These protective coatings are flame retardant, corrosion resistant, chemical resistant, (to acids, alkalies, and water), and have good electrical insulating properties. When properly pigmented, these coatings have unusually good weatherability. Chlorinated-rubber films plasticized with an Aroclor compound grip common structural materials in strong adhesive bonds, and the addition of an Aroclor compound improves the flexibility and life of chlorinated-rubber coatings. The formulations suggested in this bulletin are given as stalling points or guides for development of new formulations that capitalize on the outstanding qualities of these compounds. 01*521? 5 TOWOLDMONOQ23374 NUMBERING AROCLOR COMPOUNDS The first two digits of the number of an Aroclor compound represent its molecular type, as: 12 chlorinated biphenyls 44 blend of chlorinated biphenyls and chlorinated terphenyls 54 chlorinated terphenyls The last two digits indicate the weight percentage of chlorine in the product. For example: Aroclor 1248 is a chlorinated biphenyl that contains 48-weight-pcr cent chlorine Aroclor 5460 is a chlorinated terphenyl with 60-weight-per cent chlorine The physical properties of the Aroclor plasticizers vary gradually with the degree of chlorination. Compounds with low percentages of chlo rine, such as Aroclor 3221 and 3232, are clear and very fluid. Aroclor 3242, with 42-per cent chlorine, resembles vegetable oil; the product with 48-per cent chlorine is slightly more viscous and looks like a medium-grade mineral oil. At 54-per cent chlorine, the compound is quite viscous. At higher chlorine percentages, the chlorinated biphenyls become gumlike. At 68-per cent chlorine, the range is complete; Aroclor 1268 is a white powder. Both chlorinated terphenyls (Aroclor 5442 and 5460) are yellow solids. The gradual change in physical properties often allows a processor to select a plasticizer particularly suited for his operation. If a dry mix is desired, Aroclor 3268 acts as a flame retarding filler. It is also pos sible to use it as a solvent-plasticizer at higher processing temperatures. Complete physical properties and specifications for the Aroclor com pounds are listed in technical bulletin O/PL-306, "Aroclor Plasticizers." PROPERTIES OF CHLORINATED RUBBER Chlorinated-rubber-based coatings are used extensively for resistance to corrosion, moisture, fungus, mold, and other destructive agents. Parlon \ chlorinated rubber is a mixture of two polymers, with an average chlorine content of 67-per cent, made by chlorination of natural rubber. Its typical properties, according to the manufacturer, Hercules Inc., Wilmington, Delaware, are listed in Table I: 1 Tdtfemrk at Httculti.

To make chemical- and corrosion-resistant coatings, the modifiers must likewise be nonreactive with acids, alkalies, and salts. As little as five per cent of a saponifiable material, such as linseed oil, alkyd resin, or ester plasticizer, seriously detracts from the alkali resistance of the finished coating. Monsanto compounds, such as Aroclor 5460 and Aroclor 1254 or 1260, are the best available plasticizing resin and plasticizers, respectively, since they are unaffected by acids, alkalies, or salts. The following table summarizes some of the benefits imparted to chlorinatedrubber coatings by Aroclor plasticizers: TABLE 4 -- Benefits of Aroclor Plasticizers in Chlorinated Rubber GOOD ADHESION TO RESISTANCE TO AlumAroclor Inum Steel Transite Cello phene m s% Hydro- Sodium Sodium chloric Hydrox- Chlor- Acid ide ide Water ColdSward Check Hard- Resist- ness ance 1254 - - X X XX X X 35 3 x; X1 1 :i i 1260 XX X X 40 4 X X X 1 5460 XX X X 22 2 Aroclor 1262 and 5460, resinous types, show good compatibility in chlorinated-rubber films laid down from toluene solution containing 20-per cent of the plastic in ratios of 2:1 and 1:1 (Parlon to Aroclor). The plasticizer types, Aroclor 1252, 1254, and 1260, also have good compatibility.

