Electron-beam curing of lacquer coatings. Part II. Lacquer binders based on unsaturated polyester resins
and acrylated epox yresins
The results of investigations of radiation curing of lacquer coatings with binders based on unsaturated polyester resins and acrylated epoxy resins have been presented. The influence of coaling composition on the dependence of gel content vs radiation dose has been determined. It has been pointed out that the presence of multifunctional monomers, e.g. trihydroxymethylpropane triacrylate, increases the hardness of coating surface, especially for systems containing epoxy-acrylic resin. It has been found that an addition of monomer diluent, e.g. vinyl acetate, decreases the viscosity of coating based on acrylated epoxy rosins, and the hardness of coating is not decreased.
