In coating technology, rheology modifiers are mainly used to provide pseudoplastic or thixotropic properties. The rheological properties are determined by the composition and concentration of the ingredients in the coating formulation. The coating formulation consists of binders (polymers, oligomers, reactive diluents), solvents (organic, water), pigments (organic, inorganic), fillers and Auxiliary (stabilizer, initiator, catalyst, etc.). Therefore, there is no universal solution for all coatings, but there are many different technologies and products, which have more or less clear application limits. The most outstanding point is that from the production process to the transportation, storage, and final (industrial) application process, the rheological characteristics of coating formulations in their service life may vary widely. All existing rheology modifiers can be classified as inorganic And organic chemicals.
