摘要:
A composition comprises (a) a binder component which comprises (1) 5 to 100 weight percent of at least one natural oil derived polyol having at least about 50 percent primary hydroxyl groups and (2) sufficient additional polyol different from a natural oil derived polyol to make 100 percent wherein the natural oil derived polyol has an average of from 1.5 to 3 hydroxyl groups per molecule and an equivalent weight of from 200 to 5000; and (b) a crosslinking component reactive with hydroxyl groups. Furthermore, a process for producing a coating, adhesive, binder or combination thereof on the surface of a substrate, comprises in any order: (a) admixing binder and crosslinking components of a composition to form an admixture, wherein a binder component comprises (1) 5 to 100 weight percent of at least one natural oil derived polyol having at least about 50 percent primary hydroxyl groups and (2) sufficient additional polyol different from a natural oil derived polyol to make 100 percent wherein the natural oil derived polyol has an average of from 1.5 to 3 hydroxyl groups per molecule and an equivalent weight of from 200 to 5000; and (b) applying a layer of said admixture on said surface. The invention includes coatings, adhesives, binders and combinations thereof prepared from any composition of the invention, substrates coated by the process of the invention or coated using a composition of the invention and articles, including laminates, comprising a coating, adhesive, binder or combination thereof of the invention.
