Strongly Adhesive Epoxy Zinc Rich Primer for Anti-corrosion
PRODUCT DESCRIPTION
Epoxy Zinc Rich Primer is a two-component product based on epoxy resin, added with superfine zinc powder and polyamide curing agent. In accordance with the class 1, class2 and class 3 in HG/T3668-2009 type II, it is highly corrosion-resistant, highly anti-rust and has strong adhesion. Besides, it has the characteristics of small burn area during welding and cutting. As it is also oil, water and solvent resistant, it can be used with most anti-rust paints and finish coatings.This product is widely used on sandblasted steel surface. Matched with suitable coatings, its corruption-resistant ability can be improved.
Typical Uses:
It is highly recommended for steel pipes, storage tanks, steel structures, containers, etc.
