Evonik (formerly Degussa AG) 1122, organic silane coupling agent Dynasylan 1122, bis - (3-triethoxysilylpropyl) Overview:
Dynasylan® 1122 Bis - (3-triethoxysilylpropyl) amine is developed and produced by Evonik Degussa AG, and can be used as an adhesion promoter between inorganic materials (such as glass, metal, and fillers) and organic polymers (thermosetting materials, thermoplastic plastics, and synthetic rubber). It can also be used as a surface modifier for chemical modification of substrates.
Dynasylan® 1122 Bis - (3-triethoxysilylpropyl) amine is a light yellow liquid with an ammonia like odor. Easily soluble in alcohols, aliphatic or aromatic hydrocarbons.
Dynasylan ® 1122 bis - (3-triethoxysilylpropyl) amine functionality:
Dynasylan® 1122 Bis - (3-triethoxysilylpropyl) amine is a bifunctional organic compound. In the presence of water, its ethoxysilane group undergoes hydrolysis to generate active silanol groups, which can bond to inorganic materials. The amino groups of organic compounds can interact with suitable polymers. Due to the presence of six hydrolyzable substituents in one molecule, Dynasylan ® 1122 is particularly suitable for forming highly cross-linked network structures on or between substrates and organic matrices.
Dynasylan® 1122 The hydrolysis of bis - (3-triethoxysilylpropyl) amine in water requires the action of acidic catalysts (such as formic acid or acetic acid to adjust the pH to 2-3). To achieve solubility in organic solvents, each serving of Dynasylan ® one thousand one hundred and twenty-two Bis - (3-triethoxysilylpropyl) amine requires the addition of 2-4% (by weight) of water. The solution needs to be stirred for 5 hours before use.
Suitable inorganic substances can be glass, glass fiber, glass wool, asbestos, silicic acid, quartz, sand, quartz, calcium silicate, mica; It is also suitable for aluminum hydroxide, kaolin, talc powder, other silicate fillers, metal oxides, and metals. Suitable polymers include epoxy resin, polyurethane, phenolic resin, furan resin, and melamine resin PA、PBT、PC、EVA， Modified PP, PVB, PVAC, PVC, acrylic ester, and silicone organic resin.
Dynasylan® 1122 The secondary amine group in bis - (3-triethoxysilylpropyl) amine endows it with high alkalinity, and compared to the primary amine group, its reactivity is lower. This has the following benefits for polymer systems using silane, such as in adhesives and sealants: uniform distribution of silane, unless continuing to bond organic materials (such as polymers), Dynasylan ® one thousand one hundred and twenty-two The bonding or network structure between bis - (3-triethoxysilylpropyl) amine and inorganic fillers will not begin. In addition, Dynasylan ® 1122 has been successfully applied as a component in water-based PA - and PU coatings for the treatment of glass fibers.
Evonik (formerly Degussa AG) 1122, organic silane coupling agent Dynasylan 1122, bis - (3-triethoxysilylpropyl):
Dynasylan® 1122 Bis - (3-triethoxysilylpropyl) amine is an important additive used in many fields, such as:
• Fiberglass, Fiberglass Composite: A component used for post-treatment or coating treatment
• Pre coating for metals
• Additives used as phenolic resin adhesives in asbestos insulation materials and abrasives
• Mold resin: as an additive for phenolic, furan, and melamine resins
• Sealing glue and adhesive: pre coating, additives
• Pre treatment of fillers and pigments in mineral filled polymers (composite materials) or HFFR cables
• Paint and coatings: used as additives and pre coatings to improve adhesion to substrates
Using Dynasylan ® The most important role of 1122 is:
Improve product performance, such as:
• Bending strength, tensile strength, impact strength, and elastic modulus
• Improve water resistance and corrosion resistance
• Improve operational performance, for example:
• adhesion
• Better dispersion of fillers
• Rheological properties: reduce viscosity
