Introduction
Vinyl acetate-ethylene copolymer emulsion (VAE Emulsion) is a copolymer of vinyl acetate and ethylene. It has been developed as a powerful base adhesive, offering the following unique characteristics: strong initial adhesion, high wet tack, good creep resistance, water/alkali-resistance, improved thickening response, and safe operation.
