nC® ProTherm CRYO-X

nC® ProTherm CRYO-X thermal insulating coating


nC® ProTherm is a series of sprayable and brushable thermal insulating coatings. The series has additional properties as acoustic insulation, safe-touch, fire retardancy, high heat resistance and corrosion passivation in individual nC® ProTherm variations. This enables you to always find the suitable nC® ProTherm solution for your situation.


Based on sol-gel nanotechnology, the nC® ProTherm CRYO-X coating system is designed for thermal insulation, Safe Touch and corrosion passivation. CRYO-X has a long lasting lifetime cycle of more than 10 years outdoors, and life-long expectancy indoors.


Because of the ability to insulate with a very thin layer of coating, nC® ProTherm CRYO-X offers space saving and cost reducing protection at a high degree of insulation. Thermal conductivity λ10 mW/(m·K) 56 and Thermal resistance R10 m2K/W 0.2409 at 10mm, at a lightweight density of 445 gr/m³. The coating is hydrophobic and chemical resistant. It keeps heat and cold in place.  


In order to prevent CUI (Corrosion Under Insulation), the nC® ProTherm CRYO-X coating is equipped with a corrosion passivator. This corrosion passivator surpasses any corrosion protection coating available as it is based on surface covalent bonding nanotechnology (sol-gel). The system will prevent metals from corroding. It will stop already present corrosion.


Both new or blasted metals, as well as already corroded metals (ferro or non-ferro) benefit from this treatment, without the need for chipping or blasting beforehand. This makes it a very fast, cost-effective and environment friendly solution.


The covalent bond offers a flexible protection as it will shrink and expand along with the metal during ambient and internal temperature changes. This way the coating will not crack, as mechanically adhered coatings do. The layer itself offers the look-and-feel of a stucco-coat. Both metal and coating are now immune for deep freezing temperatures, salt, water, chemicals or oxygen.


nC® ProTherm CRYO-X is preferably applied by spraygun. It can also be applied by brush, roller or knife. It shows a stucco-like, relief finish. It can be applied in one layer, between 3mm up to 12 mm and is a fast drying solution. nC® ProTherm CRYO-X is available in white. All colours available for orders exceeding 250kg. nC® ProTherm CRYO-X can be painted over.

  • U Value = 0,75 W/m²K


  • Suitable for indoor and outdoor surfaces.
  • Apply on metals, stone, concrete, wood, rooftiles or glass.
  • nC® ProTherm CRYO-X operates on surfaces with internal temperatures ranging from -160° C up to 120° C.
  • A nC® ProTherm CRYO-X coat can withstand surface temperatures of up to 150° C for short periods of time.
  • Never expose a nC® ProTherm CRYO-X coat to surface temperatures of more than 150° C.
  • During preparing and application of nC® ProTherm CRYO-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.
