Extra NEWARK PLANT PIGMENT COLOR RESEARCH REPORT SUBJECT: DEVELOPMENT OF "KROLOR" ORANGE YELIDW, K0-789-D PERIOD COVERED: September, 1966 to July, 1968 (part time) SUBMITTED BY: APPROVED BY: DATE SUBMITTED; 9/6/68 LA DATE RELEASED: 9/11/68 ABSTRACT This report is concerned with the development of an orange shade molybdate red (light, yellow masatone and strong yellow tint) "Krolor"-type pigment for use In plastic and paint trades. The excellent combination of light stability and chemical and thermal resistance should lead to other applications for this product. DUP050028312 I, INTRODUCTION The introduction of the "Krolor" line (silica-coated chrome yellows and oranges) to the trade provided new outlets for our chrome yellows and molybdate reds. Fullest exploitation of this line of products necessitates having the widest possible range of colors and properties. Sales requested the development of a "Krolor" based on a lighter mas stone-s tronger yellower tint type product such as YE-421-D to expand the "Krolor" line based on YE-698-D, which is the base for "Krolors" KO-777 and KO-786. II. SUMMARY AND CONCLUSIONS 1, A shipping lot (SL-90787-1) has been set up as a tempor ary standard for this code. This product appears adequate in properties for the plastics trade; but may not yield high enough gloss levels for some paint applications. Sales' present thoughts for paint use involve universal colorants where gloss is not a problem. References #5, 11, 2. Samples of calcium Staybelite treated (SW-00278) and zinc Staybelite treated (SW-00306-l) have been prepared and evaluated at Newark and Chestnut Run. Both products show markedly improved gloss levels in paint systems, with the zinc Staybelite product being preferred because of a tendency toward soft films (after baking or air drying) exhibited by the calcium-treated products. Calcium and Zinc Staybelite-treated pigments cause gelation in vinyl solution (VYHH/VMCH) systems not shown by products treated with Emory 3554D/Igepal C0630 only. Reference #12, 3, K0-789-D types not treated with zinc or calcium Staybelite are markedly superior to other calcium Staybelite-treated "Krolors" in laminates where water dispersibility is a factor. 4. The utilization of presscake instead of dry color has not been successful. No real explanation has been found for this. This finding also applies to other chrome yellows and oranges utilized in "Krolor" manufacture. III. RECOMMENDATIONS FOR FUTURE WORK 1. If the sales developments on this code demonstrate the need for improvements in gloss levels, the scale-up of the zinc Staybelite-treated type product (SW-00306-1) is recommended. 2. For applications where higher water dispersibility is needed, "Krolors" may be treated with Emory 3554/lgepal C0630 combinations Instead of Staybelite treatment. These will re sult in better dispersions. Samples of these types based on "Krolor" Orange Y and "Krolor" medium yellow (1848-50D,E) have been submitted to Chestnut Run for evaluation.
