EFKA® FA 4663 is a dispersant and grinding aid, anti-settling and anti-floating agent for coatings, paints, printing inks, and other similar surface coatings. Gelling aid for organically modified bentonite.

Applications

EFKA® FA 4663 is an almost universally applicable additive for non-aqueous coatings. It has proved its value in particular in systems based on alkyd resins, alkyd/melamine resins, acrylic and epoxy resins, chlorinated rubber, linseed oil/stand oil, etc. If some linear binders which contain hydroxyl groups (e.g. Desmophen® types from Bayer) are used with our product, thixotropy can occur.
