REACTIVE MIXTURE FOR COATING MOLDED OBJECTS BY MEANS OF REACTION INJECTION MOLDING AND COATED MOLDED OBJECT |
摘要 |
The present invention relates to a reactive mixture for coating mouldings by means of reaction injection moulding, comprising at least 40% by weight of (meth) acrylates having at least two double bonds, the reactive mixture comprising at least one photoinitiator and at least one thermal initiator. The present invention furthermore describes a coated moulding comprising a moulding which is obtainable by injection moulding processes and comprises at least one polymer selected from the group consisting of polymethyl methacrylate, polymethylmethacrylimide, styrene-acrylonitrile copolymer, styrene-maleic acid copolymer and polymethyl methacrylate copolymers, and a coating which is obtainable by polymerization of (meth) acrylates having at least two double bonds, the coating having an adhesive strength rating of not more than 1 according to the cross hatch test and a decrease in gloss at 20° after a scratch resistance test according to ASTM 1044 (12/05) (applied weight 500 g, number of cycles = 100) of not more than 10%. |
