DuPont Elvax® 40W Ethylene-Vinyl Acetate Copolymer Resin

Elvax® 40W has a higher vinyl acetate content compared with the other Elvax® resins resulting in higher elongation, reduced hardness, improved solubility and adhesion, and significant differences in compatibility. To minimize viscosity changes in hot melt blends during processing, Elvax® 40W also contains butylated hydroxytoluene(BHT). Elvax®40W is supplied in pellet form and to prevent the pellets from blocking, low levels of an amide wax have been added to the polymer.Typical Applications: Laminating adhesives for a variety of substrates including plastics and films. This grade provides the extended open time often needed in industrial assemblyLacquers for wood, metal, metal foils, paper, and filmsFabric and decal coatingsHeat-seal coatings for backing card stock used in blister packagingWood primers and sealers. Combinations of Elvax® 40W and nitrocellulose form the basis for wood sealers offering toughness and good intercoat adhesion      Elvax® 40W is also suggested for use as a modifier in: Elastomer-based hot melt and hot melt pressure-sensitive adhesion formulationsNatural and synthetic elastomers to improve resistance to ozone crackingCaulks and sealants, including those based on asphaltAsphalt road repairing compositions for resurfacing, patching, and crack sealing to improve low temperature flexibility, strength properties, and adhesionTraffic paint formulationsSolvent-based and wax-based inksInformation provided by DuPont.
