Abstract
Abstract A readily dryable adhesive binder for particulated rubber and/or plastics compositions comprising from 1% to 10% by weight of a water-solubleformaldehyde polycondensation resin, from 0.5% to 5% by weight of formaldehyde or a compound liberating formaldehyde, and from 85% to 98.5% by weight of a film-forming plastics dispersion; as well as a composition forming a resilient covering comprising from 40% to 75% by weight of particulated rubber and/or plastics and from 25% to 60% by weight of the above adhesive binder.
