Rtv2 Silicone Rubber Tin Cured Raw Material Industrial Grade Silicone 2 Part Rubber Mold Making for Gypsum Sculpture

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.
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
Tear-resistant and long-lasting
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.
