As sealing and protective materials are pushed to perform in increasingly harsh environments, IOTA hydroxyphenyl silicone rubber is emerging as a key material for high-temperature sealing and advanced coatings, thanks to its outstanding thermal stability, weather resistance, and adhesion capabilities.

This material integrates both phenyl and hydroxyl functional groups into the siloxane backbone, greatly enhancing heat resistance and oxidation stability. The hydroxyl groups significantly improve adhesion to inorganic substrates like glass, ceramics, and metals, allowing it to maintain elasticity and structural integrity under prolonged exposure to 200°C–300°C.

In aerospace, power generation, and industrial furnace applications, IOTA hydroxyphenyl silicone rubber is used in the form of sealants, gaskets, and strips, providing long-term sealing performance where conventional organics fail due to aging or cracking.

It also plays an important role in high-performance coating systems. As a base or additive in silicone-modified weatherproof coatings, it enhances UV resistance and humidity endurance, extending the service life of building exteriors, electrical housings, and transportation infrastructure.

With the increasing demand for materials that withstand extreme temperatures and environmental stress, IOTA hydroxyphenyl silicone rubber is set to become a cornerstone in the next generation of high-performance materials and protective technologies.
