Methods for controlling viscosity during the formulation of fine chemical products
Thread Content
Many fine chemical products are formulated combinations, including various types of cleaners, personal care products, coatings, pesticides, etc. May I ask about the methods for controlling viscosity during this formulation process? A common approach is to add viscosity regulators, but is there a pattern to the effect of adding viscosity regulators on the overall viscosity of the product? Can it be approximated by using a linear relationship for estimation?
I’m not very familiar with other industries. In the coating industry, active monomers or diluents are added to adjust the viscosity, and their inclusion inevitably affects the viscosity of the entire product. The impact of active monomers on the product varies depending on their functional groups; generally, we can only determine their effect curves through literature and experimental testing, rather than by relying on linear relationships! The basic processes in the entire fine chemical industry are similar, but it is necessary to analyze each case on its own; a tailored approach is required before taking action. It’s just my personal opinion; I hope it can help you!
