Original: How to use acrylic thickeners in coatings?

Acrylic thickeners include polyacrylate and acrylic acid copolymers (alkali swelling) two categories, acrylic lipid thickener thickening mechanism is that its microparticles can be adsorbed in the surface of latex particles in the coating, alkali swelling after the formation of an overmolding layer, increase the volume of latex particles, so that the movement of particles is assisted and lead to increased viscosity of the coating system: there is also a thickener swelling increase, increasing the viscosity

Acrylic thickeners can be used alone or in coordination with other thickeners in coating formulations, and at relatively low dosages, can effectively improve the viscosity

Its performance can be summarized into four points:

1. Improves fluidity and leveling
   
   

   (Small recommendation: adding a small amount of surfactant or glycol ether co-solvent to reduce the low shear viscosity can change the rheological properties of the thickener, and adding some pre-dispersed pigment pastes can also produce this effect
