• Hempel launched HEMPADUR AvantGuard, a portfolio of three new anticorrosive zinc primers designed for C4 and C5 corrosive conditions. Based on new patented AvantGuard technology, the primers are significantly longer lasting than zinc epoxies without AvantGuard but can be applied with the same application techniques. Zinc epoxies are used in a range of industries to protect industrial structures and equipment in highly corrosive environments where saltwater and high humidity corrode unprotected steel. However, back in 2006, Hempel made a discovery: only around one-third of the zinc in a standard zinc epoxy has any anticorrosive effect. After approximately 7,000 hours in the lab, Hempel said that it found a solution. AvantGuard uses hollow glass spheres and a proprietary activator to activate more zinc in the coating. The resulting coating reportedly delivers higher galvanic protection than zinc primers without AvantGuard technology and also enables barrier and inhibitor protection. The formulation also improves the coating’s mechanical strength.
