Description of Tin Cure Silicone Rubber
HN-620 A/B is a two-component liquid silicone material. Two components are mixed in a ratio of 100:2. This product is cured at room temperature.
Component A is a flowable liquid silicone, while Component B is a curing agent (vulcanizing agent) that can be quickly formed by mixing the two.
Application of Tin Cure Silicone Rubber
① Molds for plaster, cement, and concrete products (the most classic application)
② Molds for wax modeling/investment casting
③ Molds for low-melting-point alloy casting
④ Molds for resin crafts and polyester resin components
⑤ Molds for soap and candle making
⑥ Prototype making and mold casting
Feature of Tin Cure Silicone Rubber
1. Strong tear resistance, high and low temperature resistance, acid and alkali resistance, and aging resistance;

Compared with others, Hannast molding silicone has better flexibility and stronger tear resistance, and the silicone mold has a longer service life and can be reused many times.
Low shrinkage and precise reproduction
The shrinkage rate is negligible, ≤2‰, enabling the reproduction of the finest and most complex details.
Non-Toxic & No Odor
Made of premium silicone material, liquid silicone rubber will not produce unpleasant odors, allowing you to use more assured
Good Fluidity
Liquid silicone rubber has good fluidity, self-leveling, easy-release bubbles,and easy pouring to help complete the mold.
