Q:

What are some uses for PVA glue?

A:

Polyvinyl acetates, or PVA glues, are the substance used to make standard glues and adhesives. They can be used on dry, porous surfaces to bond objects together.

PVA glues have the molecular formula (C4H6O2)n and are synthetic polymers that were discovered in 1912. PVA glues are known by many different names, and can be yellow or white. No matter the color or application, PVA glues need pressure to solidify and properly bond. If a PVA glue freezes, it becomes useless because the polymers break down and no longer function. These glues are toxic only if ingested and can be removed from the skin with soap and hot water.
