  • COATING FORMULATION FOR THE INTERIOR SURFACES OF CANS
    Publication number: 20140023782
    Abstract: The invention relates to a water-based can inner coating comprising a copolymer or a copolymer mixture of at least one aliphatic and acyclic alkene with at least one ?,?-unsaturated carboxylic acid in water-dispersed form, wherein the acid number of the copolymer or of the copolymer mixture is at least 20 mg KOH/g, but not more than 200 mg KOH/g, and at least one water-dispersed or water-soluble curing agent. Inventive can inner coatings are characterized in that due to the good crosslinking of the copolymer or of the copolymer mixture with the curing agent, the cured film on the inner surfaces of metal cans possesses excellent properties in regard to hardness, abrasion resistance and resistance towards hot liquids.

  • Flexographic printing forms having resistance to UV-hardenable printing inks
    Patent number: 5972565
    Abstract: A photopolymerizable mixture for photopolymerizable printing plates with an improved resistance to UV-hardenable printing inks, contains 10-45% by weight of at least one thermoplastic, elastomeric, block copolymer comprising of two or more polymer blocks comprising aromatic vinyl units and one or more polymer blocks comprising isoprene and/or isoprene/butadiene units. The block copolymer has a vinyl bond content not above 70%, a glass transition temperature not above 20.degree. C., and a peak temperature of a primary dispersion of tan .delta. not above 30.degree. C.
