Is elmers glue like pva?
ELMER’S GLUE ALL It has generally been thought that Elmer’s Glue All is a PVA emulsion. In its original formulation, it was a casein glue, but about 20 years ago, the Borden Co. changed the formula to a PVA emulsion. Recently, there has been an additional change. Now, unlike other PVA emulsions that are soluble only in PVA solvents after they are dried, the only solvent recommended by Borden, Inc. for Elmer’s Glue All is water. They claim that any other solvent would only set the glue more. Because of the uncertainties about Elmer’s Glue All, it is not recommended for conservation. It is, however, an excellent glue for wood that is not going to be exposed to outside environments and for consolidating quantities of faunal bone. The stock solution of Elmer’s Glue All works fine as glue, but it must be diluted with water in order to use it to impregnate and strengthen material. For dilution purposes, stock Elmer’s Glue All has approximately 0.9 grams of resin per one gram of stock mixture
