Polymerization: Addition Cure
PlatSil FS-20 (Fast-Setting) Silicone Rubber is a two-part, platinum-catalysed, liquid silicone system that cures (RTV) to a milky white, Shore A20 rubber. This product offers a simple 1A:1B mix ratio (by weight or volume), a fast demold time of 25 minutes, and a long pour time (8 minutes) relative to its cure speed. This allows for fast turn-around of moulds and parts with sufficient time to mix and pour. Heat can be used to further accelerate the cure.
FS Stands for Fast Setting NOT Food Safe.

Inhibition of Cure
Great care must be taken when handling and mixing all addition-cured silicone elastomer systems, that all the mixing tools (vessels and spatulas) are clean and constructed in materials which do not interfere with the curing mechanism, do not use wood and paper mixing utensils. The cure of the rubber can be inhibited by the presence of compounds of nitrogen, sulphur, phosphorus and arsenic; organotin catalysts and PVC stabilisers, epoxy resin catalysts and even contact with materials containing certain of these substances e.g.. moulding clays, sulphur vulcanised rubbers, condensation cure silicone rubbers, wood, paper, cardboard, onion and garlic.
