Lord Adhesives CoolTherm™ UR-388 Flame Retardant Urethane Encapsulant System
Categories:	Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane, Adhesive
Material Notes:	LORD CoolTherm™ UR-388 encapsulant is a two-component urethane system designed for encapsulating and casting applications. CoolTherm UR-388 encapsulant cures at room temperature to produce a flame retardant, semi-flexible material. Features: exhibits low shrinkage and stress on components as it cures. maintains low viscosity for complete and void-free encapsulation. suitable for curing at room temperature; may be mildly heat cured (60°C) to expedite cure. exhibits low exothermic heat rise during room temperature cure. Provides excellent thermal shock resistance. provides excellent flame retardancy; UL 94 V-0 certified. exhibits low gassing properties in high vacuum environments. can be used on parts and devices that experience operating temperatures from -55°C to +130°C.
