Film Forming compositions curable Low Gloss and resistance to Burnished, and Methods for improving the Resistance of a substrate Polishing

摘要

A curable Film Forming composition comprising: (a) a polymeric Binder comprising: (i) a polysiloxane with reactive Functional groups and in which there are dispersed ParticleS of silica protonated which have an average particle size of 2 to 20 micrometers,Where the polysiloxane is present in the polymeric Binder in an amount of at least 10 percent by weight based on the total weight of solids in the polymeric Binder; and (ii) optionNow, at least one additional different polysiloxane polymer resin (i)With reactive Functional groups; and (b) a Curing Agent which contains Functional groups that are reactive with the reactive Functional groups of (i), (ii)Or both; where after application to a substrate and Coating after Curing.The Film Forming composition curable presents an initial brightness of at least 30 85 and increased brightness in 85 of not more than 10 units of brightness when subjected to one of the ENSA methodI Abrasion in wet State, where one of the test method of abrasion test in wet State corresponds to the car wash - AMTEC Kistler in accordance with DIN 55668,Made 10 Cycles.
