It is a useful modifier for many high performance products including optical fibers, acrylics, epoxies, unsaturated polyester-fiberglass composites, and sol-gel composites. The reactive acrylic group can be copolymerized with many different unsaturated organic monomers such as vinyl monomers, organoacrylic monomers, styrene, or modified styrenes (copolymerization parameters e = 0.07, Q = 2.7). This yields polymers bearing pendant trimethoxysilyl groups, which can serve several different purposes. These groups can render a system cross-linkable upon exposure to water such as atmospheric moisture or steam. The pendant trimethoxysilyl groups can also improve the physical properties of composites by enabling the organic polymer to bond directly with the inorganic filler. Furthermore, these pendant trimethoxysilyl groups can dramatically improve the adhesion of organic polymers to many inorganic and metallic substrates. Vea Menos | |

The reactivity and compatibility of this polyfunctional alkoxysilane product makes it an ideal candidate to improve the properties of many different materials. For example, KBM-974 signif icantly improves the flexural and tensile strengths of glass fiber composites, especially in applications involving long-term exposure to water and high humidity. KBM-974 improves the chemical bonding between inorganic fillers and organic resins and the adhesion of composites and organic polymers to inorganic surfaces. Diluted solutions of KBM-974 are useful primers for bonding organic materials to inorganic surfaces. Similar to other silane coupling agents, formulations containing KBM-974 often demonstrate better processing characteristics. KBM-974 is an especially effective coupling agent and dispersing aid in thermoset composites such as epoxies, unsaturated polyesters, and polyimides, and works well in mineral-filled thermoplastics such as polypropylene, polybutyleneterephthalate, PVC, nylons, and polycarbonates. It is an ideal choice for many electronics applications because of its excellent head resistance to solder. Vea Menos | |
