Ultra-high performance non-leafing aluminum pigments for powder coatings
PCU (=Powder Coating Ultra-High Performance) is a new generation of non-leafing aluminum pigments with an extremely high level of chemical resistance.
The PCU aluminum pigments consists of a platelet core of high purity aluminum, which is embedded in an inorganic matrix of silicon dioxide using a sol-gel process and subsequently encapsulated with a special organic acrylate layer in a second pigment coating stage.
This unique inorganic-organic double provides the PCU aluminum pigments an exceptional resistance regarding corrosion and chemical resistance. Therefore, the PCU pigments open up a new application fields for metallic powder coatings where improved chemical resistance is required.
