At ABRAFATI 2013 in São Paulo, the WACKER Group is showcasing two new vinyl acetate- and ethylene-based dispersions as binders for sophisticated adhesive solutions. VINNAPAS® EP6300 and VINNAPAS® EP7000 enable the formulation of high-performance, waterbased adhesives with a broad variety of uses, from bonding paper labels to plastic bottles over vinyl lamination to construction and flooring applications. Moreover, both products are manufactured without the use of alkylphenol ethoxylates (APEOs). Additional highlights are WACKER’s alpha-silane-based hybrid polymers for solvent- and tin-free sealants and adhesives and vapor- permeable liquid waterproofing membranes, dispersions for high-quality decorative paints as well as its dispersible polymer powders for decorative exterior plasters and self-leveling flooring compounds. ABRAFATI 2013 is being held from September 16 to 18 in São Paulo, Brazil.
At ABRAFATI 2013, WACKER is showcasing the newly developed VINNAPAS® EP6300 and VINNAPAS® EP7000 for the first time on the American market. The polymer dispersions based on vinyl acetate- ethylene copolymers (VAE) are ideal binders for formulating high-performance yet environmentally compatible water-based adhesives.
The new VINNAPAS® EP6300 is a VAE dispersion with an additional carboxyl functionality and a high solids content. The product features very rapid setting speed, high wet tack, good machinability, clear film formation and excellent mechanical properties. With its low glass transition temperature (Tg) of -3 to 3°C, VINNAPAS® EP6300 is well suited for bonding plastic films with surfaces which are porous or contain cellulose. Owing to its carboxyl functionality, the dispersion also exhibits outstanding adhesive properties on metal surfaces and aluminum foils.
At 71 percent, the solids content of newly developed VINNAPAS® EP7000 is the highest in the WACKER portfolio for VAE-based adhesives. The product delivers high adhesion, good water resistance combined with a rapid setting speed, and excellent wet tack. VINNAPAS® EP7000 is therefore suitable for a broad variety of uses, ranging from conventional paper and packaging through to construction and flooring applications.
Both products show good compatibility with plasticizers. Consequently, they are particularly suitable for adhesive formulations with a high solids concentration but moderate viscosity. They are also compatible with other latex dispersions, epoxy resins and water-based urethane dispersions. Moreover, both VINNAPAS® EP6300 and VINNAPAS® EP7000 are manufactured without using alkylphenol ethoxylates (APEOs), thereby enabling the formulation of environmentally friendly adhesives. Uses include bonding paper labels to plastic bottles, vinyl lamination, and construction and flooring applications.
