QGel 3215導熱墊片 Thermal Pad


• one to one mix ratio
• soft but resilient gel
• dispensing equipment not necessary


is a clear moderately cross-linked silicone polymer with a long work time.
Silicone gels are used to provide protection from vibration, thermal or mechanical shock.
Silicone gels also provide excellent moisture protection. This product is a two component
material with a 1:1 mix ratio.

Instructions for use

The convenient one to one mix makes QSi’s Q-Gels very easy to mix. Mix equally and
thoroughly by weight or volume. Once the components are mixed the curing process
begins. The pot life of the mixed material is shown under typical properties. Fast curing
gels (less than 30 minutes pot life) should be dispensed utilizing automated mix and
dispense equipment.

Air trapped during mixing should be removed to eliminate voids in the cured product.
Vacuum de-airing may be necessary to completely remove all entrapped air bubbles. To
insure proper de-airing, subject the mixed material to 29 inches of mercury.

Storage and shelf life
Q-Gels should be stored in the original unopened container below 38C (100F). They
will remain useful for a period of 12 months if stored under those conditions.
