BARTOLO * i i, 1^ INTRODUCTION 1 AURD 11-75 (First & Final Report); MONASTRAL BLUE G, BT-476-D IN PLASTICS fa- $ ;lvS ' Two lots of Monastral Blue G, BT-476-D were*submitted for evaluation in plastic systems to assess their suitability as counterofferings for the major Blue G competitives. - ,. , .< 0, Evaluations were made for dispersibility in soft vinyl, heat stability in high density polyethylene and for color properties by varnish dryer rubouts. .American Cyanaraid and Du Pont codes were used for comparisons. ;fe CONCLUSIONS ' S'-M- `Additional effort should be directed to provide a product at least equal in performance to American Cyanamid 55-3297. BT--476-D, Lot 55468, the best Du Pont product evaluated, is deficient primarily in strength and intensity. While suitable dispersibility, strength, heat stability and intensity is available among Du Pont codes, no single product has an adequate level of these attributes. rh>i< 1 SL_ 'V , The* economics for manufacture of BT-476-D should be reviewed to ' "> , determine if it can be profitably sold at a lower than standard price.
