Polyester-modified silicone resin is a hybrid material synthesized via chemical modification, combining the extreme temperature resistance (-50℃~550℃) of silicone with the strong adhesion of polyester. After curing, its hardness exceeds 3H, with added hydrophobicity, moisture resistance, and anti-yellowing properties. Widely used in high-temperature coatings, outdoor decor, and electronics protection, it withstands over 250℃ in industrial equipment without cracking while maintaining superior gloss and color retention, making it ideal for premium coatings.
