HYPOX® RA 840

HYPOX® RA840 is a high-viscosity adduct of the diglycidyl ether of bisphenol A (DGEBA) and a butadiene-acrylonitrile (CTBN) elastomer. The elastomer improves the toughness and impact, thermal shock and peel resistance of the epoxy formulation. These improvements are attained with little loss of thermal resistance and modulus. HYPOX® RA840 adduct is suggested for use as a toughener in fiber-reinforced products, adhesives, molding compounds, potting and encapsulating compounds and chemical-resistant coatings. HYPOX® RA840 adduct can be blended with other bis-A epoxy resins to achieve the degree of toughening required.

HYPRO® and HYPOX® Reactive Liquid Polymers

Size of Bubble proportional to reactive group index

 - 1

Huntsman offers a broad range of HYPRO® and HYPOX® Reactive Liquid Elastomers that differ in Butadiene and Acrylonitrile content, as well as the nature of the reactive end group.
This allows formulators to balance properties and develop specific toughening solutions.
