent corrosion resistance. These coatings are specifically designed for coating off shore, chemical processing, and water treatment fasteners on substrates such as carbon steel, stainless steel, and aluminum.
