Textured coatings: more than just a pretty face Available to Purchase

Extract from a recent paper presented by Peter Longbottom, Association of British Textured Coating Manufacturers Textured coatings were developed at the end of the second world war in America. Whether this was for concooning Liberty ships or to reduce the condensation in their holds is immaterial. Logically, for either job, a thick film coating was required, sufficiently viscous not to sag on application. For this, brush application was unsuitable and application by heavy duty spray equipment essential. Once the brushability constraint had been removed, the opportunity of introducing high bulk, low density fillers, became possible and economically essential. Expanded perlite was a natural choice and the coarser grades gave a texture to the coating. Long fibre asbestos was also appropriate to thicken the coating and this imparted some measure of resistance to cracking.
