UN PROCEDIMIENTO PARA REVESTIR UN SUBSTRATO TAL COMO MADERA,METAL , MATERIAL SINTETICO O MATERIAL CAUCHOIDE.

摘要

Liquid, curable coating compositions are provided based on an addition polymer containing hydroxyl groups and a curing agent. The compositions have a high solids content and hence a low solvent emission upon application. The addition copolymer contains structural units derived from isobornyl (meth)acrylate and/or a mono-ethylenically unsaturated compound of decahydronaphthalene and/or tricyclo(5.2.1.02,6 ) and has a Mn of 600-15000 and a hydroxyl number of 30-320. The curing agent may be (blocked) isocyanate or methylolated aminoplast resin. The composition may be applied to vehicles as a top coat.
