As a modern anti-settling agent, it acts via adsorption phenomena on the pigment surface and effectively prevents pigments from settling and forming hard, difficult-to-stir sediments even in low-viscosity coatings such as, e.g., dipping paints and wash-primers. This is possible even in the presence of specific high density pigments based on lead, chrome, barium, iron and titanium. In addition, the uniform electrostatic charge imparted by EFKA® FA 4600 prevents re-agglomeration thereby counteracting any premature settling of the pigments. EFKA® FA 4600 is an easy to use liquid anti-settling agent, the particular advantage of which is that it is effective over a broad range of polarity. It can, therefore, be used in a nitrocellulose lacquer, the solvents of which are mainly polar, as well as in decorative paints which only contain white spirit, i.e., a non-polar solvent. EFKA® FA 4600 is also an excellent anti-settling agent for low-viscosity printing inks, e.g., flexographic and gravure. In particular it counteracts the tendency of inorganic pigments to settle. 收起 | |

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 |
