The dual nature of its reactivity allows Dynasylan® 2201 EQ 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 and as a surface modifier. Dynasylan® 2201 EQ is a 50% solution of silane in methanol, is a colorless-yellowish liquid with an alcohol-like odor and is soluble in alcohols, ketones, esters or aromatic hydrocarbons.
Due to novel patented process, Dynasylan® 2201 EQ is the first ureidofunctional silane, which contains no carcinogenic by-products, e.g. ethylcarbamate. Dynasylan® 2201 EQ is therefore not classified as "carcinogenic, class 2".
Typical Applications
Dynasylan® 2201 EQ finds application in the products of many industries.
