Platinum vulcanizing agent
Product introduction:
Characteristics:
- l No new low molecules after vulcanization
- l Odorless
- l Rapid vulcanization speed and low molding temperature
- l Excellent physical properties after formation
- l One time vulcanization ,without secondary vulcanization
Application:
- l Mainly used for low temperature vulcanization and silicone with odorless or thick products.
- l Such as: molded silicone nipple, cake pan, ashtray, sealing ring, silicone bag, PC mobile phone case or thick silicone product
Attentions
- l Avoid to contact with nitrogen, phosphorus, sulfur and heavy metal materials,they will cause dead materials.
- l The cross linking agent is added by weight to Part B and should be thoroughly mixed into Part A after adding Part B,the order is important. A and B can not be mixed together.
- l The temperature of mixing machine which used for mixing silicone with this agent can not be higher than 45°C.Please add this agent after being cold.
- l Thoroughly vulcanized materials by this agent must be used up within two days.
- l Pleasechoose the suitable raw materials for hot air vulcanization, bad raw materials will cause bubbles.
- l Platinum A and B rubbers should be placed in a space where the temperature should not exceed 25 ° C after being uniformly tempered with each other, and used within 8 hours.
To prevent cross-linking under room temperature

Method of Application
- lTake 20KG as an example: TNA-65PJ: 0.6% × 20KG = 120g (A);
TNB-65PJ: 2.0% × 20KG = 400g (B). Mix 10KG Silicone Rubber and 120g TNA-65PJ first. Mark as A and let stand for about 30 minutes. Then mix 10KG Silicone rubber and 400g TNB-65PJ and mix it evenly and mark it as B, let stand for about 30 minutes. Before vulcanization molding, take equal amounts of A and B to each other to be used for extrusion vulcanization molding. (Used after cooling, the effect is best.) A, B mixed raw materials need to be placed In a space where the temperature does not exceed 250C, it should be used within 8 hours to prevent cross-linking at room temperature.
- l Application Ratio is Adjustable.
