Products

VPS 4721 is a bifunctional organosilane with 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 nearly colorless liquid. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.
