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. 收起 |
