In aerospace, energy propulsion, and high-end industrial manufacturing, the limits of materials are constantly being challenged. When traditional organic coatings fail at a few hundred degrees Celsius, and the complex processes of specialty ceramics constrain design innovation, how do we protect the core components operating in flames and extreme environments?

We present the breakthrough solution: IOTA OPSZ 1800 Thermosetting Organosilicon Polysilazane Resin. This is more than a coating; it is an intelligently transforming Polymer-Derived Ceramic (PDC) precursor. It takes the form of a liquid resin for the convenient application of polymeric materials, then uses high temperature as a key to grow in situ a dense ceramic armor on the substrate surface, capable of withstanding instantaneous ultra-high temperatures up to 1800°C, perfectly merging processing convenience with performance limits.

Core Advantage One: Exceptional Process Flexibility
The product employs a low-viscosity, solvent-free system with an ultra-high solid content of 99.99%, ensuring an extremely dense coating while maintaining ease of flow and application. Its curing process is highly flexible: in standard mode, rapid curing is achieved upon heating to 200°C; by adding trace amounts of peroxide initiators, the curing temperature can be significantly reduced to 100-180°C, allowing for flexible and controllable curing completion within 1 to 90 minutes, offering you versatile choices that balance efficiency and energy consumption.

Core Advantage Two: Intelligent Polymer-to-Ceramic Transformation
This is the disruptive essence of IOTA OPSZ 1800. When the coating is heated above 425°C, the material undergoes profound molecular reconstruction, transforming precisely and in situ from an organic polymer into a high-performance inorganic ceramic coating. This transformation process grants it : the coating can operate long-term in high-temperature environments above 1000°C, with an astonishing instantaneous peak temperature resistance reaching 1800°C, coupled with excellent thermal shock resistance, oxidation resistance, and corrosion resistance.

Core Advantage Three: Broad Application Compatibility
As a precursor, it is compatible with a wide range of solvents including alkanes, aromatics, ethers, ketones, and esters, with a typical addition rate of 10-60%, making it easy to formulate and integrate. Whether serving as an ultra-high temperature resistant ceramic coating for aero-engine hot-section components or hypersonic vehicle thermal protection systems, a thermally stable anti-corrosion coating for semiconductor heat treatment equipment or new energy battery modules, or a non-stick coating for specialized metallurgical molds and high-temperature reactor linings, IOTA OPSZ 1800 provides a one-stop solution from liquid resin to high-performance ceramic.

Choosing IOTA OPSZ 1800 means adopting a future-oriented materials strategy—it seamlessly combines the superior molding freedom of polymers, flexible and mild curing processes, and the unmatched  of ceramics through intelligent transformation. Let us collaborate to safeguard every extreme technological challenge with the evolution of materials.
