3-Aminopropiltrietoxissilano

O 3-Aminopropiltrietoxissilano (CAS 919-30-2) é um líquido incolor a levemente amarelado, de odor característico e volatilidade moderada, com ponto de ebulição típico em torno de 250 °C à pressão atmosférica. Trata-se de um silano funcionalizado, classificado quimicamente como um agente de acoplamento organossilânico, contendo grupos reativos amino e alcoxi em uma mesma molécula. É amplamente empregado como intermediário químico na síntese de adesivos, selantes, revestimentos e compósitos avançados, atuando como ponte entre fases orgânicas e inorgânicas para melhorar a aderência, a estabilidade térmica e as propriedades mecânicas dos materiais. Suas aplicações industriais concentram-se principalmente nos setores de revestimentos anticorrosivos, elastômeros de silicone, plásticos reforçados com carga mineral e formulações de tintas e vernizes de alto desempenho.

3-Aminopropyltriethoxysilane(gamma-Aminopropyltriethoxysilane) is a versatile amino-functional coupling agent used over a broad range of applications to provide superior bonds between inorganic substrates and organic polymers. The silicon-containing portion of the molecule provides strong bonding to substrates. The primary amine function reacts with a wide array of thermoset, thermoplastic, and elastomeric materials.Silane coupling agent 3-Aminopropyltriethoxysilane is applied in plastic products (including cables, glassfiber-reinforcement plastics etc.), rubber products, adhesives, coatings, pigments dispersion, inks, magnetic materials (plastic magnet and rubber magnet), metallic casting resins and resins concrete, etc.3-Aminopropyltriethoxysilane maximizes the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate, and a host of other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix are also improved.3-Aminopropyltriethoxysilane improves adhesion between magnetic powder and organic resins and dispersion of magnetic powder inorganic resins. Also these magnetic appliances attain higher magnetic orientation and excellent magnetic properties, higher mechanical strength, good processability, excellent weathering resistance.In glass-reinforced thermoset plastics, 3-Aminopropyltriethoxysilane enhances the flexural, compressive, and interlaminar shear strengths before and after exposure to humidity. 3-Aminopropyltriethoxysilane greatly improves wet electrical properties.With nitrile, polysulfide, expoxy, urethane, and adhesives and sealants, 3-Aminopropyltriethoxysilane improves pigment dispersion and maximizes adhesion to glass, aluminum, and steel.When 3-Aminopropyltriethoxysilane(gamma-Aminopropyltriethoxysilane) is used, glass-reinforced thermoplastics, polyamides, polyesters, and polycarbonates exhibit increased flexural and tensile strengths before and after wet exposure.In glass fiber and mineral wool insulation, as a phenolics resin binder additive, 3-Aminopropyltriethoxysilane imparts moisture resistance and allows recovery after compression.In shell molding foundry applications, 3-Aminopropyltriethoxysilane(gamma-Aminopropyltriethoxysilane) strengthens the bond between the phenolics binder and foundry sand.In grinding wheels, 3-Aminopropyltriethoxysilane promotes an improved, water-resistant bond between the abrasive grit and phenolics resin binder.3-Aminopropyltriethoxysilane(gamma-Aminopropyltriethoxysilane) is an excellent adhesion prompter in urethane, epoxy, and acrylic latex coatings, adhesives, and sealants.
