Polyvinyl Acetate Emulsion

BRIEF OVERVIEW

Polyvinyl acetate emulsion is a thermoplastic polymer. Because of its excellent adhesion and convenience, it is widely used as adhesive for paper and woodwork. It is even used as a household adhesive/glue after re-packaged into smaller containers.

MANUFACTURING PROCESS

Polyvinyl acetate emulsion polyvinyl acetate latex emulsion made of vinyl acetate emulsion polymerization recipes plus complete information on single formula to observe the reaction solution temperature, such as high (at 85  above) can be appropriate additional 440 grams of ammonium persulfate, since the liquid temperature to rise to 90-95 , heat for 30 minutes, cooled to below 50. Observed after passing the emulsion appearance, dibutyl phthalate added vinegar, stir for 1 hour, and becomes Polyvinyl Acetate.
 

APPLICATION
    
As a dispersion in water, PVAc preparations are used as adhesives for porous materials, particularly for wood, paper, and cloth, and as a consolidant for porous building stone, in particular sandstone.
