[Also in Division C3] Metal substrates, e.g. steel bars, are coated in a fluidised bed process with a dry intimate mixture of 60-95% by weight of a film forming material which can be heated to its sintering temperature with degradation, e.g. a polyester or epoxy resin, and which has a granular size of 0.001 to 0.024" and from 5-40% by weight of fibres (e.g. of glass) having a diameter less than or equal to 0.0005" and an average length 0.01 to 0.10". The resultant composition may have a particle size such that no more than 1% is left on a 20 mesh (U.S. standard) screen. In coating the steel bar may be heated to 200‹C. Epoxy resin coatings may be subsequently cured, e.g. for 2 hours at 200‹C.</p> |
