nC® ProTherm dB-X

nC® ProTherm dB-X thermal insulating coating


Based on sol-gel nanotechnology, the nC® ProTherm dB-X coating system is designed for thermal and acoustic insulation, as well as fire retardancy. dB-X has a long lasting lifetime cycle of more than 15 years outdoors, and life-long expectancy indoors.


Because of the ability to insulate with a very thin layer of coating, nC® ProTherm dB-X offers space saving and cost reducing protection at a high degree of thermal insulation. Thermal conductivity λ10 mW/(m·K) 56 and Thermal resistance R10 m2K/W 0.2409 at 10mm, at a lightweight density of 350 gr/m³.


Limiting the transmission of sound from one area to another requires material that encloses the source of the noise and forms a barrier that absorbs vibrations between the source and the adjacent areas. There are two different types of sound: airborne and impact. Airborne noises come from voices, machines, etc. Impact noise includes vibrations from machines, exhausts, your washer and dryer or rotating propellers from other ships conveyed through the water to our hull. nC® ProTherm dB-X reduces both airborne and impact noises. If your walls and hull are properly insulated, you’d probably be surprised at how much quieter noises from your neighbor or outside seem!


nC® ProTherm dB-X is suitable for application on metal, synthetics, brick, concrete and wood. Apply dB-X preferably with airgun. For a rougher surface use brush, roller or knife. It shows a stucco-like, relief finish. Apply nC® ProTherm dB-X in one layer, between 5mm up to 12 mm. It is available in all colours and allows painting over.

Values taken from report ZAE Bayern, Germany (Centre for Applied Energyresearch). Chart translates as:

  • Lambda value λ (w/mK) = 0.045
  • U Value = 0,75 W/m²K


  • Suitable for indoor and outdoor surfaces.
  • Apply on stone, concrete, wood, rooftiles or gypsum only.
  • nC® ProTherm dB-X operates on surfaces with internal temperatures ranging from -50° C up to 150° C.
  • A nC® ProTherm dB-X coat can withstand surface temperatures of up to 180° C for short periods of time.
  • Never expose a nC® ProTherm dB-X coat to surface temperatures of more than 150° C.
  • During preparing and application of nC® ProTherm dB-X, use safety glasses. Protect hands and skin from exposure using gloves and use appropriate clothing.
  • Although free from solvents, please ensure adequate ventilation, especially when spraying.
  • Substrate must be free from grease, dirt or dust.
  • Substrate temperature must be between 4° C and 75° C.
  • Ambient temperature must be between 4° C and 35° C.
  • Do not apply when ambient humidity exceeds 90%.
  • Mix dry component A 25% weight to resin component B 75% weight. Use (industrial) mixer.
  • Mix for at least 5 minutes.
  • Do NOT use any thinner.
  • For rough surface: Use brush, roller or knife.
  • For smooth surface use airgun/spraygun suitable for low viscosity stucco, for application.
  • One-coat film thicknesses can be varied from between 5mm to 12mm WFT.
  • Cross layer-application is recommended, wet-in-wet.
  • In case of rolling a rough surface will appear. If a smooth surface is required, please wet the finished surface with a low volume water mist sprayer (not a garden hose) and move a wet metal profile of about 120 cms long over the surface to make it smooth.  
  • Measure WFT during application. Product expands up from between 5% to 15% during application.
  • nC ProTherm dB-X will decrease 10% in thickness during curing time.



Sandstone, gypsum, brick, natural wood
