IOTA ST4 High-Temperature Resistant Waterborne Nano Ceramic Coating, a premium high-gloss topcoat by IOTA Group, is engineered for extreme environments. As a water-based, pure solvent-free solution, it redefines surface protection for metals, glass, ceramics, and wood with three core strengths: 9H superhardness, 900℃ heat resistance, and all-round stain resistance. Blending eco-friendliness with ultimate performance, it delivers long-lasting defense for high-temperature and corrosive scenarios.

Unrivaled Performance, Breaking Limits

• 9H Diamond Hardness: Crafted with advanced nano-formulation, it achieves 9H pencil hardness after curing, offering exceptional scratch and abrasion resistance. Ideal for anti-graffiti metal surfaces and stain-proof glass facades, it maintains a high-gloss finish with minimal daily wear.
• 900℃ Heat & Fire Resistance: Surpassing conventional coatings, it withstands up to 900℃, forming a fire-retardant layer on wood to slow flame spread. Metals and ceramics stay protected in high-heat conditions without discoloration or cracking.
• All-Round Stain Resistance & Eco-Safety: Zero formaldehyde or benzene emissions ensure无毒 application, meeting strict environmental standards. The cured coating repels dust, oil, and chemicals, allowing easy cleaning and reducing maintenance costs by 80%.

Flexible Application, Versatile Use
Suitable for brushing, pouring, spin-coating, etc., with optimal performance at dry film thickness <10μm. Fast curing options: 10 minutes at 150℃ for initial hardness (5-8H), 3 hours for full 9H cure; or 30-minute touch-dry/7-day full cure at room temperature. Available in 25kg/200kg packaging, it stores safely for 6 months at 5-35℃ and ships as non-hazardous goods.

From high-temperature kitchen appliances and industrial anti-corrosion to architectural facade protection, IOTA ST4 combines "safety, performance, eco-friendliness" to build an indestructible shield for your surfaces!
