                        Quantum Silicones鈥? High Strength Gel



Product Description



       QGel 300Y is a very soft, tough, moderately cross-linked silicone polymer.

Silicone gels are used to provide protection from vibration, thermal or mechanical shock.

Silicone gels also provide excellent moisture protection. QSi鈥檚 QGel product line are two

component materials with a 1:1 mix ratio.

QGels have excellent dielectric strength



Instructions for use



Mixing



       The convenient one to one mix makes QSi鈥檚 QGels 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.



De-aeration



       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



        QGels should be stored in the original unopened container at 25C (77F). They

will remain useful for a period of 12 months if stored under those conditions.
