Polyurethane association thickener is a hydrophobic association water-soluble polymer mainly used to improve the rheological properties of various water-based systems. Its main characteristics are as follows: hydrophobic association: polyurethane association thickener is a polymer composed of hydrophobic chain segments and hydrophilic chain segments, and the association structure is formed between the hydrophobic chain segments through hydrophobic interaction, thereby increasing the viscosity and shear viscosity of the system.

Good thickening effect: polyurethane associated thickener can significantly improve the Viscosity and shear viscosity of the water-based system, thereby improving the fluidity, coating and leveling of the system.
