application:
1. This product is used in the treatment of glass fiber, which can improve the mechanical strength of glass fiber reinforced composites, and has a high strength retention rate in the wet state.
2. This product is especially suitable for the surface treatment of fillers in epoxy matrix composites, such as epoxy resin type integrated electronic materials and printed circuit boards, which can improve the dispersion of fillers in polymers and improve the mechanical and electrical properties of composites.
3. This product can improve the adhesion of various adhesives, such as two-component epoxy adhesive, acrylic adhesive, polyurethane adhesive and epoxy paint, with glass, metal and other substrates.
4. This product is used in the coating industry, which can significantly improve the adhesion of the paint film to hydroxyl containing substrates on the surfaces of glass, metal, etc., and its water and dirt resistance
usage method:
When this product is used as an additive, the addition amount of silane is generally 0.5-3.0% of the formula amount, and the most appropriate amount needs to be determined through experiments. This product is especially suitable for applications where the environmental humidity is high.
Like other silanes, this product can be configured into an aqueous solution with a concentration of 0.1-1.0%. When preparing the aqueous solution, it is recommended to use organic acids such as acetic acid to adjust the pH of pure water to 3.0-4.5, and then add silane to the acidified water with stirring, and continue stirring until the hydrolysis reaction is complete, forming a clear, transparent and homogeneous solution. Since the prepared silane aqueous solution is unstable and will gradually form silane oligomers, it is recommended that the prepared silane aqueous solution be used within 24 hours. If turbid precipitation occurs during storage, the performance of silane aqueous solution will be affected and cannot be used.
The surface of inorganic materials can be treated with silane aqueous solution by spraying, coating, impregnation, etc. Silane can also be directly mixed with filler under high shear without adding any solvent.
After the surface of the filler is treated with silane, it can be dried by natural air or for a short time at a temperature of 105 to 120 ºC to complete the condensation of silanol groups on the surface and remove methanol and water. The best addition amount, use and drying conditions (such as time and temperature) for each application need to be obtained through experiments. This product will produce a small amount of low molecular alcohol in the reaction, so proper ventilation system should be considered for treatment in the production process.
Solubility:
This product is easy to hydrolyze and soluble in isopropanol, acetone, toluene, xylene, mineral oil and other organic solvents. Generally speaking, silane can be dissolved in many common organic solvents, but when using a specific solvent, the solubility and stability of silane in the solvent should be verified.
Application solution of sulfur-containing silane coupling agent
Sulfur containing silane series products include a variety of multifunctional silane coupling agents that have been successfully used in the rubber and plastic industry. Its application can improve the physical and mechanical properties of rubber, significantly improve the tensile strength, tear strength, wear resistance and other properties of rubber, reduce permanent deformation, reduce the viscosity of rubber and improve the processing performance. It is especially suitable for vulcanized rubber systems with silica or silicate as reinforcing agent. Its applicable fillers include silica, talc powder, clay, mica powder, clay, etc., and applicable polymers include NR, IR, SBR, Br, NBR, EPDM, etc.
Application case:
• applied to tires and cots: it can improve wear resistance, reduce hysteresis, enhance modulus, maximize bonding performance, improve processing performance, tread wear resistance, thermal cracking, bonding performance of carcass and filler, and bonding performance of tire buffer layer.
• apply to footwear: improve wear resistance, cutting resistance and pressure resistance, and improve flexibility.
• apply to roller: improve wear resistance, anti-aging performance, bearing capacity, improve processing performance, and reduce water absorption and hysteresis.
• applied to mechanical casting products: enhance modulus and thermal aging performance, improve dynamic performance, and reduce the expansibility to viscous solvents.
