Airflex 465 vinyl acetate-ethylene copolymer Air Products Ethylene copolymers - emulsions (VAE, EVC) >> Vinyl Acetate Ethylene copolymers, VAE Airflex 465 emulsion is a unique, rapid-setting vinyl acetate-ethylene copolymer. It is not simply a high-solids version of Airflex 400 emulsion, but a polymer that has outstanding adhesion to very difficult-to-bond substrates including polyester, poly(ethylene terephthalate), tempered aluminum foil and polystyrene. The emulsion combines very high-solids content with a low viscosity — a combination that permits the addition of very highfiller loadings, resulting in adhesive formulations with solid contents as high as 80 percent, or even greater. The emulsion will not thicken excessively on the addition of plasticizers that also allows for the formulating of very high-solids adhesives. Airflex 465 emulsion is very shear stable, which means that it can be applied on high-speed packaging machines using roll, extrusion or spray equipment. The emulsion dries to a slightly tacky, clear, water-resistant film. Compounding Airflex 465 emulsion can be compounded in a manner similar to Airflex 400 emulsion and accepts all the common plasticizers, solvents, tackifiers and fillers used with vinyl acetateethylene emulsions. The emulsion accepts extraordinary amounts of fillers, such as clay and calcium carbonate, without excessive thickening. It also does not thicken rapidly on the addition of plasticizers and solvents, which is a useful property where high solids at moderate viscosities are required. It is compatible with other vinyl acetate-based polymers, including Vinac® homopolymer, Flexbond® copolymer and Airflex copolymer emulsions. Airflex 465 emulsion can also be blended with Flexbond acrylic lattices. Applications: Airflex 465 emulsion’s high-solids content and excellent adhesion to plastic substrates make it especially useful in bonding PVC film to particle board, where the low water content reduces swelling of the wood. The excellent adhesion to difficult-to-bond surfaces shown by the emulsion is very useful in laminating films such as polyester, poly(ethylene terephthalate), poly(vinylidene chloride) and polystyrene to coated or uncoated papers. It shows good adhesion to metallized films and tempered aluminum foil. The rapid setting speed of Airflex 465 emulsion makes it very useful in high-speed packaging applications. The high-solids content is also important in bookbinding. The clear film and excellent adhesion of the emulsion are important in film overlay laminating. Unique, low viscosity/high solids, rapid-setting vinyl acetate-ethylene copolymer emulsion. The emulsion dries to a slightly tacky, clear, water-resistant and flexible film. Provides adhesive formulations with solid contents as high as 80 percent. Adhesion to difficult-to-bond surfaces, metallized films and tempered aluminum foil.
