Moulding Silicone on Platinum Catalyst 20 ShA.
GENERAL DESCRIPTION: Two-component platinum-based silicone rubber. Hardening at room temperature. Exceptional fluidity, convenience and ease of use, easy demoulding. Good tensile, elasticity, tear strength, no shrinkage. High replicability and durability of operation.
Used for moulding of polyurethanes, polyester resins, plaster, wax, paraffin, gypsum, concrete, liquid plastics, soaps. For the production of souvenir products, sculptures, figurines and other handicrafts.
RECOMMENDATIONS:
Mechanical as well as manual mixing is acceptable. Make sure the compound has a room temperature before mixing the components. Keep in mind that when storing (or transporting) material outdoors in cold weather, it may take up to 24 hours for the components to reach room temperature. The optimum room temperature during moulding should be 20-25 °C, and the humidity should not exceed 50%. Use a clean and dry container to mix the components. Mix the mixture thoroughly for 2-3 minutes, periodically scrubbing from the sides and bottom of the container.
