The newly launched resin combines excellent stain resistance, weatherability, and long-term gloss retention with simple, eco-friendly application. Designed as a single-component, moisture-curing system, SIO-521 forms a transparent protective film that delivers anti-graffiti Level 1 performance and exceptional surface durability.According to the company, the coating exhibits a water contact angle of approximately 110° and an oil contact angle of around 30°, allowing contaminants such as ink, paint, or grease to be easily wiped away. Its film reaches 9H pencil hardness with an adhesion rating of 0, offering outstanding wear resistance and mechanical strength.Unlike many conventional polymer coatings, SIO-521 maintains high clarity and gloss even after prolonged UV exposure or chemical contact. The resin withstands boiling water, 300°C heat, and exposure to solvents such as alcohol, PMA, and thinner, while remaining resistant to acids, alkalis, and everyday stains like vinegar, red wine, and cola.The coating is suitable for use on metal, stone, wood, GRC, plastics, advertising panels, and powder-coated surfaces. It provides waterproofing, oil repellency, and easy-to-clean properties, restoring aged or damaged coatings and improving surface appearance. The formulation's low odor, nonflammable nature, and moderate curing speed also make it practical for field and workshop applications.
