Cortec Launches a Micro-Corrosion Inhibiting Coatings Palette to Tackle High Moisture Conditions
Cortec has launched Micro-Corrosion Inhibiting Coatings, a palette of coatings for corrosion protection in high humidity conditions.
To tackle the issues that can arise when applying a coating in high moisture conditions, such as those connected to durability over time and the curing process, Cortec has launched Micro-Corrosion Inhibiting CoatingsTM, a palette of coatings options specifically developed to face elevated moisture problems.
The Micro-Corrosion Inhibiting CoatingsTM PaletteTo tackle the issues related to the curing process in high humidity conditions, Cortec has developed VpCI®-396, a solvent-based moisture cure urethane that can be used as a direct-to-metal (DTM) primer, and in some cases a topcoat. It provides protection in harsh, outdoor, unsheltered applications and cures best when applied under relative humidity of 20-80% with temperatures ranging from 32-120 °F (0-50 °C). This makes it a good option for ballast tanks or structural steel and tanks in a chemical- or water-vapor rich industrial environment.
VpCI®-396 can be used over CorrVerter® Rust Converter Primer on previously rusted surfaces. CorrVerter® is a fast-drying water-based one-coat system that converts these rusted surfaces to a hydrophobic passive layer and prevents further rusting through the unique formulation of chelating agents and PVDC resins. It offers 5B adhesion and eliminates the need for blasting in situations where this is not convenient or allowed.
A coatings system of CorrVerter® top-coated with VpCI®-396 is suitable for immersed structures such as storage tanks or even holding tanks containing hydrocarbons or high salinity solutions. This coatings combination is also excellent for application over rusty surfaces on wind tower base bolts, electrical poles, and other outdoor structures in high humidity environments.
The palette also includes VpCI®-395, a water-based epoxy primer that is good for immersion applications on rust-free surfaces. It is a fast drying, two-component system that can be applied DTM and also provides protection in harsh, outdoor, or unsheltered applications. VpCI®-395 should be coated with a urethane such as VpCI®-396 for enhanced durability.
