In construction, transportation, electronics, and packaging, surface contamination, corrosion, and barrier failure are silent killers of product lifespan and performance. Traditional organic coatings age easily and lack wear resistance, while pure inorganic coatings suffer from complex application and poor adhesion. IOTA PHPS Perhydropolysilazane Liquid Coating Material shatters this deadlock.
IOTA PHPS is based on perhydropolysilazane, diluted in n-butyl ether. It is a colorless transparent liquid with 20% solid content. Density: 0.82-0.84 g/ml (20% solution), 1.16-1.31 g/ml (100% liquid). Viscosity is suitable for spraying, dipping, or brushing. It cures under mild conditions: 7+ days at room temperature, or 2 hours at 150°C with 90% humidity. Through Si-N bond hydrolysis and polycondensation, it converts in-situ into a pure, dense SiOx nano-coating with cured density up to 1.6-2.0 g/cm³, forming a true glass-like protective layer.
Performance data is convincing: coating thickness >100 nm, pencil hardness up to 9H (China) or 6H (Mitsubishi). High-temperature curing yields hardness of 8-10 GPa and elastic modulus of 100-130 GPa; ammonia curing achieves 3 GPa/60 GPa. Visible light transmittance >90%, cross-cut adhesion Class 0. It withstands 800°C in air, with strong rust, alkali, and brine resistance, and about one month resistance to 10% HCl. In semiconductor insulation layers, electronic circuit protection, and plastic packaging gas/water barrier, its pure inorganic nature eliminates aging and outgassing issues of organic materials, significantly improving device reliability and packaging shelf life.
Applications are broad: anti-graffiti buildings, precious metal anti-corrosion, rail transit, semiconductor insulation, electronic circuits, and plastic packaging barrier. From self-cleaning architectural facades to chip passivation layers, IOTA PHPS endows surfaces with dual gifts of self-cleaning and super protection through inorganic purity and active hydrophilicity. Choose it to make cleanliness and durability a permanent norm.
