IOTA ST4, a high-gloss topcoat, redefines surface coating standards with "zero-VOC环保+ ultimate protection". Its water-based formula eliminates formaldehyde, benzene, and toxic fumes, ensuring pollution-free application and safeguarding health and the environment—truly green coating.

Key strengths include: 9H pencil hardness for acid/alkali resistance, scratch resistance, and anti-graffiti performance; oil and stains wipe off effortlessly. Withstands 900℃ high temperatures, forming a fire-retardant barrier on wood, while providing long-term protection for metal, glass, and ceramics. The colorless transparent coating preserves substrate aesthetics, with adjustable wet film thickness (10-100μm) and optimal performance at dry film <10μm—balancing thinness and durability.

Application is versatile: suitable for brushing, pouring, spin coating, and rolling. Surface-dries in 30 minutes, fully cures in 7 days at room temperature; for rapid use, 150℃ baking achieves initial cure (5-8H hardness) in 10 minutes and full 9H hardness in 3 hours. Packaged in 25kg plastic drums or 200kg iron drums, it stores safely at 5-35℃ for 6 months and ships as non-hazardous goods.

From high-end furniture’s scratch-resistant finish to kitchen appliances’ heat-proof coating, and metal corrosion protection, IOTA ST4 delivers "eco-safety, ultra-high hardness, extreme heat resistance"—empowering your products with lasting gloss and all-round defense.
