In surface protection fields such as automotive glass, rearview mirrors, metal components, and ceramic ware, the four-dimensional indicators of "transparency — super-hydrophobicity — application convenience — long-acting protection" of functional coatings have always been the core contradiction restricting end-product texture and user experience. Traditional surface protection solutions either rely on heavy anti-rust paints and plating layers that obscure the original gloss and light transmittance of substrates, destroying aesthetic appearance; or adopt fluorine-containing solvent-based systems with high environmental pressure and narrow application windows. Some ordinary hydrophobic agents, while providing short-term water repellency, have large rolling angles and water drag marks. During rainy driving, they still form continuous water films on glass surfaces, affecting visibility safety, and their abrasion resistance and adhesion are insufficient, easily failing due to daily wiping. With the continuous upgrading of comprehensive demands in automotive, architectural curtain walls, and home hardware for "transparent and colorless, water non-stick, green environmental protection, convenient application", finding a super-hydrophobic nano coating "based on nano hydrophobic materials, rolling angle less than 10°, forming a transparent nano coating on glass/metal/ceramic surfaces, with a shelf life of up to 3 years" has become the core proposition for the refinement of domestic functional nano coatings. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. officially launches IOTA ST5 Transparent Super-Hydrophobic Nano Coating. With "hydrophobic nano factor, surfactant, deionized water" as main ingredients; "colorless to transparent liquid; solid content 5%; adhesion grade 0; wet film thickness 100-500μm; dry film thickness 50-200μm" as core parameters; backed by "micro-nano construction of hydrophobic nano factor + super-hydrophobic water-slip + transparent long-acting", it serves as the "transparent shield choice" for surface protection, achieving the leap from "traditional heavy opaque protection coatings" to "transparent super-hydrophobic nano water-slip protection". System Positioning: Super-Hydrophobic Nano Coating vs. Traditional Surface Protection Coatings IOTA ST5 belongs to a functional coating system developed based on nano hydrophobic materials, distinct from traditional anti-rust paints and fluorine-containing platings. Traditional protective coatings are mostly formed by accumulation of film-forming substances, with thick films that cover substrates, and hydrophobic angle usually less than 110°, leaving water drag marks. IOTA ST5 innovatively combines hydrophobic nano factor with surfactant and deionized water — the hydrophobic nano factor builds a micro-nano rough structure on glass, metal, ceramic and other surfaces, while the surfactant regulates spreading wettability. After film formation, an invisible transparent nano coating is formed, thoroughly solving the industry pain points of "protective coatings being opaque, insufficient hydrophobicity, and cumbersome application". Molecular Architecture: Hydrophobic Nano Factor + Surfactant + Micro-Nano Transparent Film The core competitiveness of IOTA ST5 stems from the precision formulation design of super-hydrophobic nano coating:

• Hydrophobic Nano Factor: As the core film-forming component, it builds a micro-nano rough structure on the substrate surface, giving the coating extremely low surface energy, making the water droplet rolling angle less than 10°, water non-stick, achieving true super-hydrophobic effect.
• Surfactant: Regulates the spreading wettability of the coating on heterogeneous surfaces such as glass, metal, and ceramics, ensuring uniform film formation and adhesion reaching grade 0, with a firm bond between coating and substrate.
• Micro-Nano Transparent Film: A 5% solid content coating with a dry film thickness of 50-200μm forms an extremely thin transparent and colorless film, which does not block the original gloss and light transmittance of the substrate, with high transparency in the visible region, suitable for scenes with strict appearance requirements.

