Item Polycraft Silicone Putty RTV Moulding Rubber
Size 500g Kit
Information

Polycraft silicone putty is a fast curing silicone rubber, cured at room temperature with excellent dimensional stability and is used for the rapid reproduction of objects.

Polycraft Silicone Putty is ideal for small mouldings and will replicate excellent detail from the original object producing a strong semi-flexible reusable mould. It has excellent self-releasing properties and will not require release agent for most applications. Ideal for a wide range of impression type moulding applications such as ornate plaster decorations, polymer clay to figurines etc.

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 clay's, sulphur vulcanised rubbers, condensation cure silicone rubbers, wood, paper, cardboard, onion and garlic.

Base and catalyst use universal containers for various kit sizes and are supplied by weight, while the supplied containers may not be full, they will contain the correct amount of both base and hardener according to the listing. At point of packaging and dispatch lids may be taped to prevent damage or spillage during transportation.
