Polyvinyl acetate (PVA or PVAc) is a rubbery synthetic polymer with the formula
Applications and uses
As an emulsion in water, PVAc emulsions are the adhesives for porous materials, particularly for wood, paper, and cloth, and as a consolidant for porous building stone, in particular sandstone.
as wood glue PVAc is known as "white glue" and the yellow "carpenter's glue" or PVA glue.
in paper converting as fast binding adhesive
in bookbinding and book arts due to its flexible strong bond and non-acidic nature (unlike many other polymers).
for handcrafted works.
To a lesser extent PVAc emulsion are used in paper coatings, paint and other industrial coatings.
