1. The raw material is easy poisoning once contact with nitrogen, phosphorus, sulfur and heavy metal materials.

2.Part A and Part B can not be added at the same time , addition of Part B comes first ,followed by part A after full incorporation of part B into raw silicones , the order is important, A and B can not be mixed together.

3. The temperature of mixing machine which used for mixing silicone with platinum curing agent can not be higher than 45℃. Please add this agent after being cold.

4. The mixed raw materials should be used up within two days.

5. Please choose the suitable raw materials for hot air vulcanization,unmatched raw material will cause bubbles in the process.
