摘要

Coating compositions comprising a binder (60-90 wt. %) and an organic carrier liquid (10-40 wt. %). The binder comprises (wt. % of binder): (a) hydroxy functional oligoether (5-50); (b) hydroxy functional (meth)acrylic copolymer (40-60), including cycloaliphatic (meth)acrylate comonomer and/or an alkyl substituted aromatic vinyl comonomer (at most 10) (c)polyisocyanate crosslinkers (5-40); and (d) a curing catalyst.