Performance Leap: From "Heavy Opaque" to "Transparent Super-Hydrophobic Water-Slip" Introducing IOTA ST5 brings a qualitative leap to surface protection:

• Super-Hydrophobic Water-Slip: Rolling angle less than 10°, water droplets roll off rapidly on the coating surface, unable to form a continuous water film, carrying away surface dust for self-cleaning.
• Completely Transparent: Colorless to transparent liquid, the formed film is invisible to the naked eye, fully preserving the original gloss and texture of automotive glass, rearview mirrors, metal, and ceramics.
• Excellent Adhesion: Adhesion grade 0, the coating bonds firmly with the substrate, resistant to friction and wiping, long-acting and durable.
• Convenient Application: After spraying, wipe evenly with a lint-free cloth; instant curing by baking at 160°C for 3 minutes; or bake at 50-100°C for 10-30 minutes, with low energy consumption and a wide process window.
• Green Environmental Protection: Using water as the dispersion medium, with hydrophobic nano factor, surfactant, and deionized water as main ingredients, it is convenient to use and environmentally friendly.
• Long-Acting Protection: 3-year shelf life; if the coating is damaged by friction and loses super-hydrophobic effect, it can be restored by re-treatment.

Application Penetration: From Automotive Glass to Home Ceramics The application boundary of IOTA ST5 covers all hard-surface scenarios requiring "transparent super-hydrophobic + easy-clean protection":

• Automotive Rearview Mirrors and Glass (Main Battlefield): Forms a super-hydrophobic water-slip layer on rainy days. When driving at speed, water droplets are rapidly blown away by airflow, reducing wiper frequency and improving driving visibility safety.
• Metal Surfaces: Forms a 50-200μm transparent hydrophobic film on metal components, blocking contact between moisture, oxygen and metal, delaying oxidative rust from the source, while maintaining the original metallic luster.
• Ceramic Surfaces: Used on ceramic ware, tiles, and sanitary ceramics, water droplets roll off rapidly without staining, easy to clean and resist dirt, reducing cleaning frequency.
• Other Hard Surfaces: Suitable for surface protection of precision instrument lenses and display cabinet glass where light transmittance is required.

IOTA Technical Guide: Clean Dry, Spray and Bake

• Application: Thoroughly clean glass, metal and other surfaces before use, wipe or dry them; spray the coating on the surface, wipe evenly with a lint-free cloth or toilet paper, wait a few seconds, then wipe the surface clean and translucent; cure by baking at 160°C for 3 minutes, or at 50-100°C for 10-30 minutes.
• ⚠️ Taboo: Devices after super-hydrophobic treatment should not be rubbed with sandpaper to avoid contamination with oil; strictly prohibited to swallow, if accidentally gets into eyes, rinse immediately with water for 15 minutes; keep away from children; keep away from high temperature, fire sources, avoid direct sunlight, do not puncture or burn the container.
• Storage: 3-year shelf life; store as general chemicals, avoid high temperature and direct sunlight.
• Handling: Colorless to transparent liquid, 5% solid content for easy metering; packaging 200kg or 1000kg plastic or iron drums; wet film 100-500μm, dry film 50-200μm, controllable coating thickness.

Industry Insight: In the field of functional nano coatings, the formulation design of IOTA ST5 — "micro-nano construction of hydrophobic nano factor + surfactant wetting and spreading + extremely thin transparent film" — is the key path to achieving the trinity of "super-hydrophobic + transparent + long-acting" — the introduction of hydrophobic nano factor solves the industry pain point of traditional protective coatings: "heavy opaque, insufficient hydrophobicity", while the 5% solid content extremely thin film formation ends the application shortcoming of ordinary hydrophobic agents: "thick film covering substrate, affecting appearance". IOTA ST5, with "rolling angle <10° + adhesion grade 0 + 5% solid content + 3-year shelf life" hard metrics, fills the key supply chain link for domestic transparent super-hydrophobic nano coatings in automotive glass, rearview mirrors, metal and ceramic protection, providing a mass-producible transparent long-acting high-performance super-hydrophobic nano coating for downstream automotive aftermarket, hardware processing, and architectural sanitary ware enterprises. This confirms that domestic functional nano coatings are leaping toward "heavy anti-rust paint → fluorine-containing plating → transparent super-hydrophobic nano coating" in terms of transparency and hydrophobicity, with growing technical say in high-end surface protection fields.
