Products in Paints & Coatings: Silicates

Dynasylan® SILBOND® Condensed serves as a raw material composed of tetraethyl orthosilicate (TEOS; Si[OEt]4 ). This substance is utilized for acid- or alkali-catalyzed hydrolysis and subsequent condensation reactions, commonly known as the sol-gel process. The rate of gelation is influenced by the concentration of water and the pH.

Dynasylan® SILBOND® HT-28A is a milky-white, low-viscosity pre-hydrolyzed ethyl polysilicate hybrid binder, boasting a silica content ranging from 32.5 to 33.5% (as SiO2 ). This silica content arises from a blend of TEOS-derived silica and other components. This formulation is tailored for use in two-component inorganic zinc-rich primers. The product brings forth enhanced toughness and exceptional performance in high-temperature scenarios. The heightened toughness results directly from the increased silica content in contrast to an ethyl polysilicate binder.

Dynasylan® SILBOND® 40 is an ethyl polysilicate, emerges from partial hydrolysis of tetraethyl orthosilicate (TEOS). This transformation converts ethoxy groups into hydroxyl groups, generating silanols. Subsequent condensation of silanols engenders siloxane bonds (-Si-O-Si-O-) and prompts eventual gelation. Often deployed as an intermediary, Dynasylan® SILBOND® 40 undergoes further hydrolysis to produce a binder suitable for diverse applications. These include inorganic zinc-rich primers, investment casting molds, ceramic shapes, coatings, and thermal insulation.

Dynasylan® SILBOND® HT-33 is a milky-white, low-viscosity pre-hydrolyzed ethyl polysilicate hybrid binder, boasts a silica content ranging from 32.7% to 34.0% (as SiO2). Formulated for two-component inorganic zinc-rich primers, this material brings about improved toughness and exceptional performance in high-temperature applications. The elevated SiO2 content directly contributes to its enhanced toughness.

Dynasylan® A is also known as TEOS (tetraethoxysilane), is the ethyl ester of orthosilicic acid. This colorless, low-viscosity liquid boasts a SiO content of 28.5%. Utilization involves acid- or alkali-catalyzed hydrolysis, leveraging all four ethoxy groups for reaction and earning it tetrafunctional status. Hydrolysis initiates silanol group formation, which further condenses to establish robust siloxane bonds (-Si-O-Si-). Notably, condensation begins before hydrolysis concludes, with ongoing condensation during storage resulting in gel formation. Gelation rate hinges on water concentration.
