fire retardant coating


With a covalent bonding mineral and ceramic technology, the fire retardant coating nC ProTherm FIRE-X Advanced Ceramics system is ready for thermal insulation, IR-reflection and fire protection. Firstly, because of the ability to insulate with a very thin layer of coating, nC® ProTherm Fire-X offers space saving and cost reducing protection 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). As the ceramic particle structure provides a dense, slightly  flexible layer it provides extra characteristics as non-scaling, non-fouling and chemical resistance. nC® ProTherm FIRE-X Advanced Ceramics is an exceptional versatile solution.

FIRE-X Advanced Ceramics has a very long lasting lifetime cycle of more than 25 years in- and outdoors, making it not only versatile, but also very cost-effective.

OPTIONAL: nC® ProTherm FIRE-X Advanced Ceramics is available also in an anti-mold and anti-algae version and remains a fire retardant coating.

Because of the ability to create a barrier and insulate with just a thin layer of coating, nC® ProTherm FIRE-X Advanced Ceramics offers space saving and cost reducing protection at a high degree of insulation. It provides Safe Touch and/or fireproof surfaces to panels, walls and all kinds of separators and is capable of reducing surface temperatures at Delta T-values varying between 80°C up to 1000°C, depending on DFT.

Tests show that a layer of 5mm of nC® ProTherm FIRE-X Advanced Ceramics fire retardant coating can avoid the meltdown of several construction materials during an intense fire. It keeps heat out, thus not endangering the lives, assets or products at the other side of the fire or heat source.

In order to prevent CUI (Corrosion Under Insulation), you can order the nC® ProTherm FIRE-X coating with nC’s corrosion passivating primer. The nC® Nano Corrosion Passivator Primer surpasses any corrosion protection coating available as its basis is surface bonding nanotechnology (sol-gel). The system will prevent metals from corroding. It will stop already present corrosion. It can be applied on corroded surfaces without the need for sandblasting or chipping. You can apply nC® ProTherm FIRE-X Advanced Ceramics on top of that immediately.

This makes it a very fast, cost-effective and environment friendly solution. Because of the chemical bonding, the primer can withstand welding temperatures up to 1300°C, shockloads and chemicals. This covalent bond offers a flexible protection. It will shrink and expand along with the substrate material during ambient temperature changes. This way the coating will not crack, as mechanically adhered coatings do.

Because both the nC® ProTherm FIRE-X Advanced Ceramics as well as the primer are resistant against welding temperatures, they will not damage during welding.

Weight adjusted on each other, nC® ProTherm FIRE-X Advanced Ceramics is delivered together in separate containers carrying dry mineral ceramic powder and a wet component resin. It offers the look-and-feel of a hard-coat. All materials like metal, concrete, wood, polystyrene, polyester etc. including rockwool acting as a wall or panel or tube, will become immune for extreme heat, salt, water, chemicals, oxygen, biofouling and scaling using the fire retardant coating.

nC® ProTherm FIRE-X Advanced Ceramics can be applied with an airless spray-system, a rotor-stator spray system. Touching-up or small repairs can be done by knife, brush or roller. nC® ProTherm FIRE-X Advanced Ceramics can be applied in one layer, between 4mm up to 15mm for most applications, and is a fast drying solution. nC® ProTherm FIRE-X is available in white and grey. Paint it over for aestethic purposes.

  • Suitable for lively and light flexible surfaces.
  • nC® ProTherm FIRE-X Advanced Ceramics fire retardant coating can withstand surface temperatures up to 1300 ° C
  • The ambient temperature during application must be between 4 ° C and 35 ° C.
  • DO NOT apply if the humidity is higher than 90%.

  • Use safety goggles during preparation and application of nC® ProTherm FIRE-X Advanced Ceramics.
  • Protect hands and skin from exposure with gloves and appropriate clothing.
  • Although the fire retardant coating is solvent-free, ensure adequate ventilation, especially when spraying.
  • The surface of host material must be free from grease, dirt or dust.
  • The surface of host material must be free from loose rust and / or loose paint.
  • In case of corroded parts, remove loose rust and apply nC® Nano Corrosion Passivator Primer to the corroded area. Sandblasting, sanding or chipping is then not necessary.
  • Mix wet component B for 5 minutes before adding dry component A. Use (industrial) mixer with at least 7 cm wide mixing blades.
  • Add dry component A 12% weight gradually (in a timespan of 10 minutes) to resin component B 88% weight. Mix for at least 3 minutes after dry mix is completely added.
