CHT Group EP AOSR EPI Engineered Polymers Acrylic Oligomer
Categories: Polymer; Thermoset

Material Notes: EP AOSR, is an aliphatic triacrylate oligomer and is "Powered by Reactamine ®Technology”. EP AOSR is light in color and has fast cure response to UV and EB. EP AOSR exhibits good flexibility, toughness, abrasion resistance, water resistance, and excellent non-yellowing properties.

EP AOSR when used in unsaturated polyesters, allows the styrene monomer content to be reduced to lower V.O.C.’s. Impact strength in gel coats improves, UV stability improves, water resistance increases, and gloss retention is higher. Laminating resin improve in cure and Barcol hardness.

Part of the Amber Chemical Group. Data provided by manufacturer.

Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
