Wacker Vinnapas® 7220 E Vinyl Acetate-Ethylene Copolymer
Categories:	Polymer; Thermoplastic; Ethylene Vinyl Acetate
Material Notes:	Product description: VINNAPAS® 7220 E is a semi flexible dispersible polymer powder based on vinyl esters, ethylene and acrylic acid ester for very good workability and excellent tensile adhesion strength after water immersion. Properties: VINNAPAS® 7220 E is a polymer powder and is dispersible in water. VINNAPAS® 7220 E is ideal for modifying cementitious and gypsum-based mortars, e. g. tile adhesives. VINNAPAS® 7220 E contains a fine mineral filler as an antiblocking agent and is produced without the addition of organic solvents, plasticizers and film-forming agents. Special features: VINNAPAS® 7220 E has no effect on rheological properties and is a polymer powder in the medium Tg range. It is suitable for formulating high-quality, low emissions flexible tile adhesive that feature excellent tensile adhesion strength, especially after immersion in water and exposure to freeze/thaw cycles.
