The Catalyst That Redefines Silicone Processing

Platinum(0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane, or IOTA-8100, is a game-changer in silicone chemistry. With its unique molecular structure and a molecular weight of 381.48, this catalyst is the driving force behind numerous silicone-based innovations. Its CAS number, 68478-92-2, and EINECS identifier, 270-844-4, further underscore its significance in the scientific community.

The Science of Efficient Catalysis

IOTA-8100's light yellow liquid form, coupled with its physical properties—a melting point of 12-13°C, a boiling point of 138°C, a flash point of 30°C, and a specific gravity of 0.984g/mL at 25°C—make it an excellent choice for silicone processing. Its active content, exceeding 20%, ensures rapid catalysis, with a room temperature activity of ≤10 minutes and full cure at 120°C within 25 minutes. This catalyst's specificity for vinyl siloxane and hydrogen siloxane cross-linking reactions underscores its efficacy in silicone formulations.

Customizable Solutions for Precision Applications

With customizable concentrations ranging from 500ppm to 40,000ppm, IOTA-8100 can be tailored to meet the most demanding requirements. In the rubber industry, it serves as a vital vulcanizer and catalyst for mixing molding rubber, silicone tube extrusions, and pacifier glue. Its ability to catalyze the cross-linking of silicone oils and rubbers makes it indispensable in formulating pouring sealants, silicone sheets, mold glues, RTV-M, silicone inks, silicone resins, and more.
