T, Gottesman At Piscataway from pt Buono At Piscataway Subject MONTHLY SUHMARY - MAY 1973 Date Hay 31, 1973 Copy to I. COATINGS INDUSTRY A. Microbiocides 1. Biocide and Compatibility Screening (E. DiBella, P. Minieri, H. Sidi, G. Trautenberg, G. Tirpak, G. Kagan, M. Landau) (a) TIP Candidate Compounds Fifty eight TID compounds underwent initial biocide screen ing this month. Fourteen of these, which included several maleimide and morpholine derivatives, showed significant broad spectrum biocidal activity at 2%. Paint incompa tibilities, other than moderate pH changes, were not apparent. Lower level testing has been initiated. An additional eight compounds, of the formaldehyde-releasing type, were found to have excellent bactericidal activity. These materials will be evaluated for paint stability and, if warranted, will undergo can preservative evaluation. * Paint compatibility studies on the following four TID compounds have been completed: (1) ^-Dimethylaminopropiophenone hydrochloride (2) O-anisaldehyde,N-raethylhydrazone (3) N-hydroxyraethyl-5-chlorobenzotriazole (4) Morpholine,N-(methylbenzimidaz l-yl)methyl: Ethylene Glycol The first three candidates failed to pass paint compati bility tests (pH, yellowness, and/or viscosity problems) either initially or after aging one month at 120F in both latex systems. Morpholine,N-(methylbenzimidaz l-yl)methyl: Ethylene glycol gave a high initial pH in the PVA test paint but exhibited no other adverse responses. It will be exposed for outdoor fungicidal activity. COLOR!TE 011771 MONTHLY SUMMARY - MAY 1973 -2- May 31, 1973 (b) Tenneco Pasadena Laboratory Candidate Compounds Four candidates (shown below) submitted by the Pasadena Laboratory are undergoing paint compatibility. (1) 1-Phenyl-2,3-dibromo-2-propene-l-one (2) l-Phenyl-2-butyne-l-ol (3) 4-Phenyl-3-butyn-2-one (4) 1-Pheny1-2-butyn-l-one Evaluation in the acrylic test paint indicates that only 1-Pheny1-2,3-dibromo-2-propene-l-one and 1-Pheny1-2-butyn-l-one at 0.1% gave an acceptable performance. Testing in the PVA is in progress. * (c) Chevron Candidate Compounds Chevron compounds NU-74-3 and NU-4-5 are being evaluated in vinyl films. Initial zone of inhibition tests indicate both compounds are superior to Fungitrol 11. Weatherability and surface fungal resistance evaluations are underway. * 2. Competitive Products (G. Trautenberg, G. Tirpak, G. Kagan, M. Landau) (a) Troy Chemical Corporation Paint compatibility studies of three competitive biocides, Troysan 142, 174 and an experimental Troy product coded 192 at 0.1, 0.2, and 0.4% in PVA and acrylic paint have been completed. Troysan 142 imparts an objectionable odor at all levels and yellows the paints to an unacceptable degree at 0.2 and 0.4% after aging for one month at 120F. Troysan 174 increases initial pH to an unacceptable level in the PVA and also shows unacceptable yellowing on aging in the PVA and at 0.4% in the acrylic, Troysan 192 imparts a high initial pH level in the PVA and acrylic but does not appear to have any other adverse effects on either paint. Can preservative evaluations of the Troy products indicate that both 142 and 192 are superior to Nuosept 77 (at an equal biocide level). Nuosept 77 outperforms Troysan 174. Based on the paint performance and excellent biocidal activity of Troysan 192, this experimental product would effectively compete with Nuosept 77. COLORITE 011772 MONTHLY SUMMARY - MAY 1973 3- May 31, 1973 (b) Witco Chemical Corporation Keycide X-10, 127. bis (tributyltin)oxide, was found to be identical to Mildewcide X-10, previously manufactured by Key Chemicals. This material was previously evaluated and was not considered to be competitive to either Super Ad-It or Fungitrol 11. In addition, the material did not show efficacy as a can preservative. * 3. Fungitrol 11 (G. Kagan, M. Landau) Dispersion Studies Stability tests of Fungitrol 11 dispersions in Nuosperse 657 and mineral spirits have indicated that two systems look promising from the standpoint of viscosity stability after aging for two weeks at 120F. These systems which contain 50 and 55% Fungitrol 11 compound on total dispersion also exhibit acceptable viscosity stability after aging at -20F and room temperature. A system with 60% Fungitrol 11 shows unacceptable viscosity stability after aging for two weeks at 120F. Additional preparations of the 50 and 55% Fungitrol 11 dispersions have beenmade to gain more experience with the preparation and viscosity stability characteristics of these systems. In addition, comparative fungicidal efficacy (after aging) of the dispersions vs. the powdered form will be determined. * 4. Fungitrol-22 (G. Trautenberg, G. Tirpak) Initial zone tests and surface fungal resistance evaluations indicate no biocidal advantage by addition of bis(trichloromethyl)sulfone (the additive in Vinyzene BP-10) or dodecyl dimethyl benzyl ammonium naphthenate (Nuodex 100VT) to Fungitrol-22. 