CVC Thermoset Specialties Introduces Glycidyl Ester to Deliver High Impact and Peel Strength

Published on 2010-10-28. Author : SpecialChem

CUYAHOGA FALLS -- CVC Thermoset Specialties, an Emerald Performance Materials Company, introduces new product line of glycidyl ester. The company's 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 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 while 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. At high loadings they offer unique highly elastomeric properties to epoxy systems even at temperatures below -40C.

The new product platform represents an expansion of Emerald's legacy CTBN reactive liquid polymer technology which combines the technology it acquired from its predecessor, BFGoodrich, along with technology the company acquired from CVC Specialties Inc. in 2008.

"The new platform is a great example of the technological synergy created in bringing these two businesses together," said John Cech, president of CVC Thermoset Specialties. "Our company has always focused on delivering performance and value to customers through creative solutions. This innovation addresses a key customer need and allows us to take the reactive liquid polymer platform into new areas."

Unlike traditional epoxy resin adducts, the new products are essentially 100% epoxy functional rubber. As compared to traditional CTBN adducts which typically use bisphenol A, bisphenol F carrier resins or other diluents, these new glycidyl ester modifiers do not utlize resins or diluents. Because of this, these modifiers can be used in any epoxy system as there in no limiting compatibility from the carrier resin. The new glycidyl ester additives also allow formulators to modify resin systems so they can achieve lower formulated viscosities at equal rubber content, which may be a processing advantage in certain applications, while maximizing Tg, lap shear, and peel adhesion.
