Product description: VINNAPAS® EP7000 is a poly(vinyl alcohol) stabilized vinyl acetate-ethylene (VAE) copolymer dispersion with a glass transition temperature (Tg) of approximately - 3 °C. It was developed as a high performance, ultrahigh solids dispersion offering superior adhesion, wet tack and setting speed over conventional VAE dispersions. Properties: VINNAPAS® EP7000 is manufactured to an ultra-high solids content of 70 percent while maintaining a viscosity range of 1200-2700 mPa.s. This combinationof high solids and moderate viscosity allows formulators to prepare very unique high solids products. This dispersion provides excellent wet tack, speed of set, machining characteristics, film clarity and adhesion. The dry film of VINNAPAS® EP7000 is tackier, clearer and more water resistant than standard grade VAE dispersions. VINNAPAS® EP7000 does not thicken excessively onthe addition of plasticizers, fillers or dispersible powders. Despite its high solids content, it can be applied on high-speed packaging machines using roll, extrusion or spray application equipment. VINNAPAS® EP7000 is produced without the use of any surfactants or defoamers that contain alkylphenol ethoxylates (APEOs). No formaldehyde or formaldehyde donors are intentionally added. Application: VINNAPAS® EP7000 can be used in numerous applications. For high-performance vinyl laminations, the product provides excellent adhesion, heat resistance and aesthetics with less warpage and reduced grain raise in wood-based substrates than standard solids dispersions. In clear film overprint laminations, VINNAPAS® EP7000 dispersion yields excellent film clarity and water resistance. For construction applications, VINNAPAS® EP7000 provides the high filler acceptance needed to produce high-solids adhesives. VINNAPAS® EP7000 can also be used in bottle labeling, bookbinding, and high speed packaging applications where its rheology and very fast setting speeds and extremely high wet tack offer unique performance characteristics.
