EVONIK SILANES

Polyethyleneglycol-functional alkoxysilane – Dynasylan 4148 is a ready-for-use silane and is soluble in water and most organic solvents. Contrary to most other organofunctional silanes, Dynasylan 4148 features chemical polarity yet remaining chemically not reactive. Such a product is used as a hydrophilic compatibilizer rather than a covalent adhesion promoter.

Polyethyleneglycol-functional alkoxysilane – Dynasylan 4150 is a non-ionic, ready-to-use silane, soluble in water and most organic solvents. Contrary to most other organofunctional silanes, Dynasylan 4150 features chemical polarity yet remaining chemically not reactive. Such a non-coupling filler or pigment surface-modifier silane is used as a hydrophilic compatibilizer rather than as a covalent adhesion promoter.

Reactive vinyl siloxane oligomer, methoxy functional – Dynasylan 6490 is a vinyl silane concentrate (oligomeric siloxane) containing vinyl and methoxy groups. Dynasylan 6490 is a colourless, nearly odorless low-viscosity liquid. Dynasylan 6490 is an excellent compatibiliser between inorganic fillers (e.g. kaolin, MDH, ATH) and organic polymers (e.g. EPDM, EVA, PE).

Vinyl silane concentrate (oligomeric siloxane) – Dynasylan 6498 is a vinyl silane concentrate (oligomeric siloxane) containing vinyl and ethoxy groups. Dynasylan 6498 is a colourless, nearly odorless low-viscosity liquid. Dynasylan 6498 is an excellent compatibiliser between inorganic fillers (e.g. kaolin, MDH, ATH) and organic polymers (e.g. EPDM, EVA, PE).

Reactive vinyl-alkyl siloxane oligomer, ethoxy functional – Dynasylan 6598 is an oligomeric siloxane containing vinyl, propyl and ethoxy groups. Dynasylan 6598 is a further development of Dynasylan VTMOEO, vinyl-tris(2-methoxy-ethoxy)silane. Dynasylan 6598 is a colourless, nearly odorless low-viscosity liquid.
