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.
