Description
[Reichold Chemicals Inc.] A brand name for a series of ethylene/vinyl acetate copolymer aqueous emulsions. Elvace emulsions were formerly produced by DuPont with different number designations and are distributed as Vinamul emulsions in Great Britain. The milky white Elvace emulsions are typically used as adhesives. They dry to a clear film, have very good aging properties and are resistant to UV degradation. The shelf life of the emulsion is about 6 months.
- Elvace 40-704 (formerly 1874) - 55% solids, 3500-4500 cps, pH 4.5-5.5, particle size = 0.2-1.0 micrometers.
- Elvace 40-705 - 54.5% solids.
- Elvace 40-709 - 56% solids.
- Elvace 40-724 - 57.5% solids.
