A dispersion adhesive comprises a co- or terpolymer having predominantly vinyl acetate units and a high proportion of flameproofing agent based on compounds of aluminium and/or boron. Additives such as process agents and thickeners, suspending agents and wetting agents are added to the dispersion adhesive, which also contains preservatives, antifoams, film-formers and a drying retarder. The dispersion adhesive is particularly suitable for the adhesive bonding of rigid polystyrene foams in the form of films or slabs, it is also used for bonding gypsum plasterboards, wood and cork to a suitable substrate, and for gluing tiles and cement sheets. The specific composition of the dispersion adhesive results in a very broad spectrum of application, a particular advantage being that the dispersion adhesive remains processable over a relatively long period of two or more months, the flame resistance of composites is increased, and it has a high initial adhesive force. |
