Lab #2651 H. R, SGKRAFER NUBIAN Hammond Lead8 s P-7 Pigment Since It may be of general interest, we are summarizing. Immediately following oh the next page, our experience with the P-7 lead silicate pigment from Hammond Lead. (Summary is on next page.) GLD006782 -78- July, 1964 Raw Materials Our use of P-7 has been in the Direct-to-Metal Freight CaT Paints to the greatest extent. Gail Schooley's reports in the January 1963 (page 11) and October 1963 (page 31) PDR*s cover a number of products which use it. It has been tried in appliance primers (laundry) and found to be less effective than Tri Calcium Phosphate (W-224). The exception, of course, is in SW-6530, a White Flash Dry Primer for Admiral (freezers, air conditioners) in vfaich its use helped salt spray. However, we have sold only a drum or so. We also have it in SW-6621-A, a White Flovcoat Enamel (baking) for Lloyd Mfg. Co. Difficulty with the flowcoating operation has limited sale of product which is used for coating outdoor furniture. KEITH PIPER READING Hi-Sil #233 from Columbia Southern (W-R-16) The subject inert material has been substituted by the Wood Finishing Laboratory for Syloid #161 (M-466) in the Glidkote formulations on about a pound-for-pound basis as a flatting agent. They have also found in the Aroflint system, where they grind in the epoxidized oil (Aroflint #303), that they have been able to use about 80% of the amount that they formerly used of Syloid #161. I am bringing this to everyone's attention because the price of the Hi-Sil #233 is 56d a pound less than that of the Syloid #161. * They have been grinding these flatting bases in the Pebble Mill, but it might be that they could be dispersed as well with the Cowles in certain vehicles, if the proper consistency were obtained. I suggest that Hi-Sil #233 be considered for new formulations and as a possible sub stitute for Syloid #161 in existing formulations, whenever possible. H. M. WERNER
