We had restricted- sales We have been successful in promoting Krolor as a `loWer cost alternative to caamium pigments where some compromise in heat'stability can'be tolerated. We.have`been least 'successful'`in the red shade'range'-because our only previous ' Krolor Red, KR-980-D, is among`the least,heat stable Krolor . "i * Krolor Red, KR-981-D is one of the most heat Stable' Krolor-. pigments and it should enjoy a much wider appeal. Also, its superior intensity in both masstone (full shade) and tints will give your customers greater formulating latitude than is available with any other heat resistant red. All this, and savings up to 60%,make this product a valuable addition to our These and other advantages are described and exhibited in a limited number of sales aids. These are en route per the attached distribution and are designed to be used for discussions with customers. There are not enough to give to customers, but a one-page handout with vinyl color swatch is included. About 80% of domestic Krolor sales are to plastics accounts where you will find the bulk of cadmium red sales, superior lightfastftess, chemical resistance and heat stability are also important to segments of the coatings industry. However, V liiu,!- +a . The attached list of customers have already received samples. Of course, we would appreciate any customer feedback that y o u Personnel in our technical service group at Chestnut Run nave considerable experience wirh this product. Please take advantage of their expertise. KR-981-D was included in our March 13th price announcement to customers at $7.75/#.

Red KR-981-D is designed for the high temperature plastics markets currently dominated by high cost cadmium reds. Hear stability in both mosstone and tint is excellent as shown in Exhibits 1 ond 2. And high intensify or both levels gives it greoter formuloring latitude rhon is available in any other heat resistant red. For example, KR-981 -D con be used in blends with Krolor4 Orange R, KO-906-D, to match any intermediate mosstone shode of cadmium ond provide even brighter tints, o well known limitation of codmium reds (See Exhibits 3 and 4). In oil cases, these ore achievable at lower cost (See Tobies I ond II). Besides volue, brightness of shode, and heot stability, KR-981-D: p Has excellent dispersibility. # Has superior lightfasrness, especially in tints where cadmium pigments ore deficient. Is low dusting. The brightness and heat stability of KR-981-D, in both mosstone ond tint, ore superior to our original Krolor Red, KR-980-D. The exhibits illustrate both of these points - especially in tint. However, KR-980-D can be used for its still lower cost in situations where its limitations present no problem, e. g., mostly in olefin applications.

Concentrates of each pigment were prepared at 20% loadings in Cylcolac* TO-1000 resin on a 2-roll mill and reduced to final pigment levels in a Banbury in rhe same resin. These were molded at 450, 500 and 550F using a molding cycle which subjects rhe plastic to o five-minute dwell rime at each temperature. Color and Cost (Tables I ond I! and Exhibits 0 and 4) Color and cost comparisons between a codmium medium dark red toner and 0 matching blend of KR-981-D/KO-906-D, ond cadmium light red toner and ;; KO-906-D ere shown in ABS. These chips were also prepared from 20% 2-roll mill color concentrates let-down to final pigment levels in a Banbury,- they were molded at 450F using the same procedure described for hear stability tests. All intermediate shades of cadmium red between rhe blue shade Codmium Medium Dark Red and rhe yellow shade Cadmium lighr Red can be approximated with blends of KR-981-D/KO-906-D. 4 DUP050071236 TINT HEAT STABILITY KPv-981-D IK1ADS G0 QOi cO C O O' ct X J3 1 0 T3 3 I, & *5 * gy- *crii 0)If) Vt*O> r39o* y2~ Sit- 'fV?);: X2uD. ^lO * > .. iG.
