IOTA-550 (KH-550) is a simple-structured, high-performance aminopropyltriethoxysilane (APTES), which is widely used in various bonding, surface treatment and polymer modification scenarios. Its molecules contain active primary amine groups and hydrolyzed triethoxysilane groups, which can form chemical bonds with the surfaces of organic resins and inorganic materials, respectively, thereby significantly improving the interfacial bonding strength.

As a general-purpose silane coupling agent, IOTA-550 has extremely wide applications, mainly including:
1.Silicone sealants and polyurethane adhesives: improve interfacial wettability and adhesion;
2.Inorganic filler (such as talc, calcium carbonate, wollastonite) treatment: improve compatibility and dispersibility with resins;
3.Glass and metal surface treatment agents: form a stable silane protective film to improve corrosion resistance;
4.Plastic modification (such as PA, EVA, etc.): improve polarity, hydrophilicity and inkability;
5.Packaging materials in the electronics and electrical industries: enhance moisture resistance and electrical insulation performance.

IOTA-550 is not only reliable in performance, but also has cost advantages and good compatibility with a variety of substrates. It is one of the most cost-effective coupling agents. In China and the global market, IOTA-550 ranks among the top in sales in the adhesive, composite materials, modified plastics, and glass fiber industries.

If you are looking for a silane additive with strong reactivity, wide adaptability, and reasonable price, IOTA-550 will be your ideal choice.
