Abstract
Two series of ultraviolet (UV)-curable waterborne polyurethane-acrylate coatings were prepared from oligomer containing unsaturated double bond (-CH=CH2 ), acrylate active diluents and photoinitiator. The physical properties of oligomers, properties (solvent resistance, mechanical behavior, contact angle, thermal properties and surface free energy) of UV coating films, and the effect of UV curing time on the contact angle of films were investigated. The prepared UV[1]curable coating was selected to protect the surface pigment on stone substrate. The results indicate that the prepared UV-curable waterborne polyurethane acrylate coating has excellent surface sealing properties and good application prospects in protect surface pigment on stone substrate.
