COATING COMPOSITIONS, COATED SUBSTRATES AND HERMETIC SEALS MADE THEREFROM HAVING IMPROVED LOW TEMPERATURE SEALING AND HOT TACK PROPERTIES

摘要

Novel coated substrates are disclosed wherein a substrate is coated with a coating composition that forms good hermetic seals at very low temperatures and exhibits good blocking and slip characteristics. Such coating composition is comprised of an aqueous dispersion of a substantially non-polar copolymer of ethylene and an alpha-olefin having less than 20 carbon atoms, and an additive selected from the group consisting of an anti-blocking and slip agent, a coalescent and wetting agent, and mixtures thereof.
