Biocide and Compatibility Screening (E. DiBella, P. Minieri, G. Trautenberg, G. Tirpak) (a) TOP Candidates Biocide screening was completed on sixteen TOP candidates. None showed significant promise as can preservatives or fungicides. Extensive evaluations have been completed on five raaleimide candidates under consideration as vinyl biocides. The prime paint fungicide candidate, 2,6-Diethylphenyl maleimide, shows the most promise with efficacy superior to Fungitrol 11V, but not to Vinyzene BP-5. Should the toxicity of this material prove acceptable and current efficacy as a latex paint fungicide be maintained, limited customer sampling as a zone forming alternative to Fungitrol 11V can be initiated. 2. Can Preservative Formal EPA efficacy, toxicity and chemistry protocols on Nuosept 95 have been submitted and are awaiting approval. B. Driers 1. Calcium Based LOP Inhibitor (L. Schinasi, G. Kagan, M. Landau) % Drying tests in paints after two months' aging at 120F of four TOP prepared experimental 7% calcium based loss-of-dry inhibitors, indicate a preparation of Canadian naphthenic acid and 37. Nuvis HS (D050-65) is the most promising candidate in preventing loss-ofdry (see table below).

In addition, both samples are not photosensitive in this same white enamel. At the request of Marketing as discussed at the recent Paint Industry Task Force Meeting, current studies on this product will be finished but no further work will be initiated. C. Nuosperse HOH (G. Kagan, M. Landau) In view of a potential water sensitivity problem (adhesion) with Nuosperse HOH uncovered by DeSoto with their Dew-Freeze-Vacuum test procedure, materials and equipment are being collected to evaluate Nuosperse HOH vs. Tamol 731 using this procedure. This test may also help to clarify another potential problem with Nuosperse HOH in semigloss (low gloss) paints reported by Sherwin-Williams. D. Other Additives (G. Kagan, G. Trautenberg) During the latter part of May, Mr. Leo Felt, an independent inventor, visited the laboratory to demonstrate an additive for alkyd enamels which would permit the dilution of the paints (for substantial cost reduction) by 45% using water (30%) and mineral spirits (157.). Mr. Felt claimed that the "diluted" enamel performance would be generally upgraded by the prior addition of 5% of his additive. Evaluations have shown that most of the paint characteristics, i.e., viscosity, grind, optical characteristics and initial gloss of a commercial enamel modified with Mr. Feit's additive was comparable to that of the unmodified enamel. However, after aging for one week at 120F, the modified material lost most of its gloss (18-20 units) while the control showed essentially no change. Exposure of these enamels in a Weath'erometer for 32 hours also showed an unacceptable loss of gloss for the modified enamel. COLORITE 01X642 MONTHLY SUMMARY - JUNE 1974 *> \ -3- June 24, 1974 D. Other Additives (continued) It hag been concluded, particularly in view of the unfavorable gloss responses, that Mr, Feit's additive, with respect to paint dilution, would not be acceptable for promotion to the Paint Industry. Since he also claimed that his additive would be effective as a can pre servative and mildewcide, it has been evaluated in an alkyd enamel and PVA paint to determine the efficacy of the product for these applications. Results indicate that it is not effective as a can preservative and leached paint films show no fungicidal activity. Based on these results, no further work is warranted. II. LUBRICANTS * A. Crankcase Lubricants (M. H. Knapp, R. G. Sknith) An agreement has been reached with Chevron Chemical Company for the cooperative development and testing of an SE crankcase oil. Several oil blend samples, including engine test retains, plus used test engine parts have been sent to their research laboratory at Richmond, California, for analysis and evaluation. Initial results of these tests are expected by mid-July. At this time a cost-shared engine test program will be developed. Ultrachem's Qiemlube 10W/40 has been evaluated and is being analyzed. Initial analytical results indicate that although it is based on DTDA (as both our candidate and Amzoll are), it appears that there are significant differences in the additive system. It is possible that they are using Lubrizol additives rather than a Chevron package. The laboratory evaluation shows that the Chemlube oil has comparable physical properties to both Amzoil and low ash Anderol 472. The performance in the FL-10 bearing corrosion test appears to be signif icantly poorer than Amzoil. The bearing appearance was comparable to that produced by the Anderol 472 (tfiich contains Lubrizol additives). The significance of these bench test results is not known, however, since no direct correlation between these tests and engine performance has been established.

