New technology from Hempel improves zinc-rich epoxy primers

Hempel have developed a new technology that they claim improves the corrosion protection of traditional zinc-rich epoxy (ZRE) primers,which can still be applied using the same application techniques. This technology is called AvantGuard® and is said to make the metallic zinc pigment more active by combining it with hollow glass spheres and proprietary activators.
