Jade 403 is considered the gold standard of all the PVA glues. It has been tested at the highest levels in terms of its archival characteristics. It is pH neutral, acid free, dries and stays flexible, non yellowing, water soluble, and contains no solvents. It is the most recommended PVA glue by professional bookbinders. Image shows range of glues from 4 ounces to 32 ounces.
PVA Freeze Warning: The adhesive properties of PVA significantly diminish when it freezes. Therefore, during the winter months we try to monitor when we ship our PVA glues. If the weather is such that our glue shipments may be affected, we will hold your entire order until conditions allow us to ship. A tell-tale sign that your PVA was frozen is if the glue exhibits a chalky or cottage cheese like texture. If you can stir the glue and it smooths out, it should be fine. If not, it should be discarded. We suggest you do not order PVA glue during the winter months when you know the temperature may below freezing.