Fischer) CQNRDSNTIAI. These papers contain confidential matters which are the exclusive property of Tennoco Chemicals, Inc. No extract-, therefrom or any use or disclosure thereof may be made except upon proper authorization and for the sole benefit of Tonneco Chemicals, Inc. A successful plant run has been carried out at Elizabeth utilizing the new Manganese 12% formulation based on the use of n-heptanoic, 2-ethyl hexoic and neodecanoic acids. A sample was forwarded to Apollo Chemical for their evaluation. A gelation problem encountered by Nutmeg Chemical Co. in blends of NuXtra Iron 9%, magnesium naphthenate 6% and calcium Naphthenate 5% (the latter not our product) was shown to be due to the calcium soap and readily correctible by addition of a small amount of 2-ethylhexoic acid. The customer was so advised. A sample of an experimental calcium naphthenate prepared from crude naphthenic apid which showed no gela tion problems when blended according to the Nutmeg formulation was supplied for their evaluation. II. PLASTICS INDUSTRY A. Additives 1. Tin Stabilizers (S. Hoch, M. Spalding, E. Szabo, M. Ceprini, R. Caruso). A dibutyltin oxide (DBTQ) submitted by Albright & Wilson was evaluated as a raw material by conversion to V-1562 and BD-600. Functional evaluations against our standard products indicated the DBTO to be suitable. The direct blending of V-1420, 1-167 and V-1562 at ambient temper ature was found to yield an acceptable V-1766 equal to that previously prepared from V-1420 and V-1528. This represents a simpler procedure and may* be of use in avoiding the periodic haze problem encountered in plant preparations of V-1766. A drum of functionally acceptable R-322 (dibutyltin bis dodecylmercaptide) was prepared in the pilot plant and shipped to Hampshire Manufacturing for evaluation. COLORITE 011645 A BD-602 (match to Argus Mark 1044) prepared from Conoco's Alfol 1216 'yielded a product of equivalent functionality. A tridecyl alcohol based version was also prepared and is being evaluated. A shortage of Neodol 25 normally used in BD-602 has prompted this investigation for alternate alcohols. Liquid Stabilizers (S. Hoch, R. Lally, J. Dunn) A barium stabilizer of 23% metal content based on a barium nonylphenate-tallate-carbonate system in which Ultrol 8 (a mineral oil type) is utilized as a diluent was developed as a replacement for Lubrizol 2106, a product in short supply. Evaluation on an equal metal content basis indicated comparable functionality (including plate-out characteristics) to the Lubrizol product which shows a 27% barium content. Attempts will continue to attain a 27% metal product to allow substitution on a pound for pound basis. Powder Stabilizers (S. Hoch, S. Kaplan) The Piscataway Stearate Plant carried out a preparation of 1-282 (cadmium pelargonate) based on,a recent R & D procedure without any processing problems. A sample of this product was blended in the laboratory to 1-237 and 1-248 types and these were found functionally equivalent to control samples when evaluated at Flemington. Since this approach represents simpler processing, its use in the stearate plant has been recommended. As a result of a shortage of N-99, a surfactant utilized in the Piscataway Stearate Plant to control extrusion characteristics, the laboratory has undertaken an evaluation of surfactants to develop alternates for this use. BASF-Wyandotte's Pluronic 104 was,found to give excellent results with both calcium and zinc stearates. Atlas's Renex 20 and Brij 96 in a 1:1 mix gave good results with zinc, but poor with calcium stearates. Flame-Retardants (E. DiBella, M. Reale, H. Sidi, H. Gould, R. Caruso) The pilot plant has prepared 131 pounds of our R-525 candidate for flexible polyurethane foam, viz. bis(l,3-dichloropropyl tribromoneopentyl phosphate. Product properties including functional evaluation in foam were satisfactory and the material has been sent to Foam and Plastics for lab-line evaluation. Our evaluation of Thermolin 101, ethylenedioxy bis(bis(2-chloroethyl)phosphate)in both high and low density polyether and poly ester foams indicate that'this new product offering by Olin is about twice as efficient as Fyrol-2. Further testing of this material at Foam and Plastics has been recommended. COLORITE 011646
