Material Notes:
Lord UR-322 is a two component, room temperature curing urethane potting compound. The cured elastomer is soft, flexible and has a very low modulus at temperatures down to -80°C. Cured UR-322 also has excellent thermal shock resistance, electrical properties and adhesion to a variety of materials. The hydrophobic nature of this resin system imparts exceptional hydrolytic stability to the cured resin.All information provided by Lord.
