A reversible archival paper laminating adhesive (EVA). It is a water soluble, non plasticized, pH 7.5 ethylene-vinyl acetate copolymer emulsion which is ideal for laminating paper, boards, box making, envelope and general bookbinding applications.
It has passed the Silver Tarnish Test and PAT test and is less susceptible to acid hydrolysis than the more common PVA adhesives, which can break down and emit acetic acid vapours. These vapours can be particularly harmful to boxed items trapped in a microclimate.
