Platinum catalyst is a colorless or light yellow liquid, which is a highly active and efficient platinum catalyst. It can efficiently catalyze Si Vi and Si-H addition reactions without any side reactions. At the same time, this product also has the advantages of good stability and strong anti toxicity, which effectively avoids the generation of black substances during storage or use, and reduces the impact of nitrogen-containing and sulfur-containing substances.

Application field of platinum catalyst: it can be used as a catalyst for liquid addition silicone rubber, silicon gel, addition compound, electronic potting rubber, silicone ink, etc; Catalysts for the synthesis of polyether silicone oil, amino silicone oil, etc; Other occasions of hydrosilylation reaction; Paper isolation agent; Modified organosilicon; Flame retardant silicone products are efficient and environmentally friendly flame retardants.
  
 Usage of Platinum Catalyst:


 a、 When preparing pre mixed rubber materials such as liquid silicone rubber and electronic sealant, add them at a total mass of 2.0-8.0 ppm and mix thoroughly.


 b、 When preparing organic silicone release agents, pressure-sensitive adhesives, and other raw materials, add 100-150ppm according to the formula and mix well; 

        
 Mix component A and component B with added catalyst in proportion, and after thorough mixing, carry out molding processing according to the actual molding process.


 Suggested curing conditions are: 120 ℃/180-300s, or adjusted according to the formula.


 The optimal catalyst addition ratio and curing conditions should be determined based on different products and production processes.
 
 Storage conditions: Store at low temperature of 10-20 ℃, sealed, and away from light. Do not mix and store with strong oxidants, rubber, high-temperature adhesives, compounds containing nitrogen sulfur and phosphorus, heavy metal substances, etc.
 
  quality guarantee period: Under the above storage conditions, the shelf life is 6 months. If it exceeds the storage period, catalytic activity testing is required before use.


 matters needing attention:


 1. Platinum catalysts should be stored separately from strong oxidants to avoid contact with organic compounds such as N, P, S, as well as compounds such as Sn, Pb, Hg, As, and other heavy metal substances.


 2. Store at low temperature of 10-20 ℃, sealed, and away from light.


 3. When using, the catalyst should be thoroughly mixed with component A (non Si-H component) first, and then mixed with component B, otherwise it may cause uneven reaction.
