Evonik (formerly Degussa AG) 1189, organic silane coupling agent Dynasylan 1189, N - (n-butyl) - γ - aminopropyltrimethoxysilane Overview:
Dynasylan®1189 N - (n-butyl) -3-aminopropyltrimethoxysilane is developed and produced by Evonik Degussa AG, and is a bifunctional silane with both active secondary amino groups and hydrolyzable methoxy groups. Its dual reactivity can enable Dynasylan ® one thousand one hundred and eighty-nine N - (n-butyl) -3-aminopropyltrimethoxysilane combines inorganic materials (such as glass, metal, fillers) and organic polymers (such as thermosetting plastics, thermoplastic plastics, and elastomers) through chemical bonds. The product is often used as an adhesion promoter or surface modifier.
Dynasylan®1189 N - (n-butyl) -3-aminopropyltrimethoxysilane is colorless or pale yellow, with a slight ammonia odor, and is soluble in alcohol, aliphatic or aromatic hydrocarbon solvents.
Dynasylan ® 1189 N - (n-butyl) -3-aminopropyltrimethoxysilane functional:
Dynasylan ® 1189 in the presence of water The methoxy group of N - (n-butyl) -3-aminopropyltrimethoxysilane can be hydrolyzed to generate reactive silanol groups that bind to various inorganic materials. And Dynasylan ® one thousand one hundred and eighty-nine The n-butyl amino functional group at the lipophilic end can react with suitable polymers.
Dynasylan®1189 The hydrolysis of N - (n-butyl) -3-aminopropyltrimethoxysilane in water catalyzed by acid (such as acetic acid, pH 3) needs to be carried out. To make Dynasylan ® one thousand one hundred and eighty-nine Dissolve in organic solvents according to Dynasylan ® one thousand one hundred and eighty-nine The addition amount of N - (n-butyl) -3-aminopropyltrimethoxysilane is 2-4% Mix the water into the solvent and stir for 5 hours before use.
Suitable inorganic substrates include materials such as glass, glass fiber, glass felt, wollastonite, and kaolin.
Dynasylan ® 1189 N - (n-butyl) -3-aminopropyltrimethoxysilane is suitable for organic systems such as epoxy resin, polyurethane, PA, PBT, EVA, modified PP, and silicone resin.
Especially in the application of thermoplastic materials, Dynasylan ® 1189 N - (n-butyl) -3-aminopropyltrimethoxysilane is a highly effective coupling agent that enhances MAA Modified PE, polypropylene resin, and polyamide can achieve excellent mechanical properties. Dynasylan®1189 N - (n-butyl) -3-aminopropyltrimethoxysilane is particularly helpful in improving the impact resistance of polyamides. Under harsh application conditions, use Dynasylan ® Glass fibers and fillers treated with 1189 N - (n-butyl) -3-aminopropyltrimethoxysilane exhibit superior performance compared to those treated with ordinary aminosilane. Dynasylan ® 1189 N - (n-butyl) -3-aminopropyltrimethoxysilane can also be used as a capping agent for polyurethane.
