EVONIK SILANES

Ethyl polysilicates – Dynasylan SILBOND H-25 is a clear, low-viscosity pre-hydrolyzed ethyl polysilicate binder with minimum 24.5% silica (as SiO2).

Ethyl polysilicates – Dynasylan SILBOND H-4 is a clear, low-viscosity pre-hydrolyzed ethyl polysilicate binder that has been designed for the precision investment casting industry. The silica content ranges from 17.5% to 19.0% (as SiO2). It is well suited for use with alkaline refractories, and in ceramic shell and dip casting applications.

Ethyl polysilicates – Dynasylan SILBOND H-5 is a clear, low-viscosity pre-hydrolyzed ethyl polysilicate binder that has been designed for the precision investment casting industry. It contains a higher percentage (approximately 19.5%) silica content (as SiO2) and a lower acidity level than Dynasylan SILBOND H-4. It is well suited for use in block-casting applications.

Ethyl polysilicates – Dynasylan SILBOND H-6C is a clear, low-viscosity pre-hydrolyzed ethyl polysilicate binder that has been designed for use in two part zinc-rich primer systems. The silica content ranges from 17.5% to 19.0% (as SiO2). It can also be used for investment casting applications.

Ethyl polysilicate low / VOC hybrid binder – Dynasylan SILBOND HT-28A is a milky-white, low-viscosity pre-hydrolyzed ethyl polysilicate hybrid binder with content ranging from 32.5 to 33.5% silica (as SiO2). The silica content is resultant of a mixture of silica derived from TEOS and other components. This material is formulated for use in two component inorganic zinc-rich primers. Advantages include improved toughness and excellent performance in high-temperature applications. The improved toughness is a direct result of the higher silica content as compared to a ethyl polysilicate binder.
