STANDART® PCA Standard non-leafing aluminium pigments for powder coatings
As an alternative to the inorganic pigment coating of the PCR series, the pigments of the PCA series are encapsulated with organic polymer layers. In some cases it has been noticed that they offer slight benefits regarding the resistance properties compared with the PCR pigment grades.
The substantial advantages of PCA aluminium pigments are:
- good pigment wetting
- distinct non-leafing properties
- good rub resistance in single layer powder coating applications
- good electrical charging
- easy processing with Corona and Tribo techniques
- good shear stability – therefore very suitable for processing with the bonding technique
The typical pigment level of PCA aluminium pigments varies between 0.5% - 5.0%.
