The addition of this additive to the liquid silicone rubber before it cures will create a more supple rubber with greater elasticity and a lower shore hardness. The product is inert making it safe for use in skin grade rubbers and food contact rubbers complying with FDA regulation 21 CFR 178.3570. The additive should be thoroughly mixed into the liquid rubber before it cures. With platinum addition cure rubber it can be added to either part A or part B or both.

Below is a guide to the effects, the results may vary slightly with different rubbers.
