| Abstract: | Based on unsaturated polyesters(UP) and epoxide acrylate (EA) resins used as matrix resin of UV curing powder coatings,the effects of resin structures and ratios on curing degree and properties of the cured film were studied.The results showed that the curing degree was a key to the cured film properties such as resistance to organic solvents,adhesive attraction,pencil hardness and impact strength;the appropriatenn(UP)/n(EA) was 1/1 and curing degree should be more than 95%. |
