Abstract
Novel Vinylester resin of p-dihydroxy benzene (VER-HQ) was prepared by the reaction between diglycidyl ether of hydroquinone and acrylic acid. The VER-HQ resin was characterized by its viscosity, acid value, number a verge molecular weight and IR spectrophotometry. Curing conditions for the resin were established by differential scanning calorimetry. Thermal stability of the resin was studied by thermogravimetric analysis. The VER-HQ resin was coated on mild steel panels and the coated panels were tested for their flexibility, impact strength, scratch hardness and chemical resistancy. Vinyl monomer such as styrene lowers the curing temperature of all resin systems when incorporated prior to curing and significantly improves the properties of coating.
