Usage: 1 ) Surface treatment, including particle treatment, such as pigments and fillers, or formulated into primers and water repellents; 2 ) Added to paints, inks and adhesives; 3 ) Silicone resin synthesis or organic resin modification Sexual reactive intermediates. Special considerations are required when using any of the above methods. For pigment and filler treatments, typical concentrations are 0.5 to 1.0 %. The most straightforward way to silylate a surface is with an alcoholic solution. A 2 % solution of silane can be prepared in the alcohol of choice (typical choices are methanol, ethanol or isopropanol) . Solutions can be applied to surfaces by rubbing, dipping or spraying. When dipping larger objects such as glass dishes, the immersion should be continued for 1 to 2 minutes to allow the silane to migrate to the surface. After the surface is dry, gently wipe off the excess material, or rinse it off with rubbing alcohol. Add particles such as pigments and fillers into the solution and stir for 2 to 3 minutes to realize the silylation reaction, and then precipitate out of the solution, then rinse the particles with alcohol, and finally in 110 °CThe reaction was heated at room temperature for 5 to 10 minutes, or at room temperature for 24 hours to complete the reaction. As a primer, an aqueous solution of silane in alcohol improves flow and adhesion. The pH of the solution containing 95 % ethanol and 5 % water was adjusted to 3.5 to 4.0 with acetic acid and the silane was added with stirring to a final concentration of 0.5 to 2.0 %. In general, wait 6 hours for complete hydrolysis, silanol formation, and equilibration. Low VOC aqueous solutions can be prepared by dissolving 0.5 to 2.0 % silane in pH -adjusted water ( adjust pH to 3.5 to 4.0 with acetic or formic acid). Filler and pigment treatments are usually done by spraying. It is assumed that the total amount of silane required is known and that there are sufficient hydroxyl groups on the filler to react with the silane. The powder is placed in a high-intensity solids mixer, such as a double-cone mixer with an intensifier. Pump Silane X into the blended powder as a fine spray. The dynamic drying method is the most effective.
additive Silanes or mixtures with other silanes are also available as additives ( 0.1 to 3.0 % solids by weight). The silane becomes an integral part of the coating and is thus dispersed or migrated to the substrate where it reacts. Its advantages include improving pigment dispersibility, reducing pigment floating, improving adhesion and film hardness, etc. reactive intermediate Due to their highly reactive methoxyl groups, organic compatibility, and unique silicone chemistry, silanes offer coating formulators a variety of straightforward synthesis solutions for high-performance applications. Silane mixtures are hydrolyzed in slightly acidic solutions, and silicon – organic mixtures or 100 % novel silicone resin polymers can be easily synthesized . A low VOC material can be produced by balancing the linear component, the degree of hydrolysis, and the methanol produced during hydrolysis. These materials are used in paints, primers, inks and adhesives where good adhesion, weatherability and high temperature stability are required. |
