摘要

A single-layer two-component polyurethane lacquer which is particularly suitable for the high-gloss coating of polystyrene. A lacquer which can be sprayed having a potlife of at least 16 hours and a flash point exceeding 21 DEG C. is obtained by using tertiary alcohols and diacetone alcohol as a solvent, to which a thermoplastic acrylate resin is added as an adhesive.
