TAFIGEL® PUR 64

TAFIGEL® PUR 64 by Munzing is a non-ionic polyurethane in butyltriglycol/water. Acts as rheology modifier. It provides strong pseudoplastic rheological profile with excellent shear thinning characteristics. The performance effect of this polyurethane thickener can be affected by other components of the formulation. Type and quantity of binder, co-solvents, coalescing agents, surfactants, wetting agents, pigments and flattening agents are the main partners to form a network. It is specifically developed to thicken polymer dispersions which are difficult to thicken and to minimize effects of other formulation components. TAFIGEL® PUR 64 builds up and stabilizes viscosity by forming a network between polyurethane and binder molecules. It can be used over a wide pH range. Has levelling and good flow. Used in aqueous systems and joint fillers. TAFIGEL® PUR 64 normal dosage ranges from 0.3 - 2% based upon total formulation.
