Dynoadd F-3B is a low-migratable version of Dynoadd F-3. It is a flow and anti-crater additive for solvent-borne coatings for food contact applications. It lowers surface tension, thus improves substrate wetting. Surface defects like craters, cissing and pinholes are eliminated. Dynoadd F-3B has limited, but balanced compatibility with most backbone resins, and has defoaming properties. Dynoadd F-3B is an excellent choice in multiple-layer coatings, as it does not influence inter-coat adhesion. Dynoadd F-3B’s good wetting properties make it suitable as dispersing aid for carbon black pigments.
