CoolTherm® MT-220C Thermally Conductive Adhesive Where to Buy
Product Information
LORD CoolTherm® MT-220C thermally conductive adhesive is a fast cure, one-component, silicone hybrid adhesive used for bonding silicone to silicone and metal to metal, as well as ceramic, plastic or metal lids to a heat sink. The cured adhesive offers superior adhesion strength, extremely high thermal conductivity and excellent temperature cycle performance, making it ideally suited for demanding applications such as automotive under-the-hood devices.
Shelf Life
Shelf life is six months from date of manufacture when stored at -40°C in original, unopened container. Syringe must be maintained at -40°C in a vertical (upright) position with the dispense tip facing down. Do not store syringe on its side (horizontally).
This material is shipped and stored frozen. Consult handling instructions** for thawing.
**Handling instructions are available on LORD.com.
