Molawan Abrasion Resist
Molawan Abrasion Resist is a Cost-Effective, Polyester Polyamide Pre-Painted Galvanized Steel Developed for Applications Under Frequent Abrasion. The paint is a Polyester Polyamide system, applied on a Galvanized substrate of Minimum 90 GSM zinc coating, with paint film thickness of 20 microns on both sides for better performance with close color match on top and bottom.
Standards
Substrate
