SEMICOSIL 920 LT A is a pourable, addition-curing, two-part silicone rubber that cures to a soft silicone gel.

All surfaces must be clean and free of contaminants that will inhibit the cure of SEMICOSIL 920 LT A. Examples of inhibiting contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds – especially organotin compounds. If a substrate's ability to inhibit cure is unknown, a small-scale test should be run to determine compatibility.

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
