VAE Vinyl Acetate-Ethylene Copolymer Emulsion
Número CAS: 24937-78-8
VAE Vinyl Acetate-Ethylene Copolymer Emulsion is a high-solid (55–58%) aqueous dispersion of vinyl acetate-ethylene copolymer with Tg adjustable from -15 to +15°C through ethylene content. It serves as the primary binder for interior architectural paints, construction adhesives, and textile and paper finishing, delivering excellent adhesion to cementitious and porous substrates with inherently low VOC and zero plasticizer. The ethylene comonomer imparts permanent internal flexibility that does not migrate or volatilize over time.
