- Special Properties and Uses
Additol XW 6544 was designed as defoamer for airless application especially for wb epoxy systems. It prevents foam formation and reduces pinholes in high film thickness due to optimized reflow properties. Because of the high efficiency and the very low VOC content (< 1 %), our Additol XW 6544 can also be used as defoamer for wb pigment concentrates and for low VOC decorative coatings.
- Processing Information
The defoamer is generally added undiluted directly to the grind mix. In some cases it may be an advantage to add 1/3 of the total quantity to the grind mix and 2/3 to the let down. The total recommended dosage is generally 0.5 ‐ 1.0 % on total formulation. In some cases, where especially strong foam generation is observed, a higher dosage may be necessary; it should, however, not exceed 1.5 %. The optimum dosage may vary from formulation to formulation. For airless application based on wb epoxy systems the use of a combination based on Additol VXW 6388 and XW 6536 as rheological modifier and Additol VXW 6394 as dispersing agent are recommended.
