In the high-end decorative and protective topcoat spectrum, conventional two-component PU/acrylic topcoats are plagued by "slow RT cure (>7 days), limited hardness (≤3H), heat resistance <200℃, weak hydrophobicity, prone to yellowing"; while high-temp sintered ceramic glaze requires >300℃ baking, incompatible with heat-sensitive substrates like wood and plastics. IOTA ST3, built on a "nano-oxide one-part conversion coating" architecture, air-dries to tack-free in 10 minutes and fully cures in 3 days; with 150℃/2min thermal cure, it forms a 5-8H pencil-hard (GB/T 6739-1996), 0-grade adhesive (GB/T 9286-1998), 1-5μm dry film, 400℃-resistant, highly hydrophobic transparent high-gloss glaze. As metal workpieces, glassware, ceramic sanitary ware, and wooden furniture surge in demand for "ambient fast-dry + high-hardness scratch resistance + high-gloss decoration + thermal durability" bundles, sourcing a "50% solids, one-part, RT-cure/heat-cure dual-mode, 5-8H, 0-grade, 400℃, non-haz, domestically mass-producible" nano ceramic topcoat has become the core proposition for multi-substrate "crystal-coating-grade" decorative protection upgrade.
Addressing this "quick-glaze" pain point,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches
Self-Drying Super Hard Nano Ceramic Coating IOTA ST3. Characterized by "colorless transparent liquid, weight solids 50%, wet film 10-20μm / dry film 1-5μm, pencil hardness 5-8H (GB/T 6739-1996), 0-grade adhesion (GB/T 9286-1998), transparent high-gloss coating, 10min tack-free / 3 days full cure, 150℃/2min thermal cure, 400℃ resistance, 5-35℃ sealed storage, 25kg PE/200kg iron drum, non-haz, 24-month shelf", and backed by "nano-oxide one-part + conversion-type film formation + RT/heat dual-mode cure + high-gloss glaze," it serves as the "quick-glaze topcoat" for metal, glass, ceramic, and wood furniture finishes and crystal coatings.
Molecular Architecture: Nano-Oxide One-Part + Conversion-Type Film + Dual-Mode Cure 3D Logic
The core competitiveness of IOTA ST3 stems from its "nano-oxide precursor + one-part air-dry conversion + RT-cure/heat-cure dual-mode trigger" precise composite architecture:
-
Nano-Oxide Precursor: The coating's main component is nano-oxide in a 50% solids colorless transparent liquid system; after application, nanoparticles densely pack on the substrate surface, forming a dense inorganic-organic hybrid network — the fundamental source of 5-8H hardness and high transparency/gloss.
-
One-Part Conversion-Type Film: Unlike conventional 2K PU/epoxy requiring metering and mixing, ST3 is truly one-part — ready to use out of the can, air-dries and converts without external crosslinker; nanoparticles build a 3D network via physical/chemical interactions.
-
Dual-Mode Cure Flexibility: Ambient air-dry 10min tack-free, 3 days full cure; if production line allows, 150℃/2min thermal cure achieves optimal properties — perfectly balancing field application (air-dry) and factory tempo (heat cure).
Performance Leap: From "2K Slow-Dry Soft Lacquer" to "One-Part Quick-Glaze Hard Topcoat"
Incorporating IOTA ST3 enables qualitative leaps:
-
5-8H Ultra-Hard Scratch Resistance: Far exceeds conventional decorative topcoats' 2-3H, effectively resisting daily wear, scrubbing, minor impacts.
-
10-Min Ultra-Fast Tack-Free: Air-dry 10min tack-free, 3 days full cure; 150℃/2min thermal cure achieves optimal performance — application efficiency improved several-fold vs. 2K coatings.
-
0-Grade Adhesion: Top cross-cut rating (GB/T 9286-1998), seamless bonding to metal, glass, ceramic, wood; no peeling under long-term use.
