1,3,5,7-Tetramethyl-1,3,5,7-tetravinylcyclotetrasiloxane

1,3,5,7-Tetramethyl-1,3,5,7-tetravinylcyclotetrasiloxane (CAS 2554-06-5), commonly abbreviated as TTCS, is a cyclic siloxane monomer carrying four reactive vinyl groups. These vinyl functionalities make it a practical building block for hydrosilylation-curable silicone systems.

It serves as an essential crosslinker in silicone polymer networks. In silicone rubber and elastomer manufacturing, TTCS acts as a multifunctional crosslinker, enabling controlled network density in molded and extruded silicone parts.

Coatings formulators incorporate it into release coatings and conformal coatings where precise cure response and surface energy control are required. Adhesive and sealant producers use it to tune mechanical properties.

This is particularly useful in addition-cure silicone formulations where flexibility and thermal stability are design targets. It also functions as a surface-modifying agent in silane coupling systems for industrial use.

The material improves adhesion between silicone matrices and inorganic substrates such as glass or mineral fillers. TTCS is supplied as a clear liquid, typically at high purity grades suited for reactive silicone applications.

Standard commercial offerings include technical-grade and high-purity research grades, with purity specifications commonly ranging from 95% to 98%+. Packaging options generally range from small laboratory quantities.

Supply is available up to drum-scale for industrial processors. The product meets rigorous industrial requirements for consistency and performance in high-demand chemical manufacturing environments.
