nC® NCP Cold Alloy

nC® Nano Corrosion Passivator Cold Alloy


nC® Nano Corrosion Passivator Cold Alloy (NCP CA) is based on surface bonding nanotechnology (sol-gel). The system will prevent metals from corroding. Both new or blasted metals (ferro or non-ferro) can have this treatment which performs equal to galvanized or hot-zinc steel. If sandblasting, hydrojetting, chipping or sanding down is no option on corroded areas of steel, please use nC® NCP Primer first.


 NCP CA is applied by brush, roller or sprayer, without the need for a primer on new or blasted steel.  This makes it a very fast, cost-effective and environment friendly solution.


nC® Nano Corrosion Passivator Cold Alloy develops a cold alloy matrix within the metal surface. This offers a flexible protection, making metals immune for ambient influences like elevated temperatures, salt, water, chemicals or oxygen.


The cold alloy bonds with the metal and withstands abrasion. Because of the chemical bonding, it can withstand welding temperatures up to 1300°C.

Another advantage of the chemical bonding is that potential-differences cannot cause electrical currents in the surfaces, thus preventing galvanic corrosion. Once sealed or painted over, it will protect metals against corrosion and chemicals for more than 15 years.
