SF-H560 is an epoxy-functionalized organosilane with a bifunctional structure that incorporates both an epoxy group and a hydrolyzable inorganic methoxysilyl group. This structure grants SF-H560 exceptional versatility, allowing it to bond inorganic materials (such as metals, glass, and ceramics) with organic polymers (including thermoplastics, thermosets, and elastomers), making it an effective coupling agent, adhesion promoter, crosslinking agent, and surface modifier.

• Epoxy Group: The epoxy group is reactive with a variety of resins, including epoxy resin, phenolic resin, polyurethane, and acrylic resins. It plays a role in chemical crosslinking and enhancing adhesion between polymers and inorganic surfaces.
• Methoxysilyl Group: This group can hydrolyze in the presence of moisture to form silanol groups (Si-OH), which are highly reactive with hydroxyl groups on inorganic substrates, facilitating the formation of durable bonds between inorganic materials and resins.
• Hydrolyzable Properties: The methoxy groups of SF-H560 can hydrolyze in the presence of water, leading to the formation of silanol groups that can condense with hydroxyl groups on inorganic surfaces (like glass, fiberglass, quartz, and metals). This process is important for ensuring strong adhesion and compatibility between inorganic and organic materials.
• Catalysis by Organic Acids: The hydrolysis reaction can be accelerated by the presence of organic acids (e.g., acetic acid), improving the efficiency of bonding in the presence of water.

SF-H560 is primarily used in applications where bonding between organic and inorganic materials is required, including:

1. Adhesion Promotion: It improves the adhesion between inorganic substrates (such as glass, metal, or minerals) and organic resins or coatings, making it ideal for use in industries like coatings, composites, and adhesives.
2. Surface Modification: SF-H560 is used to modify the surface properties of inorganic materials, improving their compatibility with organic polymers.
3. Dispersant in Composite Materials: It is used to improve the dispersion and bonding of inorganic fillers, such as mineral powders and fibers, in polymer matrices, enhancing the mechanical and thermal properties of composites.
4. Crosslinking Agent: SF-H560 can serve as a crosslinking agent in resin formulations, improving the physical properties of the final product, such as durability, strength, and resistance to environmental factors.

• SF-H560 is a colorless, low-viscosity liquid with a slight rosin-like odor.
• It is soluble in alcohols, ketones, aliphatic hydrocarbons, and aromatic hydrocarbons, making it versatile for incorporation into a range of solvent-based formulations.

SF-H560 is compatible with a variety of resins, including:

• Epoxy resin
• Phenolic resin
• Polyurethane
• Acrylic resin
• Polysulfide rubber These materials can be enhanced in terms of bonding and compatibility with inorganic fillers and substrates when treated with SF-H560.

SF-H560 is a versatile epoxy silane coupling agent that enhances the adhesion, surface modification, and crosslinking of organic and inorganic materials. Its ability to form strong chemical bonds between these materials makes it essential in composite manufacturing, coatings, adhesives, and other industrial applications where improved material compatibility and performance are required.

SF-X570/174 is a reactive chemical with methacrylic-based organic functional groups and trimethoxysilyl-based inorganic functional groups. This bifunctional group structure gives SF-X570 special properties: it can organically bond inorganic materials (such as glass, silica) and organic thermosetting resins to promote adhesion, crosslinking agents and / or the role of surface modifiers. It is a colorless and transparent liquid that is sensitive to light and heat, has a clear sweet smell, soluble alcohols, aliphatic or aromatic hydrocarbons.

Applications

Treatment of glass fiber yarn with a wetting agent containing SF-X570 silane coupling agent (containing film-forming agent, lubricant and antistatic agent) can increase the mechanical strength of this glass fiber yarn-reinforced composite material. SF-X570 can improve the wet and dry mechanical strength of polyester composites filled with silica, glass, silicate and metal

oxides.

SF-X570 can improve the wet electrical properties of many inorganic filler filled composites.

SF-X570 can be copolymerized with vinyl acetate and acrylate or methacrylate monomers to synthesize silane-based polymers that can be cross-linked and cured at room temperature. These silylated polymers are widely used in coatings, adhesives and sealants. Provides excellent adhesion and durability.

SF-X570 silane can be applied to inorganic surfaces in the form of a diluted aqueous solution (0.1 to 0.5% silane). When preparing an aqueous solution, adjust the pH of the water to 3.0 to 4.5 with acetic acid, then add silane while stirring well.
