High-temperature Protection
Protect metal parts against heat, oxidation and thermal cycling with polysilazane-based coating systems. We don’t promise a universal result — we recommend a specific material for your substrate and operating temperature, confirmed by documentation and a sample.

The challenge
Recognise your situation — and what it costs when heat protection fails.
Heat, oxidation and thermal cycling attack metal surfaces continuously in high-temperature service. When a protective layer fails, the cost is not just recoating — it is downtime, part replacement and safety risk.
Conventional organic paints have limits at elevated temperatures. Silazane-based systems form a dense protective layer designed for longer service in hot, oxidising conditions — the right grade and film build are confirmed during technical review.
Typical situations
Exhaust and combustion systems — sustained heat and hot gases
Furnaces, kilns and burners — high-temperature process heat
Outdoor and industrial equipment exposed to thermal load
Heat exchangers, ducting and process equipment
How the protection works
Ceramic protection layer
Dense barrier against heat, oxidation and thermal cycling

FAQ
Common questions about high-temperature coating projects.
Can the coating be applied to an already oxidised surface?
Surface preparation requirements — including scale and oxide removal — are defined in the Application Guide. The condition of your surface is assessed during technical review.
How is this different from conventional heat-resistant paint?
Silazane-based systems form a dense ceramic-like layer designed for high-temperature environments. Comparative data for a specific grade is available on request.
How much heat can the protection handle?
Performance depends on the grade, film build and application quality — we validate it on your parts through sample testing rather than promising generic numbers.
Which product should I start with?
Send your substrate, operating temperature and process — our team will recommend a grade and provide the TDS. Custom formulation is possible subject to technical review.
Can I test before committing to volume?
Yes — sample support is available for qualified B2B projects after a short technical review.
What about MOQ and pricing?
Both depend on the grade, packaging and volume — include your estimated quantity in the request and a quotation follows the technical review.

About high-temperature protection
High-temperature coatings protect metal assets against heat, oxidation and thermal cycling in industrial environments. Polysilazane-based systems form a dense protective layer for hot service conditions.
Product selection depends on the substrate, operating temperature and application process. Technical data sheets, application guides and sample support are provided on request for each product grade.
