Component Specifications

Definition
Catalysts for silicone resin are chemical agents, typically organometallic compounds or acids, that lower the activation energy of crosslinking reactions between siloxane chains, enabling faster curing at lower temperatures. They are crucial in controlling the polymerization rate and final properties of the resin.
Working Principle
Catalysts provide an alternative reaction pathway with lower activation energy. In silicone resin, they facilitate the condensation or addition reactions between silanol (Si-OH) and alkoxy (Si-OR) groups, or hydrosilylation between Si-H and vinyl groups, forming a three-dimensional network.
Materials
Common catalysts include tin compounds (e.g., dibutyltin dilaurate), platinum complexes (e.g., Karstedt's catalyst), titanium chelates, and organic acids (e.g., p-toluenesulfonic acid).
Technical Parameters
  • Density 0.9-1.2 g/cm³
  • Viscosity 10-100 cP at 25°C
  • Flash Point >100°C
  • Active Content 95-99%
Standards
ISO 9001, ASTM D2369
