摘要： The invention relates to an alkoxysilane functional polyurethane-urea that can be used to prepare an adhesive or coating composition. The polyurethane-urea is obtainable by polymerization of reaction components comprising: (a) an alkoxysilane functional thioether diol; (b) a polyisocyanate; and (c) an alkoxysilane functional aspartate ester, wherein the alkoxysilane functional aspartate ester (c) is a Michael addition product of an amino-functional silane and an unsaturated diester. The polyurethane-urea has a low viscosity and can be used in solvent- and water-free adhesives or coatings. The adhesive or coating can be applied to various substrates such as wood, wood-containing composite, metal, plastics, paper, stone, glass or concrete.

摘要： The present disclosure relates to a method of coating a non-conductive substrate, said method comprising the steps of: a) applying a coating composition to the substrate, wherein the coating composition comprises: i) at least one unsaturated compound, ii) a thermal initiator comprising an organic peroxide, iii) a photoinitiator, and iv) at least one pigment, wherein the coating composition is free of accelerator, is capable of decreasing the activation energy of the thermal initiator, and is free of Co compounds, b) exposing the coating composition to UV light effective to start polymerization of the unsaturated compound, and c) exposing the coating composition to microwave heating effective to decompose the thermal initiator, wherein step c) is performed either simultaneously with step b) or sequentially after step b).
