Properties: VINNAPAS® EP6300 is a unique dispersion combining high solids with carboxyl functionality. The carboxylation provides crosslinking sites and causes the dispersion to thicken in the presence of alkalies. This dispersion exhibits high wet tack and excellent mechanical stability. It has lower plasticizer and solvent thickening response than conventional poly(vinyl alcohol) stabilized dispersions. The dried film exhibits excellent flexibility. The film exhibits slight dry tack, is heat sealable, and can be dissolved with water at a pH of approximately 9.5. VINNAPAS® EP6300 does not use any surfactants or defoamers that contain alkylphenol ethoxylates (APEOs).

Application: VINNAPAS® EP6300 is an excellent base for adhesive formulators and can be used in a wide variety of applications. The ethylene in the polymer acts as an internal plasticizer which provides flexibility and reduces or eliminates the need for plasticizer in many applications. The carboxylation provides increased adhesion to metal surfaces such as aluminum, mild and galvanized steel, brass, lead, and tin plate. It also provides improved adhesion to metallized films and other films such as Mylar, cellulose acetate, PVC, and cloth. The films can be coated, dried, and heat sealed to a variety of surfaces. VINNAPAS® EP6300 can be used in heat seal applications for metals foils and for plastic adherends.
