High Temperature Ceramic Adhesives up to 1760°C (3200°F)

When extreme heat meets engineering precision, conventional bonding solutions fail. High temperature ceramic adhesives provide a reliable alternative for demanding industrial and research applications.

The ceramic bonding compounds supplied by Kager Industrieprodukte GmbH withstand continuous temperatures up to 1760°C (3200°F), offering exceptional thermal stability, chemical resistance, and electrical insulation properties.


Why Choose High Temperature Ceramic Adhesives?

Industrial high-temp applications require more than heat resistance. They demand dimensional stability, compatibility with refractory materials, and performance under vacuum conditions.

Key advantages:

  • Temperature resistance up to 1760°C (3200°F)
  • Excellent chemical and corrosion resistance
  • Electrically insulating
  • Suitable for ceramic-to-metal bonding
  • Ideal for high-vacuum and furnace environments

These ceramic adhesives are engineered for bonding:

  • Ceramics
  • Metals
  • Graphite
  • Glass
  • Refractory insulation materials

Design Guidelines for Ceramic Adhesives

Successful bonding at extreme temperatures requires proper joint design:

  • Match Coefficient of Thermal Expansion (CTE)
  • Avoid tensile stress – design for compression
  • Optimal bond line thickness: 50–200 µm (2–8 mils)
  • Consider chemical and thermal exposure

Pro Tip: Designing joints that allow compressive loading significantly increases bond durability.

COLDER Cold Air Generator – Powerful Cooling Using Compressed Air Only

The COLDER cold air generator by Kager produces extremely cold air using compressed air only – no electricity and no additional gases required. The system operates based on the Joule-Thomson effect (adiabatic, irreversible expansion), ensuring reliable and energy-efficient cooling.

The COLDER 190-75 SV model generates for example cold air down to −55 °C when connected to a compressed air line or compressor at 7 bar with an inlet air temperature of +20 °C. Installation is simple, maintenance is minimal, and operating costs are low. They are available in 4 different versions.

Typical Applications of COLDER Cold Air

COLDER cold air is widely used for heat elimination in industrial manufacturing processes, especially for:

  • Metal and plastic machining
  • Hard-to-machine materials such as titanium, stainless steel, Inconel
  • High-viscosity materials and thermoplastics
  • Dry machining, e.g. magnesium alloys

Targeted cooling of tools or workpieces results in:

  • increased cutting speeds
  • extended tool life
  • improved process stability

COLDER is also highly effective for cooling:

  • metal molds
  • printed circuit boards (PCBs)
  • semiconductors
  • electrical control and switching components

Precise Temperature Control & Stability

The outlet air temperature is adjusted via a control screw and monitored using a thermometer or sensor. With constant inlet pressure and temperature, the COLDER maintains the cold air temperature within ±0.6 °C, ensuring maximum process reliability.

⚠️ Important: The supplied compressed air must be free of oil and moisture to guarantee optimal performance and durability. They are maintenance-free.
