Title: Agents suitable for coating, lining and cementing
IPC: B65D85/84
Filed: 1931-08-04
Abstract: An agent suitable for coating, lining or cementing consists of any known artificial resin capable of being hardened and silicon or an acid proof heavy metal silicide such as copper or iron silicide.  The proportion of silicon or silicide may vary between 50 and 300 per cent.  The coatings are chemically resistant and of high thermal conductivity.  They may be applied by spreading, spraying or dipping or with a spatula.  Other fillers such as kaolin, asbestos, sawdust, titanium dioxide, graphite may be included.  In examples, (1) an enamel lining for a metal vessel consists of 55-60 parts of silicon or a silicide and 40-45 parts of a liquid 80 per cent phenol-formaldehyde condensation product, which may be sprayed on, and hardened by a current of hot air; (2) damaged enamelled stirrers or vessels are repaired by using the composition of example (1); (3) heating plates or heating grates of drying chests are covered with the composition of example (1) and hardened by direct heating with steam; (4) a vessel is lined with masonry which is cemented together by a mixture of 70-75 per cent iron silicide and 25-30 of a hardenable artificial resin; (5) damaged ceramic ware is cemented together, and (6) reservoirs, iron gutters and pipes and coated with a mixture according to the invention; (7) to apparatus subjected to liquids containing sulphur compounds, a lining of phenolaldehyde resin and silicon is applied.  Thermometer tubes, boiling tubes, riser tubes, stirrers, covers, heating and cooling coils may also be coated. In some cases, tissues, bandages and the like may be impregnated with the composition and wound on the article concerned. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of silicon carbide as a constituent.  This subject-matter does not appear in the Specification as accepted.ALSO:An agent suitable for coating, lining or cementing consists of any known artificial resin capable of being hardened and silicon or an acidproof heavy metal silicide such as copper or iron silicide.
