Crosslinkable coating compositions cured by a specified blend of alkylarylsulphonic acids |
摘要 |
Coating compositions capable of curing at or near to room temperature comprise 90-50% by weight of a specified hydroxyl group-containing addition polymer, 10-50% by weight of an alkylated melamine-formaldehyde crosslinking agent and an acid catalyst consisting of a blend of a C1-4 alkylated arylsulphonic acid and a C8-14 alkylated arylsulphonic acid in amounts such that the -SO3H group content is 0.70-2.1% of the total weight of the addition polymer and the crosslinking agent. The compositions are particularly suitable for the refinishing of automobile bodies.
