Creative Materials 127-31

127-31 is an extremely flexible one-component, syringe dispensable, 100% solids, thermally conductive, electrically insulating soft epoxy adhesive, encapsulant, and potting compound. This system features excellent thermal stability, chemical resistance and excellent high temperature properties. Unlike conventional thermally conductive epoxy adhesives, 127-31 features a low durometer and is highly flexible allowing it to absorb stress when bonding mismatched CTE substrates. 127-31 even displays some elastomeric properties. Applications include die attachment, printed circuit board fabrication, advanced material composites, LED attachment and heat sink bonding.

    Safety & Health

    Safety & Handling
    • Use with adequate ventilation.
    • Keep away from sparks and open flames.
    • Avoid prolonged contact with skin and breathing of vapors.
    • Wash with soap and water to remove from skin.

    Storage & Handling

    Shelf Life
    6 months at -10°C, max. 4 days at 25°C
    Suggested Handling & Curing

    If frozen remove product from freezer and allow material to warm to room temperature before opening container. Best results are obtained when curing at one of the following schedules:

    100°C 1 hour
    125°C 30 min
