Formulators looking to enhance the corrosion protection of increasingly popular water-based coatings systems can now use Cortec’s M-120, a water-based corrosion inhibitor additive that does not contain heavy metals. M-120 can be used alone or in conjunction with other inhibitors to increase the corrosion protection abilities of both water-based and solvent-based systems. It is recommended for use in acrylic and alkyd resin systems.
M-120 protects both carbon steel and aluminum. It contains contact corrosion inhibitors that eliminate in-can corrosion, inhibit flash rust, and provide long term protection to the metal substrate. The additive does not contain any heavy metals such as zinc phosphate, chromates, or barium. M-120 comes as an off-white/beige colored paste that can be added to coatings formulations at recommended loading levels ranging from 1.0-3.0% based on total formula weight.
Cortec’s M-120 additive contains a special blend of corrosion inhibitors that protect against corrosion by forming a microscopic inhibitor layer along the contours of the metal substrate. Traditional coatings rely on sacrificial metals such as zincs and chromates for corrosion protection. Due to their large particle sizes, these inhibitors leave gaps that make it easier for corrosion to begin in micro-cavities. In contrast, M-120
contains inhibitors that have an attraction to metal and desire to conform to the intricacies of metal surfaces, providing a protective layer in micro-cavities for fuller inhibitor coverage.
Market demand is increasingly shifting to the use of more water-based systems that have a lower environmental impact and are much easier to clean up than solvent-based systems. M-120 can help formulators meet these demands by delivering a water-based corrosion inhibitor that does not contain heavy metals but provides a microscopic protection layer on metal surfaces. M-120 also has the flexibility to provide an added level of corrosion protection for cases where solvent-based systems are still preferred.
