Q1: What types of pigments and fillers is ADDITOL VXW 6208/60 especially effective for?
A: ADDITOL VXW 6208/60 is particularly effective for dispersing hydrophobic organic pigments, carbon black, and inorganic fillers such as silica, calcium carbonate, and talc in solvent-borne and high-solids coating systems.
Q2: Can ADDITOL VXW 6208/60 be used in waterborne systems?
A: No — ADDITOL VXW 6208/60 is specifically formulated for solvent-borne and high-solids systems. It is not compatible with water-based dispersions or emulsions due to its non-ionic, solvent-soluble molecular structure.
Q3: How does ADDITOL VXW 6208/60 improve pigment wetting and dispersion stability?
A: It functions by reducing interfacial tension between the pigment surface and the resin/solvent medium, promoting rapid wetting and preventing agglomeration through steric stabilization. This leads to improved color development, gloss, and long-term storage stability.
Q4: What is the recommended addition sequence during formulation?
A: For optimal performance, ADDITOL VXW 6208/60 should be added to the millbase prior to pigment incorporation — either dissolved in part of the solvent or pre-mixed with the binder — to ensure immediate contact with pigment particles during dispersion.
Q5: Is ADDITOL VXW 6208/60 compatible with common crosslinkers used in industrial coatings?
A: Yes — it demonstrates good compatibility with melamine-formaldehyde, blocked isocyanate, and other conventional crosslinkers used in thermosetting solvent-borne systems, without interfering with cure kinetics or film formation.
