Abstract
A water-based dual-cure coating comprising the following raw material components: 15-25 parts by weight of a water-based polycarbonate dispersion, 30-60 parts by weight of a water-based aliphatic polyurethane acrylate dispersion, 5-15 parts by weight of a UV reactive diluent, 1-4 parts by weight of a photoinitiator, 0.2-1 part by weight of an auxiliary agent, 3-8 parts by weight of a film coalescing aid, and 5-15 parts by weight of water. The coating is sprayed onto an automotive interior part and subsequently cured by baking at a temperature of 50-65° C. to form a film, proceeding UV curing; and proceeding thermal curing at temperature of 70-80° C.
