PART A and PART B are both clear liquids which are odourless and non-toxic. They react to form a translucent beige/off white coloured flexible, elastic material with high tensional and tear strength. It has outstanding release properties, a high chemical resistance and a temperature resistance of 250°C.
The two components mix easily with a simple 1:1 ratio and because of the low viscosity can be used without a vacuum chamber. There is practically no shrinkage (0.1%) and excellent reproduction of fine detail.
The pot life is approximately 8-12 minutes and the cure time is 1-2 hours.
Available in two hardnesses, soft and medium. The soft is better suited to moulding delicate, fragile items where the rubber needs to be soft and flexible enough to peel off without damaging the casting. The medium is suitable for the majority of cases.
This rubber is suitable for casting a wide range of materials including for use with confectionery, speciality foods and is safe for contact with skin for life castings. Please see below for more details.

SUITABLE FOR USE WITH
Sugar craft & confectionery
Epoxy resin *
(* Excl. some epoxies, check with supplier of the resin if silicone moulds are suitable.)
Metals with a pouring temperature below 250°C
Great care must be taken when handling and mixing all addition-cured silicone elastomer systems. All the mixing tools (vessels and spatulas) should be clean and constructed in materials which do not interfere with the curing mechanism. 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 these substances e.g. moulding clays, sulphur vulcanised rubbers, condensation cure silicone rubbers, onion and garlic.
