  • Patent number: 6451141
    Abstract: The invention relates to a method of producing seals and coatings, and of bonding tiles and floor coverings, in which aqueous dispersions containing at least 20% by weight of filler and comprising a polymer mixture of a) an acrylate polymer A having a K value of from 5 to 55 and a glass transition temperature of below −10° C. and b) an acrylate copolymer having a glass transition temperature of from −50 to +50° C., are applied as sealants, coating materials or single-side adhesives. The compositions which are used, based on the filler-containing dispersions of the polymer mixture, are notable in processing for improved fixing in the wet and dry state, high heat stability, good adhesion to rubber and, since they are essentially free from organic solvents, plasticizers and resins, by a high level of environment-friendliness.
