High performance water based coating with nano vapor corrosion inhibitors

 
The use of single component water-based coatings for protection of metal substrates continues to grow due to low odor, health and safety advantages, easy cleanup and environmental friendliness. The challenge continues to be finding alternatives to traditional heavy metal type corrosion inhibitors which tend to rely on passivation or sacrificial cathodic protection. Additionally, ongoing regulatory developments continue to tighten the usage of products containing these heavy metals, thus forcing the need for alternative technologies. The use of nano vapor phase corrosion inhibitors provide an attractive alternative by adsorbing onto the metal substrate and filling the voids or microcrevices of the substrate and preventing corrosion from starting or growing once the surface of the coating has been damaged. This technology has been proven effective at DFTs of 1 mil(25 microns).
