Products in Wire & Cable: Silanes

WACKER® Primer G 790 Toluene Free is a solution of reactive siloxanes and silanes in an organic solvent. It is specifically formulated to be free of toluene and other aromatic solvents. The primer can be applied directly to the substrate or diluted if desired. As the solvent evaporates and when exposed to ambient humidity, the primer forms a rigid film that firmly adheres to the substrate. By applying a silicone rubber onto the primed substrate and subsequently vulcanizing it, a strong bond is achieved between the silicone rubber and the substrate.

GENIOSIL® XL 10 is an alkoxyvinyl silane compound. When exposed to moisture, the silane undergoes hydrolysis, resulting in the release of methanol.

The applications of GENIOSIL® XL 10 include marine and protective coatings, plastic additives, and plastic crosslinking.

GENIOSIL® GF 56 is an alkoxyvinylsilane. It is a clear, colorless liquid with a distinctive aromatic odor.

Acting as a bifunctional molecule, GENIOSIL® GF 56 serves as a molecular bridge between organic and inorganic substrates.

WACKER® Primer G 790 is a solution containing reactive siloxanes and silanes dissolved in an organic solvent. This primer can be directly applied to the substrate or can be diluted if needed. As the solvent evaporates and when exposed to atmospheric humidity at room temperature, the primer forms a rigid film that firmly adheres to the substrate. By applying a silicone rubber onto the primed substrate and subsequently vulcanizing it, a strong bond is achieved between the silicone rubber and the substrate.

ELASTOSIL® AUX G 800 is a solution of reactive siloxanes and silanes in an organic solvent. The primer composition can be applied to the substrate as-is or diluted. During evaporation of the solvent and on exposure to atmospheric humidity at ambient temperature, a rigid primer film is formed that firmly adheres to the substrate. Application of silicone rubber onto the primed substrate and subsequent vulcanization will then result in a tight bond between the silicone rubber and the substrate.

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.
