High Shear Polyurethane Thickener
Under high shear conditions, the viscosity of polyurethane thickeners decreases, making the product easier to process and apply. This property gives the thickener better leveling and covering ability in a high shear environment, thereby improving the quality and appearance of the product. Thickeners under this condition are suitable for products that require high fluidity for easy processing and application, such as cosmetics, paints, etc.
Description
YINYANG HIGH 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 high shear conditions
Under high shear conditions, the viscosity of polyurethane thickeners decreases, making the product easier to process and apply. This property gives the thickener better leveling and covering ability in a high shear environment, thereby improving the quality and appearance of the product. Thickeners under this condition are suitable for products that require high fluidity for easy processing and application, such as cosmetics, paints, etc.
