Abstract (en)
[origin: US5421945A] PCT No. PCT/EP29/01229 Sec. 371 Date Feb. 1, 1993 Sec. 102(e) Date Feb. 1, 1993 PCT Filed Jun. 2, 1992 PCT Pub. No. WO92/21817 PCT Pub. Date Dec. 10, 1992.The mass preservation of archives by melting on them a binder combination reinforced with a nonwoven or woven fabric, in which a woven or nonwoven fabric on a supporting belt or supporting roller is impregnated with an aqueous, pollutant-free, self-cross-linking and/or not self-cross-linkable and/or pre-cross-linked dispersion, free of volatile solvents, of a thermoplastic binder with a high film-forming temperature above 60 DEG C., into which dispersion waxes or paraffins, with a concentration-based on the solids portion of the dispersion-of 3 to 10% by weight have been incorporated by hot precipitation, dried and, in conjunction with the substrate that is to be preserved, fused under the action of pressure and temperature by a brief temperature shock at a temperature appreciably exceeding the film-forming temperature to a substrate-sealing film with embedded nonwoven or woven fabric.
