introduction | silane coupling agent A- 172 is a vinyl silane, its molecular structure has a vinyl functional group containing an unsaturated double bond structure and three hydrolyzable alkoxy-2-methoxyethoxy, this dual reactivity allows them to improve the degree of bonding, adhesion and compatibility between the inorganic materials (glass, metal, filler) and organic polymers (thermosetting resin, plastic, elastomer) through the two-way chemical reaction, thereby improving the mechanical properties of the resin-based composite material or improving the adhesive strength and water resistance of the resin coating. In different applications, they can be used as coupling agents, adhesion promoters, cross-linking agents, surface modifiers for pigments and fillers, silicone modified graft comonomers, etc. |
use | A-172 is a bifunctional molecule, which can react with inorganic fillers or organic polymers. It can be used as an adhesion promoter for a variety of minerals: aluminum hydroxide, magnesium hydroxide, kaolin, silica and other filled polymers, which can improve its mechanical and electrical properties, especially after exposure to moisture, the effect is better. Once this product is combined with inorganic fillers, the surface of the filler will be hydrophobized. This effect can improve the compatibility of the filler and the polymer, so that the dispersion is better, the melt viscosity is reduced, and the processing of the filled plastic is easier. Used as a cross-linking agent for polymer material modifiers, ethylene propylene ternary rubber modifiers, and silane cross-linked cable materials Used as a glass fiber treatment agent and also used in the manufacture of water repellent |
