In modern building sealants and industrial adhesive systems, improving the adhesion of sealants to various substrates while maintaining system stability is a key focus of technological advancement. IOTA-902 (3-aminopropylmethyldiethoxysilane), a reactive silane coupling agent, is offering a novel solution to the industry with its unique chemical structure.

In polysulfide, silicone, and polyurethane sealants, IOTA-902 can serve as an adhesion promoter in both one- and two-component systems, and also assists in crosslinking during the curing process. Its amino-reactive groups react with the resin to form covalent bonds, significantly improving adhesion to substrates such as glass, copper, and concrete. Furthermore, the silane-oxygen bond network formed by the hydrolysis of the ethoxy groups reduces air bubbles within the system and improves cure uniformity.

Sealants using IOTA-902 offer exceptional performance: light color, bubble-free performance, and strong weather resistance. They are particularly suitable for applications in building curtain walls, electronic sealing, and precision assembly. As demand for high-performance sealing materials grows, the market for IOTA-902 will continue to expand.
