HYPRO® 2000X168 VTB is a 100% solids liquid rubber designed to enhance toughness, flexibility, adhesion, and impact resistance in thermoset resin systems, including epoxies, vinyl esters, unsaturated polyesters, acrylics, and urethanes. This methacrylate-terminated butadiene homopolymer, derived from the reaction of CTB 2000X162 with glycidyl methacrylate, is used primarily by blending with acrylic, PVC, vinyl ester, or unsaturated polyester resins to improve product performance. Containing no acrylonitrile, it is commonly used at 5% to 20% of total solids and forms rubber domains when cured, providing key performance benefits.
