SiSiB® PC5425 is a transparent liquid containing 50% silica (SiO2) by mass, but in practice, in addition to chain condensates, it also contains branch-shaped and ring-shaped condensates. It is a hydrolyzed and oligomerized form of ethyl silicate. It can be used as a binder in zinc-rich (corrosion resistant) coating, as a starting material for sol-gel process, as a crosslinker component in cold curing silicone rubber systems, as a hardening component in dentistry for impression materials and as binder for embedding material, or as a binder in precision foundry industry
SiSiB Silicones has more than 20 years’ experience in manufacturing various silicone materials. They have established six factories in China to manufacture organofunctional silanes (silane coupling agents, silane crosslinkers, silane blocking agents), silicone fluids (straight, modified), silicone rubbers (Gum, HTV, RTV and LSR), silicone resins and fumed silica.
SiSiB® silanes are widely used in adhesives and sealants to improve environmental resistance, increase adhesion and other mechanical properties and can be used to improve the adhesion of many coatings (urethanes, epoxies, phenolics and others) to glass and metal surfaces for the paint and coating industry.
