nC® ProTherm CUI-XF thermal insulating coating
Based on sol-gel nanotechnology, the nC ProTherm CUI-XF coating system is designed for thermal insulation, Safe Touch and corrosion passivation. CUI-XF 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 CUI-XF 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 500 gr/m³.
It provides Safe Touch surfaces and is capable of reducing surface temperatures of for instance steampipes from 150°C down to 50°C and below. CUI-XF is hydrophobic, corrosion passivating and chemical resistant. It keeps heat and cold in place.
In order to prevent CUI (Corrosion Under Insulation), the nC ProTherm CUI-XF coating is equipped 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 coating withstands shockloads and heavy chemicals.
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 or release from the surface, as mechanically adhered coatings do. The layer itself offers the look-and-feel of a hard-coat. Both metal and coating are now immune for elevated temperatures, salt, water, chemicals or oxygen. As the coating bonds with the metal, it builds a matrix inside the metal surface and withstands abrasion as never seen before. The coating will protect metals against corrosion for more than 20 years.
Because nC® ProTherm CUI-XF is fire resistant, it will protect the integrity of the structures it is applied on against melting down for a very long period of time. This period varies between 8 hours and 48 hours depending on the severity of the fire and the thickness of the coating applied.
nC® ProTherm CUI-XF is applied by spraygun as it keeps the coating airy, thus improving the insulating capacities. It shows a stucco-like finish. If applied by brush, roller or knife, the end result will show a rough surface. nC® ProTherm CUI-XF can be applied in one layer, between 3mm up to 12 mm and is a fast drying solution. nC® ProTherm CUI-XF is available in off white. Available in all colours if ordered in quantities above 140 kg.
