Low-viscosity paint has the advantages of easy dispersion of powder during production and high production efficiency.Highly thixotropic coatings have excellent thick coating properties,which can greatly improve construction efficiency.However,there is an interaction between viscosity and thixotropy,which makes it difficult to establish a low-viscosity and high-thixotropy system.In this paper,experiments were carried out on the combination and addition of thixotropic agents and the application of rheological additives,and successfully established a low-viscosity and high-thixotropic coating system.
