Bulk Liquid Silicone 100:2 Tin Cure Silicone Translucent Rtv 2 Molding Silicone Rubber For Molds Heat Cured
Bulk Liquid Silicone 100:2 Tin Cure Silicone Translucent Rtv 2 Molding Silicone Rubber For Molds Heat Cured
Description of Tin Cure Silicone Rubber
This product consists of AB dual component, A component silicone, and B component curing agent. During operation, mix the AB two components in a weight ratio of 100:2-2.5 (1:1 for addition molding), stir evenly, and then solidify to form
Features of tin cure silicone rubber:
① Strong tear resistance, high and low temperature resistance, acid and alkali resistance, and aging resistance;
② Good fluidity, easy to remove foam, easy to demould, and the product produced does not turn white;
③ The silicone mold has multiple times of mold flipping and a long service life;
④ The linear shrinkage rate is less than one thousandth;
⑤ The product color, hardness, viscosity, and operating time can be adjusted as needed.
Application of Tin Cure Silicone Rubber
Cultural stone mold silicone is suitable for the replication and production of cultural stone, cement parts, gypsum, large stones, artificial stones, Roman columns and other furniture and architectural decoration products.

When the amount of curing agent added is 1%, the colloid will still flow after 2.5 hours and can be demolded after 6-8 hours;
When the amount of curing agent added is 2%, the colloid will still flow within 50-1 hour, and demolding can be carried out within 2-3 hours;
When the amount of curing agent added is 3%, the colloid will still flow after 28 to 30 minutes, and demolding can be carried out after 1.5 to 2 hours;
When the amount of curing agent added is 4%, the colloid will still flow within 10-15 minutes and can be demolded within 1-1.5 hours.
