Aqueous thickener is a rheology additive that not only thickens the paint and prevents sagging during construction, but also gives the paint excellent mechanical properties and storage stability

Aqueous thickeners are now the dominant associative polyurethane thickeners that confer better fluidity, excellent film forming, leveling, water resistance, and gloss

The associated structure of the associative polyurethane thickener is destroyed under the action of shear force, the viscosity is reduced, and when the shear force disappears, the viscosity can be restored, which can prevent the phenomenon

Polyurethane thickeners have both hydrophilic and hydrophobic groups on the molecule, and the hydrophobic groups have strong affinity with the substrate of the coating film, which can enhance the water resistance
