In the fields of aerospace, industrial heavy-duty anti-corrosion, and specialty composites, the limits of surface protection are constantly being redefined. While traditional high-temperature coatings often compromise between application convenience, substrate versatility, and thermal resistance, a truly professional-grade material designed for "all-scenario high-temperature performance" is now ready. We proudly present Organopolysilazane IOTA 9118 (Ceramizable Precursor Polymer). This is a liquid polysilazane featuring vinyl as the primary functional group, precisely tailored for high-performance, high-temperature resistant coating systems, delivering exceptional comprehensive performance backed by detailed data.

Data-Proven Excellence
IOTA 9118 is a pale yellow transparent liquid with an ultra-low viscosity of 10-40cp, ensuring exceptional leveling and penetration for spraying, brushing, dipping, or spreading. With purity >99%, molecular weight of 1200-1400, and density of 0.98-0.99 g/cm³, quality is consistently reliable. The cured coating achieves pencil hardness of 6-7H, water contact angle of 100-105°, combining robust hardness with self-cleaning properties; visible light transmittance >95% preserves substrate aesthetics. Cross-cut adhesion of Class 0 ensures rock-solid anchoring. The resin cracking threshold >100µm enables thick-film applications. Linear shrinkage <1% guarantees dimensional stability.

Ceramizable Potential, Serene at High Temperatures
As a ceramizable precursor, IOTA 9118 achieves a ceramic yield of 50-60% at 800°C (60-70% for the cured product), with ceramic density of 1.60-2.00 g/cm³. Clearcoat formulations are recommended for use below 800°C, while pigmented systems withstand up to 1600°C, offering long-term resistance to oxidation and thermal shock. The cured coating is non-combustible and intrinsically safe; its dense cross-linked network provides excellent oxidation and chemical corrosion resistance, with good chemical barrier properties effectively blocking O₂, H₂O, and other gases.

Versatile Curing Methods
IOTA 9118 offers thermal curing (with or without peroxide crosslinkers, above 250°C), platinum-catalyzed hydrosilylation (80-100°C), or UV curing (with cleavable photoinitiators), providing an exceptionally broad processing window to suit diverse production conditions and substrate temperature sensitivities.

From high-temperature flue pipes, engine compartment components, and heat-resistant anti-corrosion coatings for industrial oven interiors, to specialty adhesives, non-flammable composite matrices, and release coatings for glass molds—the application landscape of IOTA 9118 is both vast and deep. Choosing it means you no longer need to compromise between "temperature resistance rating" and "application convenience." This is the professional choice engineered for extreme environments and the universal answer empowering complex substrates.
