CAS No.: 78-08-0

Properties: The use of GENIOSIL® GF 56 as a co-monomer in polymers results in binders which, among other advantages, exhibit much improved wet scrub resistance and abrasion resistance thanks to crosslinking and better adhesion to the substrate. Silane-modified thermoplastics obtained by grafting with GENIOSIL® GF 56 can be processed further using standard techniques. On exposure to moisture (e.g. water bath, climatic chamber), the silyl groups condense (ethanol is released) and function as crosslinking and/or adhesion points. By treating fillers with GENIOSIL® GF 56, mineral filled polymers can be obtained which exhibit improved mechanical and electrical properties. In addition, the particles are rendered strongly water repellent, which results in improved filler dispersibility and thus facilitates processing. Organic surface coatings will adhere more strongly to inorganic substrates that have been treated with GENIOSIL® GF 56. As a result, these coatings demonstrate markedly greater scratch resistance and resistance to chemicals.

Special features: GENIOSIL® GF 56 is an alkoxy vinyl silane. It´s a clear, colorless liquid with a characteristically aromatic odor.It hydrolyzes in the presence of moisture (ethanol is released) to form silanols, which can then react with themselves to produce siloxanes .As a bifunctional molecule, GENIOSIL® GF 56 is able to function as a molecular bridge between organic and inorganic substrates.

Application: GENIOSIL® GF 56 is used in the production of silane modified polymers that serve as binders in paints and adhesives. GENIOSIL® GF 56 is also used in the manufacture of pipes and cables made of silane crosslinked polyethylene (PE-Xb). In addition, GENIOSIL® GF 56 serves as an adhesion promoter in primers and coatings, and is used in the production of organically modified fillers for cable insulation.
