It’s always been a challenge to formulate thermoset epoxy resins, adhesives, coatings, and composites with high crosslink densities without them becoming brittle and prone to cracks. Reactive liquid polymers (RLP) can be added to epoxy formulations to meet this challenge. Hypro® RLP is low molecular weight synthetic rubber that has chemical functionality. These reactive additives impart rubber properties that can improve toughness, flexibility, and impact resistance. They can also increase T-Peel strength, impart low-temperature properties, and improve adhesion to substrates.
Hypro reactive liquid polymers are butadiene homo-polymers and butadiene-acrylonitrile copolymers with terminal functionality.
