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.
