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. It is also a gelling aid for organically modified bentonite. This product is a 50% solution of an electroneutral salt of a polycarboxylic acid with amine derivatives dissolved in higher aromatics. EFKA FA 4663 is an almost universally applicable additive for nonaqueous 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
