ADDITOL® XW 390
ADDITOL® XW 390 serves as a silicone-free flow and wetting agent designed for waterborne coating systems. It effectively prevents flow defects in various waterborne coatings and enhances substrate wetting. This APEO-free, formaldehyde-free, and tin-free formulation is compatible with epoxies (EP). Noteworthy features include improved edge coverage, long wave reduction, wet-on-wet properties, short wave reduction, and low migration. Widely applicable, it finds use in enamel, waterborne coating, and epoxy coating applications.

- Storage and Handling
At temperatures up to 25 °C storage stability packed in original containers amounts to at least 365 days. The color of Additol XW 390 can become somewhat darker on storage. The color change of Additol XW 390 on storage does not influence the results.
- 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.
- 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.