-
400℃ High-Temp Resistance: Withstands 400℃ service conditions, suitable for kitchen appliances, heating equipment, exhaust pipe fittings and other high-temp scenarios.
-
High-Gloss Transparent + Hydrophobic: Post-cure colorless transparent high-gloss glaze; excellent hydrophobicity makes stains and scale wipe clean easily, smooth and delicate touch.
-
Eco-Friendly One-Part: Water-based system, no formaldehyde/benzene emissions during application; one-part ready-to-use, no metering; yellowing-resistant, long-term high gloss.
-
Vs IOTA ST6/PHPS: ST6 is silicone resin nano-ceramic (5H, 500℃, multi-substrate universal protection); PHPS is perhydro inorganic polysilazane (9H, 800℃, inorganic ceramic precursor for anti-graffiti/semiconductor); ST3 is nano-oxide one-part conversion-type (5-8H, 400℃, focused on high-gloss topcoat and crystal coating decoration) — together they form a "ST6 ceramic armor protection / PHPS ceramic seed inorganic / ST3 quick-glaze high-gloss topcoat" coating functional triangle.
Application Penetration: From Metal Workpieces to Wood Crystal Coating
IOTA ST3 covers topcoat and crystal-coating scenarios sensitive to "fast-dry, high-hardness, high-gloss, heat resistance, hydrophobicity":
-
Metal Topcoat: Hardware, appliance panels, aluminum profiles, stainless steel decorative parts — high-gloss glaze, scratch and corrosion resistant.
-
Glass Crystal Coating: Glassware, shower enclosures, vehicle windows — hydrophobic and easy-clean, water beads roll off quickly.
-
Ceramic Sanitary Ware: Tiles, sanitary fixtures, bathroom accessories — high-gloss decoration + anti-stain easy-clean.
-
Wood Furniture Topcoat: Premium furniture, flooring, wood doors — ambient air-dry without damaging wood, high-gloss grain enhancement.
-
Crystal Coating Decoration: Handicrafts, ornaments, collectibles surface crystal coating protection, enhancing gloss and durability.
IOTA Technical Guide: Sand & Degrease, Thin Coat <10μm, Air-Dry or 150℃/2min
-
Substrate Prep: First polish the substrate and remove grease; clean thoroughly, ensuring surface is smooth and dry.
-
Application: Apply nano coating by spraying or brushing; when diluting, ethanol can be used; if leveling is poor, add appropriate leveling agent.
-
Film Thickness: Dry film thickness <10 microns for optimal performance — avoid thick coating.
-
Pick-One-of-Two Cure:
-
① Air-dry: Ambient 10min tack-free, 3 days full cure (ideal for field application and heat-sensitive substrates);
-
② Thermal cure: 150℃ bake for 2 minutes (ideal for factory lines, achieves optimal properties).
-
Storage: 25kg PE or 200kg iron drum; store sealed in cool dry 5-35℃, transported as non-haz, 24-month shelf life; routine PPE, ventilated application environment.
Industry Expert Insight:
Industry experts note that under the superimposed demands of metal decoration, glass-ceramic, and wood furniture for "ready-to-use + ambient fast-dry + high-hardness high-gloss + thermal durability," one-part nano ceramic topcoats are upgrading from "imported 2K system dominance" to "50% solids, 5-8H, 0-grade adhesion, RT-cure/heat-cure dual-mode, 400℃ resistance, 24-month shelf, domestic mass production" reference products. IOTA ST3, with "nano-oxide one-part + conversion-type film formation + quick-glaze high-gloss" hard metrics,
fills the domestic supply chain gap for one-part air-dry nano ceramic topcoats in metal/glass/ceramic/wood multi-substrate fields, providing a mass-producible import-substitution solution for downstream hardware, appliance, sanitary ware, and furniture enterprises. This confirms domestic functional topcoats are advancing steadily along "2K PU/acrylic (slow-dry soft lacquer) → nano ceramic one-part (quick-glaze hard topcoat)", with growing technical say in multi-substrate decorative protection critical materials.
