USE OF AQUEOUS DISPERSIONS AS HOT-MELT ADHESIVE |
摘要 |
Use of an aqueous dispersion containing from 5 to 80 % by weight of a copolymer A) having a glass transition temperature of from 50 to 150 DEG C, and from 95 to 20 % by weight of a copolymer B) having a glass transition temperature of from -50 to +50 DEG C, in which the glass transition temperatures of the two copolymers differ by at least 20 DEG C, and at least one of the two copolymers has a content of an ethylenically unsaturated C3-C5-mono- or dicarboxylic acid, or the anhydride thereof, of from 3 to 70 % by weight, based on the particular copolymer, and the weight data of the copolymers A) and B) relate to the sum of A) and B), as a heat-sealable coating. |
