What is the minimum film formation temperature?

Coating products with water as a solvent should consider the minimum film formation temperature of the variety during construction, such as the minimum temperature required for polymer emulsion to form a transparent continuous film after Spreader.

Often expressed as MFT. Below this temperature, the emulsion Spreader layer is in a cloudy state and no longer films formation. MFT is related to the type, ratio and degree of plasticization of the main film formation substances of Coating, which determines the minimum construction temperature of Coating and the length of the construction period in one year.

Adding coalescing agent, plasticizer, water-soluble resin or changing the polymerization method to the emulsion can change the minimum film formation temperature of the emulsion.
