In the fields of construction, transportation, electronics, and packaging, surface contamination, corrosion, and barrier failure remain core pain points affecting product lifespan and performance. Traditional organic coatings age easily and lack wear resistance, while pure inorganic coatings suffer from complex application and poor adhesion. Today, we present a revolutionary solution rooted in pure inorganic chemistry: Perhydropolysilazane Liquid Coating Material IOTA PHPS (Hydrophilic Super Hard Stain Resistant Nano-Coating Materials) . It integrates the exceptional performance of inorganic silica with the convenience of liquid application, offering super-hydrophilicity, outstanding stain resistance, high hardness, and strong adhesion for your substrates.

Inorganic Essence, Low-Temperature Ceramic Formation

At the core of IOTA PHPS is Perhydropolysilazane (PHPS) , a unique inorganic polymer. Supplied as a colorless transparent liquid with 20% solid content in n-butyl ether, it is extremely easy to apply. Under relatively mild conditions, PHPS undergoes hydrolysis and polycondensation, in-situ converting into a pure, dense, inorganic silicon dioxide (SiO₂) nano-coating. This conversion requires no high-temperature sintering, making it suitable for heat-sensitive substrates like glass, metals, plastics, and semiconductor materials.

Super-Hydrophilic Self-Cleaning, Effortless Renewal

The converted SiO₂ coating possesses intrinsic super-hydrophilicity. Water spreads completely into a uniform film, easily penetrating and lifting dust, oil, graffiti, and other contaminants, which are then carried away by the flow. This achieves genuine “rain self-cleaning, clear-water rinsing.” This feature is particularly outstanding in anti-graffiti building facades, rail vehicle exteriors, and precious metal anti-corrosion—stains hardly adhere, drastically reducing cleaning and maintenance costs.

High Hardness, Scratch Resistance, Long-Term Protection

The cured coating has a density of 1.6-2.0 g/cm³, forming a dense, high-hardness structure that resists abrasion and scratching. It also offers excellent oxidation and corrosion resistance, providing long-term, stable protection for substrates. In precision fields such as semiconductor insulation layers, electronic circuit protection, and plastic packaging gas/water barrier, PHPS’s pure inorganic nature eliminates the aging and outgassing issues of organic materials, enhancing device reliability and packaging shelf life.

Application-Friendly, Broad Compatibility

With 20% solid content and suitable viscosity, the product can be applied by spraying, dipping, or brushing, and exhibits excellent adhesion to metals, glass, ceramics, and polymers. Room-temperature curing offers a wide process window and flexible production.

From self-cleaning architectural facades, anti-graffiti high-speed trains, and anti-fingerprint coatings for jewelry, to chip passivation layers, flexible electronic barrier films, and high-barrier food packaging coatings—IOTA PHPS endows surfaces with the dual gifts of “self-cleaning” and “super protection” through inorganic purity and intelligence. Choosing it means harnessing the primal power of chemistry to make cleanliness and durability a permanent norm.
