Fire- and heat-resistant silicone glass-ceramic coating from KAGER for industrial high-temperature applications
When conventional paints and coatings reach their thermal limits, specialised high-temperature coatings are required. With CP4000-S2-HT, KAGER offers a powerful fire- and heat-resistant silicone glass-ceramic coating designed for the long-term thermal protection of technical surfaces. The black one-component coating withstands continuous operating temperatures of up to 760 °C and also provides excellent resistance to thermal cycling.
Dietzenbach, Germany, August 2026 – High process temperatures, rapid temperature changes and continuous thermal exposure can place extreme demands on metal components, industrial equipment and technical surfaces. Conventional silicone resin paints and powder coatings often reach their performance limits under these conditions.
For demanding high-temperature applications, KAGER Industrieprodukte offers CP4000-S2-HT, a specialised silicone glass-ceramic high-temperature coating. Once cured, the one-component system forms a temperature-resistant protective layer suitable for a wide range of industrial applications.
Continuous high-temperature protection up to 760 °C
CP4000-S2-HT is designed to withstand continuous temperatures of up to 760 °C (1,400 °F). Its thermal cycling resistance extends to as much as 981 °C (1,798 °F).
This makes the coating particularly suitable for components and surfaces exposed not only to high operating temperatures but also to repeated heating and cooling cycles.
The coating can be used as a thermal protective barrier for suitable technical surfaces, components and assemblies. High-temperature surface protection can help protect thermally stressed components, extend service life and reduce maintenance requirements.
Choosing the appropriate high-temperature coating can therefore contribute to improved process reliability, equipment availability and long-term product quality.
High-temperature coating for a wide range of industries
CP4000-S2-HT can be used across numerous industries and technical applications. KAGER supplies this specialised high-temperature coating for applications including:
- automotive and vehicle manufacturing
- industrial furnace construction
- boiler and plant engineering
- power generation and energy technology
- aerospace applications
- heating and thermal systems
- lighting technology
- chemical and process engineering
- foundries and metal processing
- industrial high-temperature processes
Wherever suitable technical or metal surfaces require long-term protection against extreme temperatures, CP4000-S2-HT can provide an effective coating solution.
One-component system for convenient application
One of the practical advantages of CP4000-S2-HT is its one-component formulation. Unlike multi-component coating systems, no complicated mixing process is required before application.
The black coating has a viscosity of approximately 150 to 500 mPa·s, providing practical handling and application characteristics.
If dilution is required, T-butyl acetate can be used as the thinner.
CP4000-S2-HT can be processed at normal ambient temperatures between approximately 10 °C and 30 °C (50–86 °F). The coating has a drying time of approximately one hour and typically cures at room temperature within 24 to 48 hours.
For longer-term storage, a temperature range of approximately 4.5 °C to 30 °C (40–86 °F) is recommended.

Why professional advice matters when selecting a high-temperature coating
Maximum temperature resistance alone does not determine whether a coating is suitable for a particular industrial application. Other important factors include the substrate material, surface preparation, temperature cycles, environmental conditions, process atmosphere and the required function of the protective layer.
For this reason, KAGER recommends selecting high-temperature coatings according to the specific operating conditions of each application.
The technical specialists at KAGER Industrieprodukte GmbH support customers in selecting suitable heat-resistant coatings and provide advice on application, processing and high-temperature performance.
Another advantage, particularly for R&D, prototype manufacturing, maintenance and small production runs: KAGER can supply many specialised products in small quantities.
