CoolTherm® MT-125 Thermally Conductive Adhesive Where to Buy
Product Information
LORD CoolTherm® MT-125 thermally conductive adhesive is a rapid cure, one-component adhesive specifically designed for applications requiring a long working life adhesive with high thermal conductivity. CoolTherm MT-125 adhesive is suitable for use as a thermal interface adhesive for heat sink attachment and other applications requiring good adhesion and heat transfer properties.
Shelf Life
Shelf life is six months from date of manufacture when stored at -30°C in original, unopened container. Syringe must be maintained at -30°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.
Features and Benefits
Fast Cure – rapidly cures at 150°C.
Excellent Adhesion – provides excellent adhesion to ceramics, aluminum and other metal substrates.
High Thermal Conductivity - provides high thermal conductivity for applications where superior heat dissipation is required.
Excellent Dispensability - allows high-speed, accurate syringe dispensing of fine dots or lines; can be used with time/pressure, positive displacement or linear dispense heads.
