DYNASYLAN 1189

DYNASLYAN 1189 is a bifunctional silane coupling agent that possesses reactive secondary amine and hydrolyzable methoxysilyl groups. This dual reactivity of DYNASYLAN 1189 allows it to chemically bond to both inorganic materials and organic polymers, functioning as an adhesion promoter or surface modifier. DYNASYLAN 1189 can provide improvements in processing properties, such as adhesion, filler dispersion, and rheological behavior. It can be used as a primer or additive for improving the adhesion of paints and coatings to substrates. It can be used as a size constituent or finish for glass fiber/glass fabric composites, as an additive to phenolic, furan and melamine resins used in foundry resins, as a primer or additive and for the chemical modification of sealants and adhesives, for pretreatment of fillers and pigments used in mineral-filled polymers, and as a primer and additive for improving the adhesion of paints and coatings to substrates.
