Silskin is a bicomponent (base and catalyst) addition RTV silicone rubber that vulcanizes at room temperature.
Indicated for special effects and the duplication of model
- High chemical resistance to the aggressive components of some types of resin;
- Extremely high tear strength (this feature guarantees high resistance to wear and tear);
- High accuracy in reproducing very small details;
- High dimensional stability in time and indeformability;
- Remarkable resistance to high temperatures and ageing

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.
