AQUEOUS BINDERS FOR HEAT-SEALING APPLICATIONS |
| 摘要 |
The present invention relates to aqueous binders and to heat-sealing lacquers produced therefrom for heat-sealable coatings which adhere on aluminium without use of any primer, permit good sealability of the coated aluminium foil with respect to PS and/or PVC, and moreover feature good blocking resistance even at temperatures above 40° C. |

1. A process, comprising applying a heat-sealing lacquer
in a single layer to an aluminum surface prior to performing a sealing process, wherein the heat-sealing lacquer comprises at least 50% by weight of an aqueous dispersion comprising: a first polymer phase having a glass transition temperature of from −20 to 30° C.; and a second polymer phase having a glass transition temperature of from 20 to less than 50° C., and comprising from 2 to 10% by weight of at least one acid copolymerizable with methacrylates, based on a total weight of the first polymer phase and the second polymer phase. |
