Dynoadd F-1 is a polymeric, non-silicone general-purpose flow and anti-crater additive for solvent-borne coatings. It lowers surface tension in coating formulations. Dynoadd® F-1 has applications in industrial coatings, coil coatings, automotive OEM, printing inks, and woods coatings. The additive is compatible with most solvent-borne and non-solvent coating systems independently of lacquer chemistry. It may be used in all layers in multi-layered systems.
