Colorite Abrasion Resist
ColoRite Abrasion Resist is a Polyurethane Polyamide pre-painted galvanized steel developed to provide high durable material for applications requiring high abrasion resistance. The paint is a Polyurethane Polyamide system, applied on a Galvanized substrate of Minimum 180 GSM (G60) zinc coating, with paint film thickness of 25µm on weathering side and 20µm of the same system on the bottom side.
Anti-Weathering Limited Warranty: 7 Years (UNICOIL Technical terms and conditions applicable).
Substrate
Galvanized steel – G60 (180gsm)
