Product Features
Excellent adhesion to substrates including stainless steel, aluminum alloy, galvanized steel and aluminum plating, with pull-off adhesion reaching 4MPa.
The coating is corrosion-resistant and can effectively resist acid, alkali, salt, seawater and other media corrosion.
The thick-coat application is less prone to sagging, and it is more capable of covering up than traditional epoxy primer products. It also helps reduce the cost of topcoat.
