Rheology is the study of the flow of matter, primarily in a fluid (liquid or gas) state, but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. Rheology is a branch of physics, and it is the science that deals with the deformation and flow of materials, both solids and liquids. The term rheology was coined by Eugene C. Bingham, a professor at Lafayette College, in 1920, … Webreflected in the flow point (Table 2). Wall paint 1 (blue curve) shows higher values for G′ and G″ as well as a higher flow point. This means that more force has to be expended to make this sample flow than for wall paint 2. In addition, it can be seen that wall paint 2 undergoes a much stronger structure collapse than wall paint 1, which is
