Capa® Monomer

Capa® Monomer by Ingevity is a colorless, low viscosity caprolactone monomer. It is a cyclic ester with a lactone ring that is relatively easily opened by compounds containing active hydrogen atoms such as alcohols. Each ring opening step forms a terminal, primary hydroxyl group. It exhibits excellent UV resistance, consistent crystallization, high flexibility even at low temperatures and low viscosity. It possesses hydrolytic stability, excellent strength, abrasion resistance and high and low temperature service interval. It is non-toxic, easy to process, biodegradable and has low impurities. Capa® Monomer is used as a flexibilizing monomer in unsaturated polyester gel coats. It is applicable in paints and inks. It can also be used as a reactive diluent in epoxy resins. It is suitable for high solid coatings, one-component (1K) stoving enamels and two-component (2K) waterborne and solvent-borne polyurethane coatings.
