Suggested Uses
  • Additol VXW 6387 is usually compatible with waterborne, solvent based and solvent-free binders. It prevents the sedimentation of pigments in paints. The rheological character of paints is improved. The tendency to flow on vertical surfaces is reduced. The edges of substrates are better covered in case of dipping application.
  • The drying of oxidatively drying systems is not influenced by Additol VXW 6387, if the appropriated dose is used. Also the efficiency of siccatives in paints, stored for a long time, is not reduced using Additol VXW 6387.
  • Considering anti-corrosive paints, there is no corrosion-resistance loss by using Additol VXW 6387. It is recommended to be used for the activating of organophile bentonites and it improves the effect of pyrogene silica.
Processing Information

Additol VXW 6387 can be added in any stage of the paint production. We especially recommend the addition during pigment dispersion. Amounts up to approx. 5 % on pigments and fillers may serve as a guide. These are standard values, the most effective dose must be found by experiments.
