SIOResin launches solvent-free resin for automotive ceramic coatings

SIOResin has introduced SIO-9233, a solvent-free methyl polysilazane resin for automotive exterior and interior protective coatings. The company says the material is built to deliver hardness, hydrophobicity, anti-graffiti performance and high-temperature resistance for formulators seeking room-temperature curing systems.

Why it matters: - Automotive coatings need to do more than add shine. They also have to resist scratches, chemicals, water, stains and heat. - SIOResin is positioning SIO-9233 as a multifunctional resin for coating makers building ceramic protection systems for cars and other hard surfaces. - The product is meant to support ambient-temperature processing, which can simplify production compared with high-temperature bake systems.

What happened: - SIOResin introduced SIO-9233, a solvent-free methyl polysilazane resin for high-performance organic polysilazane ceramic coatings. - The resin is designed for automotive exterior and interior surface protection. - The launch was announced Oct. 6, 2026 in New York. - More information is available in the company's product page and the related OPSZ explainer.

The details: - The cured coating can reach up to 9H pencil hardness. - Internal testing showed a water contact angle of about 110°. - Internal testing also showed oil-based permanent marker could be removed by dry wiping from the cured coating. - The resin is designed to provide scratch resistance, abrasion resistance, chemical resistance, hydrophobicity and easy cleaning. - SIO-9233 is also designed for high-temperature resistance up to 800°C under relevant test conditions. - Surface drying can be achieved in about 30 to 60 minutes under suitable curing conditions. - The resin is intended for automotive paint, clear coats, metal components, plastics, trim and other hard surfaces. - SIOResin says SIO-9233 is available in 1KG, 5KG and 25KG packaging. - The company says the shelf life is 12 months when stored under appropriate conditions.

Between the lines: - The launch reflects growing demand for coatings that protect appearance while handling real-world wear and exposure. - The combination of hardness, water repellency, stain resistance and room-temperature curing is aimed at formulators trying to balance performance with processing flexibility. - Performance values are based on internal laboratory testing and can vary with formulation, substrate, coating thickness and curing conditions.

What's next: - Coating formulators will need to test the resin in full systems before commercial use. - SIOResin is directing interested customers to its website and sales channel for samples and technical support. - The company is also promoting the resin as a platform for next-generation automotive ceramic coatings and paint protection systems.

The bottom line: - SIO-9233 gives automotive coating developers a solvent-free polysilazane option built around hardness, easy cleaning and moisture curing.
