EVONIK SILANES

aqueous oligomeric aminoalkyl- and vinylbenzylaminofunctional silane hydrolysate with multifunctional properties – VPS 2978 is an aqueous oligomeric multifunctional product, that contains reactive secondary amino groups, reactive styrenic double bonds, antistatic cationic centers, and reactive silanol groups. The multifunctional nature of its reactivity enables VPS 2978 to bind and interact with inorganic and organic substrates, thus functioning as an adhesion promotor and surface modifier. VPS 2978 is a slightly yellow to darker yellow-orange liquid. It is easily dilutable in water, while pH value is already acidic and does not need specific control.

Epoxy functional silane resin – VPS 4721 is a bifunctional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows VPS 4721 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter, crosslinking agent, and/or surface modifier. VPS 4721 is a colorless liquid. It is soluble in alcohols, ketones, and aliphatic or aromatic hydrocarbons.

Modified organofunctional silane oligomer – VPS SIVO 260 is a novel multifunctional siloxane adhesion promoter with aminofunctionalities that can be used for various applications. VPS SIVO 260 is soluble in alcohols, aliphatic and aromatic hydrocarbons, but it can undergo reactions with ketones or ester solvents.

Modified organofunctional silane oligomer – VPS SIVO 280 is a novel multifunctional siloxane adhesion promoter with aminofunctionalities that can be used for various applications. VPS SIVO 280 is soluble in alcohols, aliphatic and aromatic hydrocarbons, but it can undergo reactions with ketones or ester solvents.

Oligomeric propyl siliconate as hydrophobing agent – Dynasylan 608 is an oligomeric propyl siliconate; Clear colourless liquid; approx. 55% active ingredient; water based, VOC free; pH >13; non-flammable. VPS SIVO 608 is a strong hydrophobing agent that can be applied to inorganic substrates. It can be used pure or in diluted form, in such solvents as alcohol.
