PU color paste has excellent quality stability and dispersibility. At the same time, it has the excellent quality of heat resistance, light resistance, migration resistance, color separation resistance, easy out resistance, acid and alkali resistance, strong tinting strength and high solid content.
Read More1. Adjust the polarity of the particle surface The reasons for the thickening and expansion of the storage stability of PU color paste are mainly due to the poor matching or compatibility between the polarity of the particle surface of the pigment and the polarity of the dispersion medium
Read MorePre-dispersed pigments are pigments that disperse traditional pigments to improve their particle size, coloring strength, and especially dispersibility. For the coloring of polyurethane resins, pigment predispersions (pastes) are often used instead of pigment powders; Because in the production of pr......
