Appeal No. 1998-1754
Application 08/555,918
APPENDIX
1. Sprayable dispersion comprising an acrylic acid ester copolymer and a colloidal
chloroprene polymerisate, said dispersion further characterised in that it contains an
amount of boric acid sufficient to improve the initial adhesion force properties of the
dispersion.
7. Process for elastic adhesion of two substrate surfaces, at least one of which is
porous in structure, comprising the steps of: applying a dispersion comprising an
acrylic acid ester copolymer and a colloidal chloroprene polymerisate and further
comprising boric acid in an amount sufficient to improve the initial adhesion force
properties of the dispersion to at least one of the substrate surfaces, and gluing the
substrate surfaces together by laying said surfaces together wet and pressing said
surfaces together with at least 0.1 N/cm2 for at least approximately 0.5 seconds.
11. A sprayable dispersion for bonding two substrate surfaces together, said
dispersion comprising an acrylic acid ester copolymer and a colloidal chloroprene
polymerisate, said acrylic acid ester copolymer and said chloroprene polymerisate
being present in a weight ratio of the acrylic acid ester copolymer to the chloroprene
polymerisate of 1:10 to 1.5:1 and said dispersion further comprising from about 0.1 to
10% by weight of boric acid to improve the initial adhesion force properties of the
dispersion.
