Feature of Tin Cure Silicone Rubber
1. Strong tear resistance, high and low temperature resistance, acid and alkali resistance, and aging resistance;
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.
