PVA - Polyvinyl Acetate

This is in response to a question asked by an internet friend.

PVA is an abbreviation that stands for polyvinyl acetate. It is available in both archival and non-archival formulas in pints, quarts, or gallons. I personally prefer the Jade 403 PVA (polyvinyl acetate) adhesive for my handmade bookmaking and box-making projects. Jade is one of only three brands of polyvinyl acetate adhesive (PVA) which has been found to maintain a good pH level during natural aging tests, making it suitable for box-making and other book and paper uses. In box-making, for example, the important factor is that it has minimal detrimental out-gassing. Of the three, it also shows the least yellowing during the natural aging tests. Note: PVA must not be allowed to freeze, therefore it is shipped in insulated boxes to or from colder climates in winter.

PVA closely resembles Elmer's Glue in consistency and workability. Differences that I've personally noted is that PVA has less water content allowing it greater adhesive qualities. It is a clear drying artist's glue. One you are sure to immediately fall in love with.
