<p>1287944 Coating E I DU PONT DE NEMOURS & CO 1 Oct 1969 [1 Oct 1968 9 July 1969] 48334/69 Heading B2E [Also in Divisions B5 C3 and Dl] Substrates such as elastomers, glass, aluminium, polyamides, acrylics, polyesters and fabrics of cotton, rayon and wool, may be coated with compositions comprising hydroxylatedα-olefin/non conjugated diene polymers containing 0.05 to 5 gram moles of hydroxyl groups per kilogram of polymer, the hydroxyl groups being attached to hydrocarbon side chains, optionally together with pigments, fillers, stabilisers and curing agents. The polymer may be derived from ethylene, propylene, butene-1 and/or pentene-1, and hexadiene-1,4, heptadiene-1,4, heptadiene-1,5, octadiene-1,5, dicyclopentadiene, cyclooctadiene- 1, 5, 5-(1-butenyl)-2-norbornene, 5-ethylidene-2- norbornene and/or 5-methylene-2-norbornene. Exemplified fillers and pigments are clay and carbon black. The curing agent may be a polyisocyanate, phenolic resin, sulphur with zinc oxide and accelerators, a peroxide, or a metal oxide or halide with a long chain fatty acid. In examples (7) rayon fabric is coated five times with a composition of hydroxylated ethylene/ propylene/hexadiene-1,4 copolymer, carbon black, naphthenic oil and 1,1,1-trichloroethane; (8) nylon, polyethylene terehthalate and glass fabrics are coated with compositions as in (7) together with methylene bis(4-phenylisocyanate), (9) nylon and polyethylene terephthalate fabrics are coated with compositions as in (8) in which the carbon black may be replaced by clay; (10) nylon tire cords are coated with compositions as in (8); (11) polyethylene terephthalate films and aluminium foils are coated with three coats of compositions as in (8); and (13) nylon fabrics are coated with compositions comprising aqueous latices of hydroxylated polymer and resorcinol/formaldehyde resin.</p> |
