This company, an Emerald Performance Materials company, has introduced a new glycidyl ester product line. The patent-pending technology addresses a need in the marketplace for impact modifiers that deliver both high peel strength and high impact strength while maintaining a high Tg in the epoxy matrix. The new products can provide effective alternatives to traditional core-shell and high-molecular-weight non-epoxy type polyols used as impact modifiers, which may offer either high impact or high peel adhesion but typically are not delivered optimally.

New products include Hypro 1300X63 ETBN, Hypro 1300X68 ETBN, and Hypro 2000X174 ETB. The first two are diglycidyl esters of low-molecular-weight butadiene-acrylonitrile copolymer; the third is a diglycidyl ester of a low-molecular-weight butadiene homopolymer. All three products are designed to function as toughening agents for applications such as molding, adhesives, impact-resistant coatings, prepregs and composites when used at low levels.
