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.
Used for waterborne industrial paint, waterborne ink, waterborne interior and exterior wall paint and so on. Excellent brush feel, anti-roll coating excellent flow, leveling performance and hiding effect.
It is used for water-based synthetic leather, water-based paint, water-based adhesive and other fields. The composite use with cellulose ether and polyacrylic acid thickener can give the coating better leveling property and anti-splash property. It is resistant to microbial degradation, and its thickening ability depends on the structure of the emulsion, particle size and emulsifier, as well as film forming additives and surfactants in the coating
