Abstract

1,236,614. Two layer enamelling by a single stoving. FARBENFABRIKEN BAYER A.G. 17 June, 1968 [7 July, 1967], No. 28655/68. Heading C1M. In a two-layer enamelling process by a single stoving a primer enamel slip is applied to the object, e.g. a metal such as sheet steel, to be enamelled and dried, a surface enamel is then applied and the two layers are stoved, generally at a temperature of 720‹ to 820‹ C. The primer enamel slip, which may be sprayed on to the object as a finely ground suspension in a very thin layer, comprises a finely divided primer enamel frit and 1 to 4% by weight of at least one aluminate and 2 to 15% by weight of at least one phosphate. Suitable phosphates are the ortho-, poly-, and metaphosphates of Li, Na, K, Mg, Ca, Sr, Ba, Zn, Al, Fe, Co and/or Ni and suitable aluminates include alkali metal aluminates, aluminium hydroxide, aluminium oxide hydrates and gamma Al 2 O 3 . Adhesion of the primer may be improved by adding to the slip metal oxides or hydroxides. The surface enamel may be white, coloured or transparent. In the examples the primer enamel frit has the following compositions in per cent by weight:-SiO 2 : 39À5, 42; Al 2 O 3 : 5, 6; B 2 O 3 : 19, 17; Na 2 O: 19, 19; K 2 O: 4, 4; F: 2, 2; CaO: 6, 6; NiO: 3, 3; CoO: 1À5, 1: P 2 O 5 : 1, 0. The slips are free of conventional mill additives such as quartz or clay or have a much lower content of these additives.
