Abstract
Abstract A coating and adhesive composition which comprises an ethylene-acrylic elastomer, a high molecular weight polyvinyl chloride and a filler, preferably carbon black. The composition is cured with a suitable catalyst, preferably an amine catalyst, to form an abrasion resistant coating, which can also be employed as a repair coating, especially for damaged plastic materials or sheets on a substrate, particularly sheets formed from ethylene-acrylic elastomer. The composition can also be employed as an adhesive or bonding material for such plastic sheets.
