Coapur™ 3025

Coapur™ 3025 by Coatex (Arkema Group) is a non-ionic, water soluble polyurethane. It is an associative and solvent-free rheology modifier. Provides a pure Newtonian rheology to water-borne systems and improved gloss level. It allows to adjust selectively high shear viscosities and thus ensures excellent film build, spatter resistance and leveling together with low dosage and flexibility of use. It can be used in combination with low shear effective thickeners (THIXOL™ 53 L, RHEOTECH™ 2800, COAPUR™ 6050) in flat, sheen and semi-gloss dispersion paints or as a sole product in gloss dispersion or water-soluble alkyd paints. Produces very good results with COAPUR™ 3025/ THIXOL™ 53 L combinations, e.g. in VOC-free, high leveling and one-coat flat dispersion paints or in water-based woodstain formulations. Recommended dosage level is 0.5-1.5% depending on the rheological profile of the co-thickener, when used in combination, or between 1-3% when used as a sole thickener. Coapur™ 3025 has a shelf life of 12 months.
