Lord Adhesives Thermoset™ UR-329 Two Component Urethane Potting Compound
Categories: Polymer; Adhesive; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Adhesive

Material Notes: Lord UR-329 is a flexible, two-component, room temperature curing, urethane, encapsulating compound. UR-329 maintains low hardness and modulus over a wide temperature range, which imparts minimal stress on delicate electronic components. UR-329 is a filled system, which enhances its ability to dissipate heat. It is often suitable in applications operating up to 130°C. UR-329 also exhibits excellent thermal shock resistance, very good electrical properties and good adhesion to a variety of materials.
