SiSiB® PC5423

Ethyl Polysilcate 32.
Synonym: Ethyl Silicate 32

Chemical Structure


Introduction

SiSiB® PC5423 is a hydrolyzed and oligomerized form of ethyl silicate. It is a mixture of monomers, dimers, trimers and cyclic polysiloxanes. SiSiB® PC5423 is a transparent liquid containing 32% silica (SiO2) by mass, but in practice, in addition to chain condensates, it also contains branch-shaped and ring-shaped condensates.

Applications

SiSiB® PC5423 is used to deposit silicic acid formed as a result of complete hydrolysis.The resulting silicic acid bonds well to many inorganic substrates, such as ceramic, fillers, glass, metal, pigments and synthetic fibers. The deposition of a thin SiO2 layer improves the chemical and the thermal stability and mechanical properties.


SiSiB® PC5423 can be used as a binder in zinc-rich (corrosion resistant) coating.


SiSiB® PC5423 can be used as a starting material for sol-gel process.


SiSiB® PC5423 can be used as a crosslinker component in cold curing silicone rubber systems.


SiSiB® PC5423 can be used as a hardening component in dentistry for impression materials and as binder for embedding material.


SiSiB® PC5423 can be used as a binder in precision foundry industry.
