When aerospace engine combustion chambers face the test of 1600°C , and specialized metallurgical furnace linings endure thermal shock in extreme environments, traditional protective materials are confronting unprecedented performance limitations. Oxidation corrosion, thermal stress fatigue, and structural instability under high-temperature conditions have become critical bottlenecks restricting the reliability and service life of high-end equipment.

The emergence of IOTA OPSZ 1800 Organopolysilazane marks a revolutionary breakthrough in high-temperature protection technology. This innovative heat-curable coating resin not only maintains long-term operational temperatures above 1000°C and withstands peak temperatures up to 1800°C, but also possesses intelligent ceramic transformation capabilities—when temperatures reach above 425°C, the polymer begins transforming into a ceramic structure; after exceeding 700°C, it  a dense ceramic coating, forming a natural thermal barrier.

The revolutionary technological breakthrough extends further. OPSZ 1800 adopts a solvent-free system with an ultra-high solid content of 99.99%, ensuring zero VOC emissions during application and full compliance with the strictest environmental standards. Its low viscosity ensures uniform coating coverage on complex geometric surfaces, forming a complete and defect-free protective layer. In terms of curing processes, the product offers exceptional flexibility: rapid curing at 200°C under conditions; with the addition of free radical initiators, the curing temperature can be reduced to 100-180°C, with curing times shortened to 1-90 minutes, significantly enhancing production efficiency.

Even more noteworthy is that this system allows precise  of the final ceramic phase composition through formulation adjustments and process optimization. In nitrogen or argon atmospheres, it can generate composite structures of SiC and Si₃N₄; in ammonia, it primarily forms Si₃N₄; while under air conditions, it yields SiBOCN ceramics—truly realizing the design philosophy of "one material, multiple properties."

Today, IOTA OPSZ 1800 has been successfully applied in  fields such as aerospace thermal protection systems, new energy battery thermal management, industrial furnace linings, and specialized chemical equipment. Against the global backdrop of carbon peaking and carbon neutrality, this efficient and energy-saving high-temperature protection solution is becoming a vital technological  for promoting  industrial upgrading.

Choosing IOTA OPSZ 1800 is not merely selecting a material—it is embracing a future-oriented philosophy of high-temperature protection, where extreme temperatures become a stage to showcase technological prowess rather than a boundary limiting innovation.
