[Book Restorations] Evasol is a brand name for an aqueous adhesive Emulsion containing an Ethylene vinyl acetate copolymer. It is manufactured for conservation use to release less Acetic acid than similar adhesives by containing less Polyvinyl acetate and more long-chain Polyethylene in its copolymer formulation. The current formulation contains no plasticizers.
The adhesive is not classified as hazardous. The residual monomer is considered toxic. Use in a well-ventilated area.
Evasol SDS 
Evasol has passed the Photographic Activity Test. The adhesive has an initial pH of 6.5 to 7, but will drop slightly over time.

Physical and Chemical Properties
- Emulsion has 58 – 60% solids
- Viscosity = 2000 – 3000 cps
- Emulsion pH = 6.5 – 7
- Dry film will reconstitute to an emulsion form in contact with water.
Evasol may be applied with a brush or roller. It may be diluted with water or mixed with other adhesives such as Starch or Methyl cellulose by 10-15% before losing tack. The adhesive has a shelf life of up to 3 years, and requires occasional stirring. It should not be refrigerated, to avoid coagulation.
Forms and Sizes
500 mL, 1 liter, 5 liter, and 20 liter containers
