the present situation of using PVA glue

Polyvinyl acetate was first discovered by German chemist Fritz Klatte in 1912. Klatte converts acetic acid and acetylene into vinyl acetate monomers, but now acetic acid is added to ethylene and then a palladium catalyst is used.

This widespread use of glue has played a key role in the advancement of methods used in today's adhesives. PVA products are prepared using polyvinyl acetate emulsion, which can be modified in the form of sealants, paint base materials and coatings.

PVA is commonly used for binding wood but is also used in many situations that require flexible durability and substantial longevity.

Designed specifically for application on porous surfaces, PVA is a poor choice for things like metals, glass, or plastics as it will not easily bond with materials lacking texture. If the glue cannot infiltrate the material, it cannot properly adhere.

Bookbinding and leather production are big fans of PVA as the glue bonds readily to both leather and paper, and its compound resists breaking down pH levels in the paper resulting in a prolonged whiteness of page.

PVA bonds decently to cloth though is not intended for it, and the fact that it is a durable, non-toxic adhesive makes it extremely popular for many in home applications. Kids love it for all sorts of hobbies as it holds very well to paper, cardboard, popsicle sticks and the like.
