What is viscosity modifying agent?

A viscosity modifying agent (VMA) is a substance added to fluids to alter their viscosity, which is the measure of a fluid's resistance to flow. VMAs can enhance the stability and performance of materials, such as concrete or paints, by improving workability and reducing segregation. They are commonly used in various industries, including construction, food, and pharmaceuticals, to achieve desired fluid characteristics and ensure consistent product quality.
