Pigmentpasta

摘要

Pigment paste for tinting a coating composition, the pigment paste comprising at least one branched alkyd having a viscosity below5 Pa.s, preferably below 3.5 Pa.s, at 23 DEG C at a shear rate of 100s<-1>, pigments, and 2 - 25% of an aromate-free solvent. The number average molecular weight Mn of the alkyd is between 2,000 and 2,400 g/mole. The degree of branching of the alkyd is at least 0.35 and preferably below 0.42. The oil length is between 76 and 84. The VOC is below 250 g/l.
