Food Moulding
Food safe silicone is suitable for Ice, chocolate, candy and speciality foods can be cast or moulded into decorative shapes by using silicone rubber mould making materials. Silastic® M silicone rubber may be suitable for these applications because of their food-contact status.
This rubber, when properly cured and cleansed is suitable for food contact in accordance with the requirements of FDA Regulation 21 CFR 177.2600. This regulation, covering rubber articles intended for repeated use, requires end user verification of compliance with applicable total extractives limitations.

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.
NOT TO BE USED WITH SILICONE THIXO OR PIGMENTS (Thixo and pigments are not certified for food use)
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.
