Lord Adhesives Thermoset™ UR-340 Two Component Urethane Encapsulant
Categories: Polymer; Adhesive; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Adhesive
Material Notes: Lord UR-340 is a two component, room temperature curing, urethane encapsulating compound. It is low in viscosity and has excellent flow characteristics. Its flexibility, low modulus characteristics, and very good electrical properties make it a good choice for encapsulating sensitive electronic components. UR-340 is often suitable in applications operating up to 130°C.
