Abstract
A coated substrate including a 1 to 3 mils thick coating layer has a Bayer abrasion resistance value of less than 1% Haze after 600 cycles. The coating layer includes a reaction product of a coating composition including a polyester diol, a di-isocyanate, and a fluorocarbon-based additive. A method of forming the coating layer on the substrate includes mixing reactants including a polyester diol, a di-isocyanate and a flurocarbon-based additive to form a polyurethane coating composition; depositing the polyurethane coating composition on the substrate; and curing the polyurethane coating composition to form an abrasion resistant coating on the substrate.
