Medium Shear Polyurethane Thickener
Medium shear thickener with high thickening efficiency, good flow and leveling properties, excellent uniform film-forming properties, and gloss display performance. It is especially suitable for use as a synergistic thickener, widely used in the formulation of interior and exterior walls from flat to high gloss.
Description
YINYANG MEDIUM SHEAR POLYURETHANE THICKENER
There are three different types of associative thickeners used in waterborne polyurethanes:
1. Low shear rate thickeners: The surface of waterborne polyurethane thickened with these associative thickeners has a weak pseudoplastic rheological behavior to have high thickening effect.
2. High shear rate thickeners: The rheological curve of waterborne polyurethane thickened with this thickener is actually Newtonian. This thickener works in the high shear rate range, with good flow and good leveling effect.
3. Medium shear rate thickeners, balance of low shear and high shear thickener, keeps good low and good thickening effect.
Polyurethane thickeners exhibit very different rheological properties under low shear (low shear) and high shear (high shear) conditions. In low shear environments, thickeners provide stable viscosity, allowing the product to maintain a uniform texture and flow. In high shear environments, the viscosity of the thickener decreases, making the product easier to spread or spray while maintaining its stability and covering ability.
Effect of use under medium conditions
Medium shear thickener with high thickening efficiency, good flow and leveling properties, excellent uniform film-forming properties, and gloss display performance. It is especially suitable for use as a synergistic thickener, widely used in the formulation of interior and exterior walls from flat to high gloss.
YINYANG MEDIUM SHEAR POLYURETHANE THICKENER YT-8W, alternative of RM-8W, It not only has excellent thickening effect, but also has good leveling and fluidity. It is widely used in various water-based systems such as latex paints and adhesives.
YINYANG MEDIUM TO LOW SHEAR POLYURETHANE THICKENER HZ-052, better thickening effect than 8W, with lower dosage to get higher viscosity and keep good glow.
