Elvax 40W Ethylene-vinyl acetate copolymer DuPont Ethylene co-terpolymers - solid (EVA, EMA) >> Ethylene Vinyl Acetate, EVA Coatings >> Solventborne Soluble in organic solvents Elvax(R) is the DuPont registered trademark for a broad line of ethylene-vinyl acetate copolymer resins for use in adhesives, sealants, and coatings. Elvax(R) blended with a petroleum wax and resin tackifier is the basis of many hot melt adhesives. In addition, Elvax(R) resins impart plastic-like properties that enable wax to compete effectively with high-quality polymeric coatings. In summary, Elvax(R) resins are key ingredients in a variety of hot melt and solvent-applied systems. They are used as: Resin bases for flexible, heat-sealable, hot melt coatings with excellent water vapor and gas barrier properties. High Vinyl Acetate Resins (>30% VA) offer excellent adhesion to nonporous surfaces, greater solubility in organic solvents than other Elvax(R) resins, and broad compatibility with tackifier resins. They are particularly useful in solvent-applied adhesives and coatings, and can also be incorporated in specialty hot melt blends. Elvax(R) 40W, because of its higher vinyl acetate content (40% VA), is more soluble in organic solvents and is compatible with a broader range of polar resins including nitrocellulose. All grades contain 190-910 ppm butylated hydroxy toluene. The "W" postscript denotes grades containing an anti-blocking additive. Ethylene-vinyl acetate copolymer resin. Contains butylated hydroxytoluene and an anti-blocking additive. Used as a resin base for flexible, heat-sealable, hot melt coatings. Provides very good water vapor and gas barrier properties, toughness, flexibility, very good adhesion to nonporous surfaces. Suits particularly for solvent-applied coatings. Possesses high vinyl acetate content. Offers compatibility with a broader range of polar resins including nitrocellulose.
