Abstract
Disclosed are coating compositions, wearlayer compositions and surface covering products which utilize wearlayer compositions. The wearlayer compositions of the present invention are capable of at once exhibiting high initial gloss values and excellent resistance to scuff, stain and gloss loss. Such wearlayer compositions are produced utilizing curable coating compositions which comprise thermoplastic polymer, from about 3% by weight to about 25% by weight of plasticizer for the thermoplastic polymer and at least about 30% by weight of reactive crosslinking agent. The weight ratio of the thermoplastic polymer to the crosslinking agent is preferably no greater than about 2:1.
