Abstract

1508992 Powder paint compositions UNILEVER Ltd 12 June 1975 [11 April 1974] 16213/74 Headings C3B and C3R A powder paint composition comprises as matting agent a siliceous material (S) of porevolume 0À2-0-8 cc./g. (S) may have average particle size 1-100 Ám. and oil absorption 50-130 g. oil/100 g. (S). (S) may be silica gel or an SiO2/Al2O3 composition of the cracking- catalyst type, e.g. comprising 13 or25%Al2O3. 7À5- 16 % wt. (S) may be added to a conventional paint composition, which may be epoxy-resin or polyurethane based and may be black.
