IOTA-OPSZ-9150 is a one-component transparent polysilazane resin featuring room-temperature curing, ultra-hardness (up to 9H), and excellent adhesion. It forms a 3D cross-linked film with >90% light transmittance, UV resistance, and organic solvent tolerance (alcohols, ketones), ideal for anti-graffiti coatings, metal corrosion protection, and resin modification.
Key Advantages
-
Room-Temperature Curing for Efficiency：Fully cures in 3 days at 20-25℃ (tack-free in 2h); accelerated curing (3h RT + 2h@120℃) achieves 8H hardness, suitable for large-scale industrial coating.
-
Ultra-Hard & Durable Protection：Hardness increases over time (4H→6H in 3 days) with 105° water contact angle for easy cleaning. 99% solid content ensures ＞1000h salt spray resistance, extending metal corrosion protection by 3x.
-
Universal Substrate Adhesion：Si-NH-Si bonds react with substrate -OH, achieving 0-level adhesion (cross-cut test) on metal, glass, and concrete without primers.
Technical Highlights
-
Low Viscosity for Versatile Application：50cPs fluidity enables spraying/ brushing/ dipping, with uniform film thickness (5-50μm);
-
Eco-Friendly & Safe：Non-flammable, VOC-compliant, suitable for indoor/outdoor use;
-
Multi-Functional Modification：Acts as curing agent or hardener, enhancing substrate hardness by 2-3H with 5%-10% addition.
Applications
-
Architectural Protection：Anti-graffiti wall coatings;
-
Industrial Anti-Corrosion：Bridges, pipelines, marine metal coatings;
-
Material Modification：Resin hardening, silicone rubber surface treatment;
-
High-End Decoration：Furniture, electronic casing transparent wear-resistant coatings.
IOTA-OPSZ-9150 redefines protective resins with room-temperature curing and robust performance, reducing costs and boosting durability for industrial innovation.
