Application of Phenylhydrosiloxane Resin in High-Temperature Resistant Coatings
The introduction of phenyl groups significantly enhances the high-temperature resistance of silicone resins (capable of withstanding 200-300°C for long-term use and over 500°C for short-term exposure). Meanwhile, the cross-linking reaction of Si-H bonds enables the coating to form a dense structure, improving adhesion and solvent resistance. Therefore, phenylhydrosiloxane resin is often used as a film-forming base material for high-temperature resistant coatings, with applications including:

• High-temperature components such as automobile exhaust pipes and engine cylinders, protecting the substrate from high-temperature oxidation and corrosion;
• Industrial equipment like boilers, chimneys, and high-temperature pipelines, extending their service life;
• Engine components and spacecraft surfaces in the aerospace field, withstanding extreme high-temperature environments.
