Epoxol® RD181

Epoxy Diluent

EPOXOL® RD181 is a low viscosity, 100% solids non-hazardous reactive epoxy diluent produced from a bio-based, renewable resource. It is a clear, aliphatic liquid with mild odor. This product is used to reduce viscosity of epoxy resins and enhance performance properties.

Functions & Benefits

EPOXOL® RD181 is an epoxy-functional diluent that’s highly efficient at reducing the overall viscosity of epoxy resins. Unlike typical alkyl glycidyl ether diluents, EPOXOL® RD181 is non-hazardous, non-chain terminating, and can improve the overall toughness (abrasion resistance, impact resistance, and flexibility) of epoxy formulations. It has excellent compatibility with BPA, BPF and Novolac epoxy resins, and is suitable for use in a wide variety of coatings, adhesives, composites, electrical castings, flooring and civil engineering products.
