FDA Grade Platinum Cross-linking Agent

C-100A/B

C-100A & B, two component platinum addition type cross linking agent which is added in the raw silicone for the cross linking of Food and Medical Grade silicone rubber items, The vulcanized products can pass the FDA test, it features with Non-toxic, Odourless, High Grade of Transparency, Well Anti-yellowing and other properties.

Good for both compression molding and extrusion forming. This agent are mainly applied to Food Grade and Medical Grade products, such as baby nipples, cake mold, silicone cookwares, extrusion gaskets, ice mold, table matt, medical silicone tube and so on.

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.
