Alcohol Soluble Polyester Resin
REACTOL™ 5145 A is a highly structured, flexible polyester resin. It exhibits excellent solvent release, high gloss, and low viscosity. Due to its outstanding nitrocellulose compatibility, REACTOL™ 5145 A can be used with nitrocellulose in place of or as a partial replacement for the Flex-Rez™ resins. REACTOL™ 5145 A is an adhesion promoter in hard resin systems. In addition, REACTOL™ 5145 A has high solubility in alcohols and is insoluble in drying oils and low Kb hydrocarbon solvents.
