NOVEMBER 1972 PIGMENT AND RESIN TECHNOLOGY 25 The reaction of red lead primers wit h Determination of the scratch resistance concentrated ferric sulphate of coated and uncoated plastics K. Dietzel; farbe & lack, Aug. 1972, p. 713 G. Lincke; farbe & lack, Aug. 1972, p. 723 Attempts are made to define hardness and This is an extension of the author's work scratch resistance for plastics, and to develop a presented at Fatipec recently. In this article the author describes that his findings on the reaction testing method. Measuring various materials, it was between ferric sulphate and crystalline red lead also found that the brittle materials such as glass are more scratch resistant. In addition some plastics are applicable for completely cured red lead primer were found which, despite their considerable 'soft coats, if the pigment volume concentration is correct. ness', were practically unscratchable. The distance between the edges of the pigment aggregates is important, and hence the length of the diffusion paths of the vagrant iron salts in the swelled film is critical.

A discussion of test methods, cular importance. experimental designs, and analytical methods to elucidate the interactive effects that these variables have on fungal growth is presented. Particle size classification of plastic powders Diffusion of vapours in organic coatings R. E. Schaller, C. E. Lapple; J. Paint Tech., Aug. 1972, A. Kishimoto; Prog. Org.

For example, the method for tailoring particle size distributions of rate of drying of a paint film is governed by the rate plastic powders.
