In aerospace, industrial heavy-duty anti-corrosion, and specialty composites, the limits of surface protection are constantly being redefined. IOTA 9118, featuring vinyl as its active functional group, is specifically engineered for high-performance, high-temperature coating systems. It combines the processability of liquid polysilazane with the ultimate heat resistance of ceramics, delivering a full-chain solution from liquid application to ceramic protection.

Data-Proven Excellence
IOTA 9118 is a pale yellow transparent liquid with ultra-low viscosity of 10-40cp, ideal for spraying, brushing, dipping, or spreading. Purity >99%, molecular weight 1200-1400, density 0.98-0.99 g/cm³. The cured coating achieves pencil hardness of 6-7H and water contact angle of 100-105°, combining robust hardness with self-cleaning properties. Visible light transmittance >95%, fully transparent without compromising substrate appearance. Cross-cut metal adhesion is Class 0, ensuring rock-solid bonding. Linear shrinkage <1%, resin cracking threshold >100µm, enabling thick-film applications.

Ceramizable Potential, Serene at High Temperatures
As a ceramizable precursor, IOTA 9118 achieves ceramic yield of 50-60% at 800°C, cured product ceramic conversion of 60-70%, and ceramic density of 1.60-2.00 g/cm³. Clearcoat recommended service temperature <800°C; with pigmented topcoat, it withstands <1600°C. The cured coating is non-combustible, oxidation and corrosion resistant, with good chemical barrier properties against O₂, H₂O, and other gases.

Versatile Curing, Universal Substrates
IOTA 9118 supports thermal curing, platinum-catalyzed hydrosilylation (80-100°C), and UV curing, adapting to diverse production conditions and substrate temperature limits. It exhibits excellent adhesion to metals, alloys, glass, engineering plastics (PP/PC/PVC/PMMA), and existing paint films.

From high-temperature coatings, adhesives, and non-flammable composites, to polymer matrix composites, glass and abrasives, and low-surface-tension easy-clean applications—IOTA 9118 covers a broad spectrum. Choose it to eliminate compromise between thermal resistance and application convenience. Engineered for extreme environments, empowering complex substrates.
