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.
