IOTA PHPS perhydropolysilazane (inorganic polysilazane) stands out with excellent solubility, short curing time, and multi-substrate adhesion, serving as a high-performance coating material for anti-graffiti buildings, precious metal anti-corrosion, rail transit, and more. Its core advantage lies in converting to dense SiO₂ film at low temperatures (150℃), combining inorganic materials' high-temperature oxidation resistance with organic coatings' construction convenience, redefining surface protection material standards.

Core Performance & Technical Breakthroughs

• Diverse curing methods：Supports moisture curing (90% humidity/150℃/2h), high-temperature curing (200-300℃ accelerated conversion), and room-temperature curing (25℃/7 days), adapting to various substrates and processes.
• Superior multi-substrate adhesion：0-class adhesion (cross-cut test) on metals (aluminum alloy, stainless steel), ceramics, and polymers (PP, PC, PVC), solving traditional coatings' poor adhesion on difficult substrates.
• Comprehensive functional properties：Coating hardness up to 3GPa (ammonia curing), elastic modulus 60GPa, transmittance >90%, with temperature resistance (stable at 800℃ in air), oxidation resistance, and corrosion resistance (＞90% performance retention after 1-month 10% hydrochloric acid immersion).

Application Field Solutions

• Building anti-graffiti：Transparent coating provides low surface tension (water contact angle >105°), enabling easy graffiti removal with over 5-year protection per application.
• Precious metal anti-corrosion：Nano-scale SiO₂ film isolates air and moisture, preventing oxidation discoloration of silver, copper, etc., maintaining long-term luster.
• Rail transit & electronic circuits：High-temperature oxidation resistance protects metal parts from high-temperature oxidation; dielectric strength >40kV/mm and volume resistivity >10¹⁴Ω·cm for semiconductor insulation layers.
• Plastic packaging gas/water barrier：Coated on PET film, reduces oxygen transmission rate by 90% and water vapor transmission rate by 85%, extending food shelf life.

Construction & Storage Advantages

• Flexible construction：Applicable via spin coating, spraying, dipping; solid content adjustable (2-20%), precise film thickness control (0.5-5μm).
• Stable storage：1-year shelf life unopened; >6-month pot life after opening when sealed and stored at low temperature (0-5℃).
