Product Details

Dynasylan® 1189 possesses a reactive secondary amine and hydrolyzable methoxysilyl groups. The dual nature of its reactivity allows Dynasylan® 1189 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics and elastomers) thus functioning as an adhesion promoter or as a surface modifier and can be used for the chemical modification of substances. Dynasylan® 1189 is a colorless to slightly yellowish liquid with a light amine ­like odor which is, for example, soluble in alcohols, and aliphatic or aromatic hydrocarbons.
