In both cases we recommend pre-dispersing the pigments in a suitable solvent. With pastes, a weight ratio of 1:1 (paste : solvent) is recommended and, with powders, a weight ratio of approx. 1:2 (powder : solvent). In addition, it should be noted that aluminium pastes / aluminium powders have a limited shelf life. If the product is well past the expiry date, or if the drum has been stored incorrectly, this may lead to agglomeration, which causes the poor dispersion properties.
