Application
SilQon MTMO serves as a silane coupling agent and surface modifier in various industrial applications.
In adhesives and sealants, it promotes adhesion, particularly on substrates like glass, metals, and ceramics. In coatings and paints, it enhances adhesion to surfaces such as metals, plastics, and glass, improving durability and resistance. During rubber compounding, it boosts bonding between rubber and reinforcing fillers like silica or carbon black. In the production of fiberglass and composite materials, it acts as a coupling agent, improving mechanical properties by linking the resin and reinforcing fibers.
Furthermore, it modifies surfaces of metals, glass, and ceramics to enhance compatibility with other materials or coatings. For waterproofing and corrosion protection, its ability to bond with surfaces and repel water makes it effective as a corrosion inhibitor on metal surfaces. In electronic components, it improves adhesion between different layers or substrates, leading to better performance and reliability.
Overall, its versatile properties make SilQon MTMO a valuable component in many industrial processes that require enhanced adhesion, durability, and surface modification.
