fire retardant coating

DESCRIPTION

Based on covalent bonding nanotechnology, the fire retardant coating nC® ProTherm Fire-X system is designed for thermal insulation, IR-reflection and corrosion passivation. Fire-X has a long lasting lifetime cycle of more than 20 years outdoors, and life-long expectancy indoors.

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).

It provides Safe Touch 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 260°C. Because nC® ProTherm Fire-X is a fire retardant coating, it can withstand temperatures up to 900°C for 24 hours without deterioration. nC® Fire-X is hydrophobic and chemical resistant. It keeps heat and cold in place.

CUI

In order to prevent CUI (Corrosion Under Insulation), you can order the nC® ProTherm Fire-X coating  with a corrosion passivating primer. The primer surpasses any corrosion protection coating available as it is based on surface 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. Because of the chemical bonding, the primer can withstand welding temperatures up to 1.500°C, shockloads and chemicals. By the same token, the fire retardant coating suits all materials.

The covalent bond offers a flexible protection for both nC® Fire-X as well as the nC® primer. It will shrink and expand along with the substrate material during ambient temperature changes. This way the fire retardant coating will not crack, as mechanically adhered coatings do. The layer itself offers the look-and-feel of a hard-coat. Both wall or panel, as well as the metal and coating are now immune for elevated temperatures, salt, water, chemicals or oxygen. As the cold alloy primer bonds with the metal, it builds a matrix inside the metal surface and withstands abrasion as never seen before. The primer will protect metals against corrosion for more than 20 years.

Because the nC® ProTherm Fire-X primer is resistant against welding temperatures, it will not get damaged.

nC® ProTherm Fire-X fire retardant coating is applied by knife, roller or spraygun. It shows a stucco-like, relief finish. nC® ProTherm Fire-X can be applied in one layer, between 3mm up to 18 mm and is a fast drying solution. nC® ProTherm Fire-X is available in all colours.

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

Surface Curing time
All materials, indoor 12 hrs
All materials, outdoor 24 hrs / 48 hrs, depending on temperature and humidity
Product can be exposed to full rain after 12 hours. Full cure after 7 days
  • 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 knifes, nozzles with water immediately after any stop.
  • Wash hands and face after every stop.

LIMITATIONS

  • Do not use this corrosion under insulation coating as a final floor covering.
  • To prevent corrosion under insulation: In case of long-term or life-long submersion, only install in combination with nC® ProTherm H2O finish.
