In extreme high-temperature environments, the endurance and stability of materials directly determine the safety and lifespan of equipment. Traditional coatings are prone to oxidation and peeling under sustained high temperatures, while ceramic coatings, despite their temperature resistance, are limited by complex preparation processes and brittle interfaces. IOTA OPSZ 1800 Heat-Curable Coating Resin redefines material protection solutions for extreme high-temperature working conditions with its unique ceramic transformation capabilities and highly flexible process system, providing unprecedented reliable barriers for industries such as aerospace, energy and chemical engineering, and specialized metallurgy.
IOTA OPSZ 1800 is a solvent-free, high-solid-content system based on organopolysilazane. Its 99.99% solid content ensures the density and environmental friendliness of the coating. The material features low viscosity, allowing easy application on complex surfaces. It can cure rapidly at 200°C, and with the addition of free radical initiators, the curing temperature can be further reduced to 100–180°C, with curing times shortened to 1–90 minutes, significantly improving production efficiency and energy utilization.
The most notable technical highlight of this system is its controllable ceramic transformation capability. When the coating is heated above 425°C, the resin structure gradually transforms into amorphous ceramics. As the temperature continues to rise above 700°C, the coating completes full ceramicization, forming a hard, dense, and highly temperature-resistant ceramic protective layer. This enables the coating to operate stably in environments above 1000°C for extended periods, with a peak tolerance temperature of up to 1800°C, effectively resisting multiple extreme challenges such as high-temperature oxidation, thermal shock, and corrosive media.
By adjusting the pyrolysis atmosphere, the coating can form different ceramic compositions: generating SiC and Si₃N₄ composite ceramics in nitrogen or argon, primarily transforming into Si₃N₄ in ammonia, and forming SiBOCN ceramics in air, achieving "one material, multiple functions" and flexibly adapting to various working condition requirements.
In high-demand fields such as aircraft engine hot-end components, industrial furnace linings, specialized reactor protection, and high-temperature electronic encapsulation, IOTA OPSZ 1800 is becoming the ideal choice to replace traditional coatings. It not only retains the easy application advantages of polymer coatings but also imparts ceramic-level high-temperature performance, truly achieving the perfect unity of process and performance.
Choosing IOTA OPSZ 1800 means embracing a future-oriented high-temperature protection strategy—elevating material limits through intelligent transformation and safeguarding safety and reliability in extreme working conditions.
