Evonik (formerly Degussa AG) 1175, organic silane coupling agent Dynasylan 1175, N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane Overview:
N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane (Also known as:Silane coupling agent 1175,Thickener 1175）Developed and produced by Evonik Degussa AG, this active ingredient contains 40% hydrogen chloride and silane
Dynasylan ® 1175 N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane is a cationic amino functional silane with hydrolyzable inorganic methoxysilane groups. Its dual reactivity enables it to form chemical bonds with inorganic materials (glass, metal, fillers) and organic polymers (such as thermosetting plastics, thermoplastic plastics, synthetic rubber), making it suitable as an adhesion promoter and surface modifier.
Dynasylan ® 1175 N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane is a dark yellow to brown liquid containing 40% silane in methanol solution.
Dynasylan ® 1175 N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane is miscible with water and undergoes hydrolysis reaction.
Dynasylan ® 1175 N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane functionality:
Dynasylan® 1175 N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane undergoes hydrolysis of the methoxy group in Dynasylan ® 1175 in the presence of water, forming active silanol groups that can bond to many inorganic substrates. The cationic amino groups of the organophilic substance of Dynasylan ® 1175 N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane can react with suitable polymers. Because of Dynasylan ® 1175 not only contains amino groups but also reactive vinyl groups, which can react with polymers that react with amino groups and polymers containing free radicals.
Its cationic structure gives it anti-static properties. In many applications, it can have a very good resin wetting effect. In addition, it can immediately dissolve with water, even water with a pH of 7. Because of its high chlorine content, it can prolong the gel time of epoxy resin. Therefore, it is not easy for air to remain in the resin.
Dynasylan ® 1175 N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane is best hydrolyzed in the presence of acetic acid (pH 3-4).
Suitable inorganic substances can be glass, glass fiber, glass wool, asbestos, silica, quartz, sand, quartz, calcium silicate, mica; It is also suitable for aluminum hydroxide, kaolin, talc powder, other silicate fillers, metal oxides, and metals.
Dynasylan ® 1175 N-vinylbenzyl-N '- aminoethyl-3-aminopropyl polysiloxane is suitable for polymers such as epoxy resin, methyl methacrylate, unsaturated polyester resin, and polyurethane PA、PBT、PC、EVA， Modified PP, PVB, PVAC, acrylic ester.
