General architectural coating manufacturers should carry out the following routine performance inspections for the purchased emulsion. (1) General visual inspection of appearance. Observe the hue of the emulsion and whether there are particles and impurities. (2) Viscosity Since polymer emulsions a... read more
The lowest temperature at which a polymer emulsion can form a continuous transparent film is called the lowest film-forming temperature, usually expressed by MFT. The lowest film-forming temperature of emulsion is an important application index of emulsion. That is, below a certain temperature, aft... read more
Glass transition temperature T. (Also known as the second transition temperature) refers to the temperature at which a polymer changes from an elastic state to a glass state, and is an important performance index of a polymer. The polymer exhibits elasticity above this temperature, and the polymer e... read more
1) Vinyl acetate copolymer emulsion Although vinyl acetate emulsion can be used to formulate interior wall coatings, it is basically not used in architectural coatings due to some inherent defects. However, vinyl acetate can be copolymerized with many other monomers to make various emulsions, many ... read more
Due to the different indoor and outdoor environments, there are great differences, and there are also different requirements for paint emulsions. In general, emulsions for exterior wall coatings have higher performance requirements than those for interior wall coatings, because exterior wall coatin... read more
