迈图硅烷偶联剂是一系列具有优异性能的化学助剂，在多个工业领域应用广泛。
type
Momentive has a wide range of silane couplings, including aminosilane couplings (such as A-1100, A-1120, etc.), ureasilane coupling agents (such as A-1160, A-1524, etc.), epoxy silane coupling agents (such as A-187, WETLINK78, etc.), sulfur/mercaptosilane coupling agents (such as A-189, A-LINK599, etc.), methacryloyloxysilane coupling agents (such as A-174, COATOSIL-1757, etc.), etc.
performance characteristics
activity and strong adhesion: The molecular activity is strong, and it can react with a variety of organic resins and inorganic substrates to form covalent bonds with strong bonding and significantly improve interfacial adhesion. For example, A-1100 can greatly improve the wet and dry bending strength and tensile strength of glass fiber reinforced plastics.
: Some products can be stable in water without compromising performance for long periods of time, such as CoatOSil MP200, which is easy to use in a variety of formulations.
improve material properties: It can improve the dispersion of fillers in the matrix, improve the processability of materials, and also enhance the wear resistance, chemical resistance, aging resistance of materials, etc., such as Silquest A-Link™ 235 can effectively improve the tensile strength and elasticity of materials.
application area
adhesives and sealants: As bonding promoters, they improve the adhesion and durability of adhesives to substrates such as glass, metal, and ceramics, such as A-1100 can be used in adhesives such as polyurethane and epoxy.
Composites: Used for glass fiber reinforced plastics, mineral filler filled resins, etc., to improve the physical and mechanical properties of composite materials, such as A-1120 can be used in clay-reinforced natural rubber and nitrile rubber, etc.
coatings: improve the adhesion of coatings to substrates, scrub resistance and weather resistance, suitable for industrial coatings, water-based industrial coatings, etc., such as CoatOSil MP200 can be used for water-based acrylic emulsions, water-based wood paints, etc.
Plastics & Rubber: Improve the processability and physical properties of plastics and improve the adhesion of rubber to inorganic materials, such as A-174 for unsaturated polyester composites and A-2387 for low rolling resistance tire formulations.
