Abstract

1348006 Coated products BAYER AG 14 July 1971 [18 July 1970] 33041/71 Heading B2E [Also in Divisions B5 C3 D1-D2] Substrates such as bonded webbing textiles and skiver may be coated with aqueous suspensions or pastes of fibrous internally crosslinked particles prepared by reacting aqueous solutions of a polyamine containing at least 3 primary and/or secondary amino groups with a polyurethane or polyurethane/polyurea prepolymer which contains ionic groups and free NCO groups and of which 60 to 90% by weight comprises 1,6-hexane diol polycarbonate units of the general formula:- wherein n is an integer from 5 to 20 (see Division C3). In specific Examples, (17) a paste prepared as described above and containing a thickening agent is applied to a bleached cotton nettle fabric and dried to form a porous coating thereon, (18) a pigmented paste is applied to a chromium plated sheet of metal, a cotton circular-knit fabric being applied to the layer whilst it is still moist. The composite material is then dried, cooled and then detached from the sheet of metal to provide a porous composite material.
