From radar equipment to aerospace instruments, one material connects the entire industrial protection chain

In the industrial field, the three major problems of high temperature, corrosion, and friction have always plagued equipment maintenance. Recently, an organic polysilazane material called IOTA 9150, with its composite properties of "resisting 1000°C high temperature + anti-chemical erosion + low shrinkage rate", has opened a new chapter in industrial protection in aerospace, petrochemical, electronic manufacturing, and other fields.

Technological Breakthrough: The "Anti-Corrosion Code" of Three-Dimensional Network Structure

The core competitiveness of IOTA 9150 lies in its cured silazane three-dimensional network. According to material scientists, this network is interwoven with Si-N bonds and Si-O bonds, which can not only be used for a long time below 300°C but also maintain structural stability in short-term working conditions of 1000°C—this is due to the high thermal stability and oxidation resistance of Si-N bonds. Test data from an oil pipeline shows that after 3 years of service in a sulfur-containing oil and gas environment, the surface corrosion rate of the pipeline coated with 15μm IOTA 9150 is 80% lower than that of traditional epoxy coatings.

More critically, it has an extremely low linear shrinkage rate (<1%). In the thermal cycle test, after 500 cycles of repeated temperature changes from -40°C to 300°C, the coating did not crack or peel off, making it irreplaceable in scenarios with drastic temperature differences such as aero-engine blades and spacecraft thermal protection components. "Traditional ceramic coatings are resistant to high temperatures but are brittle and prone to cracking, while IOTA 9150 balances hardness and flexibility," commented an expert from an aerospace materials research institute.

Application Expansion: A "Master Key" for Protective Scenarios in Multiple Industries

In the electronics industry, the transparency (visible light transmittance >95%) and insulation of IOTA 9150 make it a new choice for circuit board protection. After a chip packaging company applied a 20μm coating, it not only solved the problem of moisture erosion on circuits but also achieved automated spraying due to its low viscosity, increasing production efficiency by 60%. In the glass deep processing industry, when the material is used as a mold coating, it can reduce the friction coefficient during glass cutting, extending the mold life by more than 2 times.

In the marine engineering field, a port machinery manufacturer applied IOTA 9150 to the surface of crane steel structures, and with a 120°C heating curing process, the formed 100μm coating showed no rust after 1000 hours of testing in a salt spray environment. This provides a lightweight solution for long-term anti-corrosion in marine engineering—compared with traditional heavy anti-corrosion coatings, its density is only 1.3g/ml, and the weight is reduced by more than 40%.

Construction Innovation: "Low-Temperature Curing + Compatibility" Reduces Industrial Application Thresholds

Considering the complexity of industrial scenarios, IOTA 9150 has been designed with targeted compatibility in construction. It can be mixed with non-polar solvents such as alkanes and ketones in any proportion, and can also be compounded with materials such as epoxy resins and silicone resins. When mixed with silicone resins, it not only shortens the curing time but also further improves the coating hardness. A composite material manufacturer stated that after adding this material as an additive to the resin system, the flexural strength of the composite material increased by 15%, and the heat distortion temperature rose by 20°C.

For on-site construction scenarios, the material supports both room-temperature curing and heating-accelerated curing modes. In emergency repairs, a protective layer can be quickly formed through room-temperature curing; in conventional construction, heating to 120°C-180°C can shorten the full curing time from 24 hours to 2-5 hours, greatly improving industrial maintenance efficiency. In addition, its universal adhesion to substrates such as metals, plastics, and glass avoids the cumbersome process of traditional coatings requiring different formulas for different substrates.

Industry Outlook: Greenization and Functional Integration Drive Market Expansion

As environmental regulations become stricter, the "low VOC emission" characteristic of IOTA 9150 has also gained advantages. Its solid content is ≥99%, and only a small amount of solvent is needed for dilution, which can reduce volatile organic compound emissions by more than 80% compared with solvent-based coatings. An environmental evaluation agency pointed out that the inert coating formed after the material is cured can be removed by strong alkali solutions (such as 10% sodium hydroxide), facilitating equipment maintenance and material recycling, which is in line with the development trend of the circular economy.

The industrial protective materials market is evolving towards "high performance, multi-function, and easy construction". The innovation of IOTA 9150 based on silazane chemistry not only solves the performance bottlenecks of traditional materials but also reduces application thresholds through technological integration. The industry predicts that with the increase in its penetration rate in high-end manufacturing, this material is expected to become a landmark product in the industrial protection field within the next 3-5 years, promoting a comprehensive upgrade of industry technical standards.
