Ningbo Inno Pharmchem Co.,Ltd is a leading manufacturer and supplier of silane coupling agents, including the popular KH-572. Silane coupling agents are used to enhance the bonding between inorganic materials, such as glass, metal, and ceramics, and organic materials, such as plastics, adhesives, and coatings. The KH-572 silane coupling agent is a versatile and effective additive that can improve the mechanical, thermal, and chemical properties of various materials and products.

Chemical Properties of KH-572 Silane Coupling Agent

The KH-572 silane coupling agent has the chemical formula of 3-(methacryloxy)propylmethyldimethoxysilane, and its molecular weight is 248.4 g/mol. It has a clear and colorless liquid appearance, with a boiling point of 130-133°C and a density of 1.03 g/mL. Its refractive index is 1.429, and its viscosity is 2-5 cSt. The KH-572 silane coupling agent is soluble in most organic solvents, such as alcohols, ketones, and esters, but insoluble in water.

The KH-572 silane coupling agent contains a methacrylate functional group that can copolymerize with various monomers, such as acrylics, styrene, and vinyl acetate, to form a strong and durable bond. It also has two methoxy groups that can react with the hydroxyl groups of inorganic surfaces, such as silica, alumina, and titanium dioxide, to form a stable and covalent linkage. The KH-572 silane coupling agent can thus improve the adhesion, wetting, and dispersion of organic materials on inorganic surfaces, and vice versa.

Feasibility Analysis of KH-572 Silane Coupling Agent

The KH-572 silane coupling agent is a versatile and widely used additive in various industries, such as automotive, construction, electronics, and healthcare. It can enhance the performance and durability of many products, such as coatings, adhesives, sealants, composites, and plastics. Here are some examples of the feasibility of using KH-572 silane coupling agent in different applications.

1. Coatings: The KH-572 silane coupling agent can improve the adhesion and weatherability of coatings on metal, glass, and plastic substrates. It can also enhance the scratch resistance and chemical resistance of the coatings. For example, adding 2-5% KH-572 to an epoxy or acrylic coating can increase the adhesion strength by 50-100%, and reduce the water absorption and corrosion rate.

2. Adhesives and Sealants: The KH-572 silane coupling agent can improve the bonding strength and durability of adhesives and sealants on different surfaces, such as wood, concrete, and metal. It can also enhance the flexibility and toughness of the adhesives and sealants. For example, adding 1-3% KH-572 to a silicone or polyurethane adhesive can increase the lap shear strength by 50-200%, and improve the resistance to aging and moisture.

3. Composites: The KH-572 silane coupling agent can improve the interfacial adhesion and mechanical properties of composites made of inorganic fillers and organic resins, such as glass fiber reinforced plastics (GFRP) and carbon fiber reinforced plastics (CFRP). It can also enhance the dimensional stability and thermal conductivity of the composites. For example, adding 0.5-2% KH-572 to a polyester or epoxy resin can increase the tensile strength, flexural strength, and impact strength of the GFRP or CFRP by 30-100%.

4. Plastics: The KH-572 silane coupling agent can improve the processing and performance of various plastics, such as polyethylene, polypropylene, and polycarbonate. It can also enhance the adhesion and compatibility of different plastics, such as blending, grafting, and crosslinking. For example, adding 0.1-0.5% KH-572 to a polyolefin or polyester can increase the melt flow rate, tensile strength, and elongation at break of the plastic by 10-50%.
