What are reactive silicones?
What are reactive silicones?
Reactive silicone polymers are a series of silanol functional fluids with various viscosities and silanol contents. Reactive silicone polymers are useful in the treatment of fillers and as Anti-Structuring additives in high consistency silicone rubber and silicone Room Temperature Vulcanizing (RTV) formulations.
What is epoxy silane?
Epoxy silanes are bifunctional organosilanes whose molecules consists of a reactive epoxy group and a hydrolysable alkoxy group. As the main series of silane coupling agents, epoxy silanes have the same capabilities to promote adhesion between organic polymers and inorganic materials.
What is silane coupling agent?
Silane coupling agents are compounds whose molecules contain functional groups that bond with both organic and inorganic materials. A silane coupling agent acts as a sort of intermediary which bonds organic materials to inorganic materials.
How does a silane coupling agent work?
Silane coupling agents, which are synthetic hybrid inorganic-organic compounds, are used to promote adhesion between dissimilar materials. After this treatment, a silica layer is formed on the surface so that the silane coupling agent can react chemically to form a durable bond with non-silica-based materials.

How is silanol used in an acetoxy system?
The silanol is in essence displaced by the silane. This is depicted below for an acetoxy system. The silicone now has two groups at each end that are extremely susceptible to hydrolysis. The silicone is stored in this form and protected from moisture until ready for use.
How are terminal silanol groups produced in gelest?
Terminal silanol groups render polydimethylsiloxanes susceptible to condensation under both mild acid and base conditions. They are intermediates for most room temperature vulcanizable (RTV) silicones. Low molecular weight silanol fluids are generally produced by kinetically controlled hydrolysis of chlorosilanes.
