Cortec® introduces the next generation of high-performance coatings
Article Type: New materials and equipment From: Anti-Corrosion Methods and Materials, Volume 61, Issue 5
Water-borne Anticorrosion Coatings have gone through many stages of evolution and improvements in recent years. More stringent environmental standards are pushing the creation of water-borne coatings for corrosion protection forward. Recent innovations from Cortec Corporation’s Laboratory enable us to offer new, novel coatings for multi-metal protection. This next generation of high-performance water-based acrylic coatings has improved barrier performance and enhanced stability, which provides superior corrosion defense in harsh outdoor, unsheltered applications. CorShieldTM VpCI®-386 HP’s unique Nano-VpCI® formulation contains a mixture of non-toxic organic inhibitors and pigments that offer extended coating protection, which strongly competes with heavy metal zinc-rich primers and paints. Cortec’s special combination of additives provides a nanoparticle composite polymer barrier that significantly retards the reaction of metal ionization by ion scavenging and passivation.
Economical, environmental-friendly and easy-to-handle CorShieldTM VpCI-386 HP is much more effective than most conventional coatings because the corrosion resistance has been improved by replacing traditionally used toxic materials with more effective, non-toxic, heavy-metal-free corrosion inhibitors. This safer to use composition eliminates worker exposure to organic solvents and of fire hazards in confined areas. CorShieldTM VpCI-386 HP provides a fast-drying primer/topcoat film that forms a tough, non-flammable, protective barrier that was developed to protect in both indoor and outdoor conditions. It bonds to metal surfaces, defending against corrosive electrolytes and aggressive environments.

CorShieldTM VpCI-386 HP is recommended for a variety of applications, especially where the uses of toxic materials are of concern. The product is thermally stable when dried from −150-350°F (−78-180°C) and is ultraviolet-resistant giving optimal outdoor performance without cracking or chipping upon prolonged exposure to sunlight. VpCI- 386 HP can be used as a topcoat/primer or used as a topcoat with Cortec VpCI-374 as a primer. VpCI-386 HP can be applied by spray, roll, brush or dip. It dries to touch in 40 minutes at 77°F (25°C) and is fully cured in seven days at 77°F (25°C). It is available in 5-gal (19 L) pails, 55-gal (208 L) metal drums, liquid totes and bulk. Available colours are white, grey and yellow (Figure 1).
