Acrylic leveling agents include pure acrylic leveling agents and modified acrylic leveling agents.

Pure acrylic leveling agents include traditional non-reactive acrylic leveling agents and new functional acrylic reactive leveling agents. This is a type of acrylic homopolymer or copolymer with different molecular weights. These leveling agents only slightly reduce the surface tension of the coating, can balance the difference in surface tension of the paint film, and obtain a truly flat, mirror-like paint film surface. If the molecular weight is high enough, such leveling agents also have the functions of degassing and defoaming. The disadvantage of traditional non-reactive acrylic leveling agents is that high molecular weight products may produce haze in the paint film, and low molecular weight products may reduce the surface hardness of the paint film. Acrylic leveling agents containing reactive functional groups can well resolve this contradiction, while providing good leveling properties, it will not produce haze and reduce surface hardness, and sometimes it will also improve surface hardness.