5. A5IM - Can Stability Test (G. Trautenberg, G. Tirpak) Our portion of the "round-robin" testing of various can preserv ative bacterial cultures has been completed. Hie Pseudomonas culture used by most laboratories appears to be the "best" (good viability and viscosity loss) Gram (-) microorganism and the three Tenneco Bacillus species are the best Gram (+) micro organisms. These results will be reported at the June ASTM committee meeting. COLORITE 011773 MONTHLY SUMMARY - MAY 1973 4 May 31, 1973 \ B. Driers (G. Kagan, M. Landau) * 1. Loss-of-Dry Inhibitor Blends of 1.2% Cobalt/2.1% Calcium/3.2% Zinc at 27. on vehicle solids and 0.6% Cobalt/2.1% Calcium/3.27. Zinc at 2% and 37. on vehicle solids provided non-staining films, acceptable initial drying times and loss-of-dry inhibition after one month aging when compared to Nuact and Mooney's Lead-Free Feeder Drier. A number of preparations of a red and a black enamel have been made to corroborate these results. Several experimental systems, including a green trim enamel, a white enamel and a white linseed oil house paint for which loss-of-dry is anticipated, are being included in the program. Preliminary cost calculations indicate that both the above blends would be competitive to Nuact. 2. Water Dispersible Driers Previous evaluations in a black baking enamel of Cyclodex Cobalt 67., Lead 24%, Zirconium 12%,, and Calcium 4 and 67. showed functional equivalency comparable to Cincinnati Milacron Advacar water dispersible driers. Evaluation of the above driers (room temperature and aged samples) in air dry formulations indicates that the Cyclodex materials are comparable to the Advacar line in viscosity, pH, hardness, gloss, and drying time. Aging studies of the paints for one month at 120F are underway. (An orange air dry enamel used to evaluate manganese driers flocculated after one month at 120F with and without driers). XI. LUBRICANTS A. Plastics Compatible Lubricants (M. Knapp) Eleven fluids have been evaluated for their effect on stressed polystyrene by Tenneco Functional Method FL-9. None of the fluids (three IMP, six succinate, one acetate, and one phthalate deriva tive) showed acceptable plastics compatibility. * B. Lubricant Additives (M. Knapp) Nine extreme pressure additives from U.S.D.A. have been screened for both load-carrying and high temperature performance* Of these, one compound, 2-(2-ethoxyethoxy)ethyl 9,10-epithiostearate, shows promise and will be investigated further.

Knapp) - continued Three EP additives from Keil Chemical have been screened for load carrying only and performed well. However, it is suspected that these materials will be found to have poor oxidation stability because of their high degree of chlorination. These tests are underway. C. Competitive Product Evaluation (M. Knapp) Fiske Brothers' Lubriplate AC-3 compressor lubricant was evaluated to determine if it could be competitive to ANDEROL 500. It was found to have several deficiencies (poorer stability, lower flash point, poorer demulsibility) as shown below: LABORATORY EVALUATION OF LPBRIPLATE AC-3 COMPRESSOR OIL Property Lubriplate AC-3 ANDEROL 500 Base Fluid Type Color Viscosity @100F, cSt Viscosity @210F, cSt Viscosity Index Pour Point, F Flash Point, F Evaporation, 22 Hours @210F, % Petroleum Dark Amber 153.3 14.2 98 +14 450 0.3 Diester Light Amber 106 9.3 61 -30 510 0.8 Demulsibility @130F, ASTM D1401 ml oil/ml water/ml emulsion (rain.) 0/0/80 (60) 39/38/3 (60) Oxidation/Corrosion, Tenneco Method FL-8, 24 Hours @190C Viscosity Change, % Acid Number Change Sludge, mg/gm oil Effect on: Copper Steel Aluminum Magnesium Silver +16.9 +0.65 1.6 Corrosion Light Tarnish No Change No Change Corrosion +5.5 +0.3 0.1 Light Tarnish Light Tarnish No Change No Change No Change Four-Ball Wear, 40 kg, 1200 rpm, 167F, 1 Hour, mm Four-Ball EP, Weld Point, kg Falex EP, Failure, lbs. 0.8 170 900 0.8 100 1150 COLORITE 011775 MONTHLY SUMMARY - MAY 1973 -6 - May 31, 1973 S \ * D. Two Cycle Engine Lubricants (M.
