PHOSPHINAL PZ04 is a Zinc Aluminium phosphate developed to give higher and longer anticorrosion performance to the epoxy coatings than standard Zinc phosphate. It is a stable and non-hygroscopic white powder with a low tinting strength, it is easily dispersed.
PHOSPHINAL PZ04 is suitable for a wide range of solvent and water based resins. This pigment is specifically adapted to epoxy resins and acrylic systems.
