CoolTherm® UR-2002 Thermally Conductive Urethane Gap Filler Where to Buy
Product Information
CoolTherm® UR-2002 gap filler is a two-component thermally conductive urethane system designed to provide excellent thermal conductivity for electronic applications. CoolTherm UR-2002 gap filler cures at room temperature to produce a flame retardant, compliant material.
Shelf Life
Shelf life is six months for CoolTherm UR-2002 resin and four months for CoolTherm UR-2002 hardener when stored in clean, dry environment at 5-30°C in original, unopened container.
When stored at cooler temperatures, containers may need to be gently warmed before dispensing for ease of use. Limit heating period to less than three hours as excessive heating will cause dimerization of the hardener.
After opening, protect each component from exposure to moisture by using dry nitrogen as an inert cover each time material is removed. Do not return dispensed material to its original container.
Features and Benefits
Thixotropic Viscosity – maintains low viscosity during dispensing, with minimal flow after dispensing.
Flame Retardant – provides excellent flame retardancy.
Room Temperature Cure – suitable for curing at room temperature; may be mildly heat cured (65°C) to expedite cure.
Reworkable – material compliance allows for reworkability of cured parts.
