HEMPADUR AvantGuard® Activated Zinc Primers

HEMPADUR AvantGuard® activated zinc primers use unique AvantGuard® technology to protect industrial structures and equipment in C4, C5 and offshore corrosive conditions. They can be used in a range of industries and applications, from offshore oil & gas platforms to power plants and wind turbines. The product range won NACE’s MP Corrosion Innovation of the Year Award for 2014 in the Coatings and Linings category.

Redefining zinc coating technology

Organic zinc-rich primers have been an established technology since the 1960s. But back in 2007, Hempel’s R&D team discovered that only around one-third of the zinc in a standard zinc epoxy coating has an anti-corrosive effect. Hempel spent around 8,000 hours in the lab re-engineering zinc coating technology in order to find a better solution.

The result is patented AvantGuard® technology, which uses a combination of zinc dust, hollow glass spheres and a proprietary activator to activate more of the zinc in the coating. As a result, coatings with AvantGuard® technology provide significantly better galvanic protection than zinc epoxies without AvantGuard®. In addition, this gives the coatings superior mechanical strength, while increasing ease of application.
