What is the freeze-thaw stability of emulsion

Since the emulsion system is mainly composed of monomers, water, emulsifiers and water-soluble initiators and other basic components, half of which is composed of water, emulsions and coatings formulated with them are exposed to freezing conditions in many cases When the polymer emulsion encounters low temperature conditions, it will freeze. Freezing and thawing will affect the stability of the emulsion, ranging from an increase in the apparent viscosity of the emulsion to agglomeration of the emulsion. Freeze-thaw stability refers to the stability of the emulsion when it undergoes alternate freezing and thawing changes.
