In industrial coatings, balancing "room-temperature fast curing," "high hardness protection," and "long-term weather resistance" is a challenge—until IOTA-OPSZ-9150. This transparent, one-component polysilazane resin redefines protective coatings with its unique Si-NH-Si bond structure, excelling in anti-graffiti, metal anti-corrosion, and resin hardening applications.

Key Advantages: Room-Temp Curing + 9H Hardness
IOTA-OPSZ-9150 eliminates the need for high-temperature baking: it fully cures in 3 days at 20-25°C (touch-dry in 2 hours) or reaches 8H hardness in 2 hours at 120°C for accelerated production. Post-curing, its 3D cross-linked structure delivers up to 9H hardness and a 105° water contact angle, ensuring superior scratch resistance and hydrophobicity. The coating resists alcohols, ketones, and organic solvents, with anti-UV and anti-oxidation properties, and is non-flammable, providing long-term protection against harsh environments and chemical erosion.

Versatile Applications

• Anti-Graffiti for Buildings: Transparent film preserves substrate appearance while enabling easy graffiti removal;
• Metal Anti-Corrosion: 0-class adhesion (cross-cut test) ensures tight bonding, preventing rust and extending equipment life;
• Resin Modification: Acts as a curing agent or hardener for silicone/organic resins, enhancing mechanical strength and weatherability;
• High Transparency: >90% visible light transmittance suits optical components and clear substrates, combining functionality with aesthetics.

Technical Highlights: Easy Application & Safety
With a low viscosity of 50cPs and solubility in ethers/alkanes, this colorless liquid enables smooth, uniform coating. Over 99% solid content minimizes volatility, while non-corrosive, low-migration properties ensure safety and stability. Whether for large-scale building spraying or precision part coating, IOTA-OPSZ-9150 guarantees consistent, reliable protection.

Choose IOTA-OPSZ-9150—where room-temperature efficiency meets 9H hardness, empowering durable, transparent protection for diverse industrial needs.
