Warm Tips
1. 8 series platinum cure silicone is very easy to cause cure inhibition, so please do remember thoroughly clean the model and tool before operation. Besides, please avoid the condensation silicone rubber (100:2) contact or mix with the following material, otherwise the silicone won’t be cured.
2. Liquid condensation silicone(condensation silicone not completely cured or organic tin compounds)
3. Sulphur, sulfide and sulfur rubber materials.
4. Amine compounds as well as contains the amine materials.
5. Impurity, organic tin catalyst, acid, alkaline and other organisms containing sulfur, phosphorus and nitrogen will influence the vulcanization of the silicon rubber
