Caprolactone Monomers

Based on 16 products - Last update on the Jun 26, 2025

Caprolactone is a clear, low-viscosity liquids that polymerize reactions to form high-performance resins with superior mechanical strength. Key benefits include enhanced film formation, improved weatherability, and resistance to solvents and moisture. They are ideal for automotive, industrial, and wood coatings, where long-term durability and environmental exposure resistance are critical. 

Manufacturers are developing caprolactone-modified polyesters and polyurethanes to comply with stricter environmental regulations while maintaining excellent mechanical properties. Regulatory guidelines, including REACH and EPA standards, favor low-toxicity and biodegradable resins, driving interest in bio-based caprolactones.

PLACCEL® FM1D

by Daicel

PLACCEL® FM1D by Daicel is a caprolactone-modified methacrylate with reduced inhibitor content. It has hydroxyl and methacrylic functionality for dual cure systems. It offers faster reactivity with isocyanates, improved adhesion and physical performance. It provides weathering- and oil resistance. It is recommended for use in coatings.

Capa® Monomer

by Ingevity

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.
