Abstract: An aqueous barrier coat for formable cellulosic substrates comprises a blend of A) at least one aqueous polymer binder dispersion at 40 wt % to 95 wt %, B) at least one active filler at 3 wt % to 30 wt % and, C) one or more optional additives, such as wetting additives, dispersants, thickeners, defoamers, and crosslinkers. Crystallinity is present in at least one of the polymer binder dispersion and active filler particle. The resulting dried film has a shear storage modulus between 50° C. and 60° C. in the range of 1.5×106 to 1×109 Pascals, a shear storage modulus between 80° C. and 90° C. in the range of 2×105 to 5×107 Pascals, and a shear storage modulus between 100° C. and 110° C. is in the range of 5×103 to 1×106 Pascals. The total weight % of crystalline polymer binder and the crystalline active filler combined is greater than 50%.

Abstract: A film forming aqueous dispersion having utility as heat seal coatings for blister packaging applications comprises a blend of 10-90% by weight of one or more polyurethane dispersions; 90-10% by weight one or more compatible ethylenic copolymer dispersions/emulsions; an anti-blocking additive at 0.1-12 weight % of the total solids; and optional additives including wetting, defoaming, thickener, antifungal additives. The heat seal coating compositions provide enhanced and balanced properties such as a reduction of organic solvents, a tack free coating surface off the press, good press runnability, easy clean-up, antiblocking from ambient temperature to 50° C., heat-activation with no pot life at elevated temperatures, and, heat sealability to various plastic substrates including Virgin Poly(ethylene terephthalate) (PET), recycle PET (RPET), Amorphous PET (APET), PET-Glycol modified (PETG), PETG/APET/PETG (GAG) and Polyvinyl chloride (PVC).

Abstract: A coating composition for creating a rough tactile surface on a substrate comprises a plurality of high aspect ratio flakes dispersed through a radiation-curable binder. The composition is can be employed in anilox and gravure printing systems incorporating doctor blades and like skimming units in which conventional tactile coatings cannot be successfully employed.
