Vinyl acetate ethylene copolymer dispersions are synthesized via emulsion polymerization from the monomers vinyl acetate and ethylene. These polymers are formed in the presence of water and the product is a milk-like latex emulsions. Vinyl acetate is a hard monomer that when polymerized forms poly (vinyl acetate) and is widely used in adhesive applications. The incorporation of ethylene as a comonomer effectively lowers the glass transition temperature of the final VAE copolymer without the incorporation of plasticizers which can migrate. The ethylene comonomer reduces water sensitivity (hydrophobicity) and enhances flexibility, toughness, adhesion and durability. VAE dispersions provide environmental advantages, since they exhibit good film-forming properties without coalescing agents, for example in low VOC paint and coatings.
VAE dispersions can be spray dried into powders. These VAE polymer powders are redispersible in water and the properties are unchanged.
Rovene 7005 is a non-plasticized vinyl acetate-ethylene copolymer with high solid contents developed to provide a versatile base for construction application. Rovene 7005 is a general-purpose copolymer emulsion that can be used in adhesive applications but especially for the improvement of all kinds of mineral bound building materials.
Rovene 7008 forms a tough but still flexible film with the best adhesive properties for broad applications. The Rovene 7008 exhibits excellent mechanical stability, and shows good wet tack and fast setting speed, so it can be ideally applied by a variety of techniques, including roller blade, spray gun, or extrusion. It shows good resistance against aging, light or alkali.
Tylac 7505 is a vinyl-acetate ethylene (VAE) copolymer powder that is readily dispersible in water and forms a stable emulsion. This flexible redispersible powder is especially recommended for blending with inorganic binders such as cement, gypsum, and hydrated lime, or as a sole binder for the manufacture of construction adhesives.
Tylac 7507 is vinyl-acetate ethylene copolymer powder that is readily dispersible in water and forms a stable emulsion. This redispersible powder is especially recommended for blending with inorganic binders such as cement, gypsum, and hydrated lime, or as a sole binder for the manufacture of construction adhesives.
Tylac 7501 is a redispersible VAE powder recommended for blending with inorganic binders such as cement, gypsum, and hydrated lime, or as a sole binder for the manufacture of construction adhesives.
