CURABLE FILM-FORMING COMPOSITIONS DEMONSTRATING BURNISH RESISTANCE AND LOW GLOSS AND METHODS OF IMPROVING BURNISH RESISTANCE OF A SUBSTRATE

摘要

(A) (i) a polysiloxane having reactive functional groups dispersed in protonated silica particles having an average particle size of from 2 to 20 μm; And (ii) a polymeric binder comprising at least one additional polymeric resin optionally having a reactive functionality different from the polysiloxane (i); And (b) a curing agent containing a functional group that is reactive with the reactive functional groups of (i) and / or (ii). After application to the substrate as a coating and after curing, as measured by the various abrasion test methods defined herein, the curable film forming composition exhibits an initial 85 ° gloss of less than 30 and an 85 ° gloss increase of less than 10 gloss units. Also provided is a method for improving the burnishing resistance of a substrate using the curable film forming composition of the present invention.
