Precautions
1. Do not use natural rubber gloves. Silicone Impression Putty is recommended to use disposable polyethylene plastic gloves.
2. Silicone Impression Putty contains platinum catalyst, sulfur, phosphorus, amine, etc. will slow down or even stop the curing reaction, and thus it must avoid sulfur, phosphorus, amine, acrylic and meth acrylic acid esters and other chemical products in use.
3. Close the lid tightly and immediately after use, keep Silicone Impression Putty in cool place, and be refrigerated in summer.
4. The temperature has a significant impact on the curing time; the curing reaction will slow down at low temperature, and speed up at high temperature curing speed. It should adjust operation rhythm according to the environment and the finger temperature.
5. Silicone Impression Putty is strictly recommended to use the same amount of base and catalyst. Unequal amount will lead to delayed or accelerated cure.
