HEUCOPHOS® ZPO

Technical Datasheet | Supplied by Heubach

HEUCOPHOS® ZPO by Heubach is an active multi-level anti-corrosive pigment based on zinc orthophosphate hydrate. It possesses improved pigment structure, particle size distribution and dispersibility.

The increased water-soluble amount results in a better supply of inhibitive ions over a long time.
It shows excellent protective behavior in many binder systems, such as alkyd resins and physically drying systems, due to its special organic modification fixed on the particle surface.
It also provides adhesion promoter function of the organic treatment between metal substrate and organic coating or between inorganic anticorrosive pigment and binder.
HEUCOPHOS® ZPO is designed for solvent-based coatings based on short- & medium oil alkyds, high solids alkyds, high solids- & 2K epoxies, epoxy esters, silicone resins, and high solids polyurethanes (with low or no VOC).
It is also used in water-based coatings based on alkyd emulsions, 2K epoxies & polyurethanes (with low or no VOC), 1K polyurethanes, silicone resins, acrylic & modified acrylics, and butadiens.
It exhibits a higher performance efficiency in comparison to conventional zinc phosphates.
It is suitable for wash- & shop primers, direct to metal (DTM) coatings, powder coatings and UV cured systems.
