Raw Material Room Temperature Vulcanizing RTV -2 Liquid Silicone Rubber for Cement Concrete Statue
Description of Tin Cure Silicone Rubber
HN-635 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.
Application of Tin Cure Silicone Rubber
HN-620 A/B Industrial-grade liquid silicone rubber for manufacturing construction molds is suitable for the molding and reproduction of large-scale stones, gypsum, cement parts, cultural stones, artificial stones, Roman columns, stone carvings and other furniture, construction and decoration products; it can also be used for
resin handicrafts, gypsum handicrafts, soap handmade soaps, tire turning molds, and other segmented molds.

Feature 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 release foam, easy to demould, and the finished product will not turn white;
3. The silicone mold can be turned over frequently and has a long service life;
4. The linear shrinkage rate is less than two thousandths;
5. Product color, hardness, viscosity, and operating time can be adjusted as needed.
Advantages of Tin-Cure Silicone Rubber
Main feature :
1. Environmentally friendly, non-toxic, tasteless, non-corrosive, passed MSDS, ROSH and other certifications.
2. Low viscosity, good fluidity, convenient operation and easy pouring; it can be cured at room temperature or heated.
3. Excellent physiological inertia, waterproof, ozone resistance and aging resistance, high tensile toughness, and many mold turning times.
4. High chemical stability, high and low temperature resistance, can be used for a long time and maintain its performance at -55°C to 220°C.
5. No low molecules are released during the cross-linking process, so the volume remains unchanged, the shrinkage rate is as low as 0.2%, and the precision is high.
