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.

NYCHEM® 1581 is a carboxylated, high-nitrile acrylonitrile-butadiene latex offering excellent chemical and mechanical stability. It provides superior formulating capabilities, wetting properties, and reduced pH sensitivity, ideal for binder and coating applications. As a wet laminating resin or heat seal adhesive, it offers strong adhesion to rubber, metal, and textile substrates, enhancing water, oil, solvent resistance, and flexibility. With high acrylonitrile content, it excels in chemical, grease, and oil resistance, making it ideal for abrasive and durable papers. Its carboxylated functionality enables crosslinking, and vulcanization with sulfur donors further improves toughness and resistance.
