- Special Properties
Additol XW 390 prevents flow defects in all waterborne coating systems and promotes substrate wetting. There is no effect on the recoat adhesion.
- Distinguishing Features
Additol XW 390 suppresses more effectively the tendency to cratering in paint films than Additol XW 395 does and particularly at very low film thicknesses.
Applications & Uses

- Use Level
- 0.1 – 1.0 % binder
- Suggested Uses
Additol XW 390 can be applied in all commonly used air-drying and stoving, waterborne coatings systems, especially in alkyd/melamine stoving coatings, air-drying alkyd resin coatings, phenolic resin coatings and epoxy resin coatings.
Application-related film defects, in the case of roller, spray and dip-coating, such as craters, poor flow and variable wetting of the substrate due to dirt are effectively prevented with Additol XW 390. In most cases, with the addition of Additol XW 390, there is no problem in rewetting the coating film.
- Processing Information
Additol XW 390 can be added in any stage of coatings manufacture but preferably however in the pigment dispersion. The effectiveness of Additol XW 390 is already strongly shown at levels between 0.1 - 1.0 % based on binder. In special cases, however, a higher dosage may be required. The most favorable amount should always be determined by preliminary trials.
