RTV -2 Industrial Liquid Silicon Rubber Silicone for Casting 3D Resins
Description of Tin Cure Silicone Rubber
HN-625 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-625 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.

Attention
1. There are 30 minutes of operation time (at room temperature) when adding 2% curing
agent, and the mold can be completely cured in 4 hours. Generally, the mold is better
placed for 24 hours before use. At this time, the performance of the mold is relatively
stable in all aspects, and the use effect will be better.
2. The mixing ratio of silicone and curing agent is 100:2-3. For example, 100 grams of
silicone, add 2-3 grams of curing agent. In principle, do not take the method of adding
less or more curing agents.
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.
