IOTA 9150 polysilazane high-temperature resistant protective coating helps to modify the surface of high-end components


1. The application scenarios of polysilazane materials are continuously expanding
Polysilazane, as an inorganic precursor material, can be solidified and transformed to form a dense SiCN ceramic layer. With excellent thermal resistance and oxidation resistance properties, it has gradually been applied in high-temperature components, anti-corrosion protection, and insulation coatings. Anhui IOTA 9150 polysilazane is a single-component liquid precursor, which is convenient to apply and can be compatible with various processes such as spraying, immersion coating, and brushing, meeting the surface coating requirements of different workpieces.


2. Customer frequent technical questions
Q: Is the coating thickness of IOTA 9150 controllable after curing?
A: The thickness can be adjusted by adjusting the dilution ratio and the number of construction layers. A single construction can control thin coating, and multiple constructions can increase the film thickness. Combining with a reasonable heating and curing program, it can avoid coating cracking.


Q: Can this polysilazane be directly used on metal substrates?
A: For metal substrates, it is recommended to do surface degreasing, sandblasting and grinding treatment in advance to improve the roughness of the substrate, effectively enhancing the adhesion of the coating and reducing the risk of delamination in high-temperature environments.


3. Performance of the coating in high-temperature environments
The ceramic coating formed by the curing of IOTA 9150 has good high-temperature oxidation resistance. Under continuous high-temperature conditions, it can prevent oxygen and water vapor from eroding the substrate, reduce component oxidation loss, and extend the service life of components. The coating has high density and low porosity, and the protective effect is stable.


4. Sample testing and selection suggestions
In the early stage of the project, small sample testing can be carried out to verify the compatibility of the substrate, the heating and curing curve, and the tolerance to working conditions. The material storage should be protected from light and sealed, and away from heat sources. If there is a need for small-scale testing, samples can be applied for, and the basic process verification can be completed before scaling up production.
