NUOSPERSE® AP 657

NUOSPERSE® AP 657 by Elementis is a PAHs-free, amphoteric wetting and dispersing agent for pigments which can be applied to practically all solvent-based paint systems. It contains very low aromatic solvent content with film forming backbone.

• It improves the dispersion of the titanium dioxide pigments, providing greater opacity and whiteness which indicates that for equal hiding, the amount of white pigment could be reduced in the vinyl compound and be replaced by less expensive fillers.
• It provides improved stability of the paint and better coloring & covering power of the paint.
• It can be applied to practically all paint systems, e.g. to air-drying alkyd paints, alkyd-melamine baking enamels, acrylic enamels and industrial primers.
• It will not influence the gloss and adhesion of the paint unfavourably.
• It can be used in pigment pastes which are to be added to vinyl film and sheeting, extrusions, plastisols, organosols and solution coatings & inks.
• Recommended dosage level is 0.5-2.5% calculated on the pigment paste and 2.0-5.0%, based on the weight of the dry pigment.
• It has a shelf life of 3 years.
