Origins of PVA Glue
PVA was discovered by German chemist Dr. Fritz Klatte in 1912. Its application to glues surfaced in the 1950s, when Georgia Institute of Technology chemist Ashworth Stull founded American Resinous Chemical Corp integrated the plasticization of polyvinyl acetate, which led to the birth of the “white glue”. He then sold the product to Borden Inc., and in the mid-1950s the product became known as “Elmer’s Glue-All”.
Properties of PVA Glue
Compared to other adhesives available in the market, wood glue is the easiest to work with. It became a favorite among craftsmen in the 1950s when rabbit glue was often the only available material – it was inconvenient as one needed to heat it to be able to use is as an adhesive. Wood glue, on the other hand, can be worked on or upon as it is. Aside from being less expensive, PVA wood glue offers more safety to crafts enthusiasts and kids alike as it is non-flammable and does not emit any harmful fumes. It is also non-acidic making it ideal for use with spatulas, or if your equipment, is not available you can use your bare hands. The only time it can cause harm is when ingested, so it is best to be kept away from kids who are not familiar with its use.
Uses of PVA Glue
Porous materials, like cloth, paper, and wood, offer wood glue more advantageous uses since it depends on excellent air circulation to maximize its bonding effects. On lighter materials, PVA glue would be set easily, but if you are working with heavier ones then pressure needs to be set to make the glue adhere to bonding.
Wood Glue shares some basic properties with Yellow Glue, more commonly known as “Carpenter’s Glue”. Differences in color are slight in comparison, although yellow glue is tested to dry up faster than white glue. This tends exhibit in yellow glue’s having a shorter shelf life than white glue, although yellow glue proves to show more resistance to moisture than its counterpart.
How to take care of your PVA Glue
PVA Wood glue is not waterproof, although it can be resistant, as long as you take proper caution in its storage. Room temperature would always serve best, but never let it freeze, as it would break down the polymers and affect the glue’s adhesive capabilities.

Music enthusiasts who use vinyl also claim that spreading glue on records and peeling it off removes particles that help restore audio quality before dust had set in. Some delicatessens also use glue to protect their cheeses from fungi and humidity.
