Anti-crater and flow additive for solvent borne coatings
• Excellent flow and levelling
• Improves substrate wetting
• Eliminates craters and pinholes
• FDA 21 § 175.300 compliant
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 makes it suitable as dispersing aid for carbon black pigments.
