Instructions for use
Mixing
Mix at a 10:1 ratio by weight . Once the components are mixed the curing
process begins. The pot life of the mixed material is shown under typical properties.
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
QSil 602 should be stored in the original unopened containers at 25C (77F). They
will remain useful for a period of 12 months if stored under those conditions.
