Features and advantages

German technical background VOK®- FL 3951 P is a high molecular weight copolymer containing pigment affinity groups, which can improve the dispersion (viscosity reduction) of solid particles and increase the addition of fillers and pigments. The leveling (DOI - freshness) of the powder coating with this additive can be improved, and better degassing and substrate wettability can be obtained.
