thermal insulating coating


nC® ProTherm is a series of sprayable and brushable thermal insulating coatings. With additional properties as acoustic insulation in dB-X, Safe-Touch, fire retardancy in Fire-X and corrosion passivation in CUI-X, you can always find the suitable thermal insulating coating for your situation.

With a sol-gel nanotechnology basis, the thermal insulating coating aims for long lasting lifetime cycles of more than 15 years outdoors, and life-long expectancy indoors. Because of the ability to insulate with a very thin layer of coating, the nC® ProTherm coatings offer space saving and cost reducing at a high degree of insulation with an U-value at 4,2 W/(m²K) at 6 mm, and a lambda (λ)-value at 0,040 W/(mK). It is moist repelling and UV-resistant. Of course, it keeps heat and cold in place.

nC® ProTherm ISO-X is a thermal insulating coating addressing both cold and heat issues. You can apply it on brick, stone, wood and concrete. Before application, the dry component A must be mixed together with rsin component B. Use a mixer to prepare a 1:4 ratio powder/resin mixture. At this point, apply ISO-X by brush, roller or spraygun. It shows a stucco-like, relief finish. nC® ProTherm ISO-X can be applied in one layer, between 3mm up to 18 mm. Obviously, nC® ProTherm ISO-X is available in all colours.

  • Use safety glasses. Protect hands and skin from exposure using gloves and appropriate clothing.
  • Ensure adequate ventilation.
  • Obviously, substrate must be free from grease, dirt or dust before application of thermal insulating coating.
  • 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 3 minutes.
  • Subsequently, do NOT use any thinner.
  • Use brush, roller or airgun/spraygun for application.
  • Film thicknesses can be varied from between 3mm to 18mm WFT.
  • Cross layer-application is recommended. At this point wet-in-wet.
  • Measure WFT during application. Product expands up from between 5% to 15% during application.
  • nC® ProTherm ISO-X will decrease 10% in thickness during curing time.

Table for curing times, at ambient temperature of 20° C and 60% humidity:

Surface Curing time
Sandstone, brick, gypsum, natural wood 12 hrs
Concrete, pressed wood, synthetics, glass 24 hrs / 48 hrs
Product can be exposed to full rain after 12 hours
  • Let surface dry in for at least 6 hours before forced drying by means of blower or heater at 55° C max.
  • Surface can be painted over.
  • Clean brushes, rollers, nozzles with water immediately after any stop.
  • Wash hands and face after every stop.


  • Do not use as a final floor covering.
  • In case of long-term or life-long submersion, only install in combination with nC® ProTherm H2O finish.
  • Do not install over poor surfaces, such as those with flaking paint, grease or other contaminates.
  • Do not allow application during freezing temperatures.
  • Do not rely on visual measurement for coating thickness. Always use a wet film thickness (WFT) and/or dry film thickness (DFT) gauge in several areas to ensure proper application thickness.


  • Never use pressure to empty drums.
  • Dispose of contents/container in accordance with local/regional/national/international regulations.
  • nC® ProTherm ISO-X has a shelf life of 6 months.