Inc. | 11 0145217 TOWOLDMONOQ23379 The Aroclor compounds imparl the following advantages to the films cast from these lacquers: Adhesion Unplasticized chlorinated-rubber films have very poor adhesion. The lacquer film containing Aroclor 54G0 adheres well to aluminum, bare steel, primed steel, galvanized iron, and Transite surfaces. The lacquer films plasticized with Aroclor 1254 or 1260 give good adhesion to Trans ite, cellophane, galvanized iron, and primed-steel surfaces. Though compounds with an Aroclor alone possess pronounced adhe sion qualities, better adhesion to all of the surfaces results if mixt ures of Aroclor or varied contents are used. Resistance to Aqueous Solutions Chlorinated-rubber films with Aroclor 1254 or 1260 (plasticizers) and Aroclor 5460 (resin) show satisfactory resistance to solutions of 10-per cent hydrochloric acid, 5-per cent sodium hydroxide, 5-per cent sodium chloride, and water-spot tests. Film Hardness Softer films are produced with Aroclor 5460 in ratios of 5:10 and 10:10 (Aroclor and Parlon) than with other commercial resins in similar mixtures. Likewise, softer films result from Aroclor 1254 or 1260 in ratios of 2:10 and 5:30 (Aroclor and Parlon) than with other com mercial plasticizers at these concentrations. These tests show that Aroclor compounds have strong plasticizing action on chlorinated rubber. Cold-Check Resistance Aroclor 5460 is superior to phenol-formaldehyde resins in cold-check resistance imparted to chlorinated-rubber films, but not as good as long-oil-alkyd modification. Aroclor 3260 is a somewhat better plasti cizer than Aroclor 1254. Weather Resistance Pigmented chlorinated-rubber finishes containing Aroclor have con sistently withstood outdoor weather tests, but unpigmented finishes do not weather well regardless of the resin or plasticizer used. Poor resistance to ultraviolet light is also a weakness of chlorinated rubber. Most pigments (except ultramarine blue) are usable with Parlon and are recommended if the coating is to be subjected to outdoor weather or ultraviolet light. However, pigment protection varies con siderably. Inspection of alkyd enamels fortified with Parlon showed weatherability varied from 63 months with chrome green to 4 months for titanium dioxide-iron blue combinations. Sanding and Polishing Properties Plastic films compounded with Parlon and Aroclor 5460, 1254, or 1260 have shown satisfactory sanding and polishing characteristics. OH5218 11 TOWOLDMONOQ23380 APPLICATIONS Alkali-Resistant Coatings Products containing Aroclor and chlorinated rubber are highly resist ant to alkalies and moisture. Paints with combinations of Aroclor and chlorinated rubber are used in large quantities for concrete floors, walls, swimming pools, and other surfaces.

The technique utilizes the physical properties of trichloroethylene, the only solvent in the paint. Metal parts enter the unit covered with grease and leave the other end completely painted and dry to the touch. Detailed information about the process can be obtained from E. I. DuPont de Nemours & Co., Inc., Wilmington, Delaware. The formulation in Table 8 has given good characteristics in this con tinuous-painting system: TABLE 8 -- Formulation for Continuous-Painting Process Ingredients Parlonj (20-cp) chlorinated rubber Long-oil, drying, alkyd resin Aroclor 1254 Titanium Dioxide (Rutile) Bentone* 38 gelling agent Epoxy stabilizer Trichloroethylene *) Add pljmenl dlspouion to vohidt itiir 24 hours fn ptbble mill b) Add jelllr>( ijent to plfmonl dispersion durlni lest two hours ol (rind Parts by Weight Pigment0 Vehicle Dispersion 100 15 23.7 50 100 1.256 3.9 217 53.5 Marine Finishes The marine industry makes great use of chlorinated-rubber coatings plasticized with Aroclor compounds to protect wood and metal on boats, barges, and other marine equipment. They resist salt water, and their hard finish deters algae and other marine growth.

TOWOLDMONOQ23383 Emulsion Paints If chemical resistance is required on porous surfaces, Aroclor 3254 is often added to chlorinatcd-rubber-emulsion paints. Hercules, Inc. reports that preferred water phases for such paints are either a 1-per cent-djstilled-water solution of Aerosol* OT or a 4-per cent-distilledwater solution of sodium oleate. A lacquer-to-water weight ratio of 2.5 to 3 is suggested for the complete emulsion. Chlorinated rubber of any viscosity may be used. A typical lacquer phase for such an emulsion paint is given in Table 10: TABLE 10 -- Formulation for Lacquer Phase of Emulsion Paint Ingredients Parlont chlorinated rubber Aroclor 1254 Aroclor 5460 Xylene Hi-Flash naphtha Parts by Weight 28 14 10 24 24 Mastics Mastic compositions are used to deposit thick films with a minimum number of coats. Mastics modified with Aroclor compounds can ef fectively seal cracks in concrete, smooth rough concrete surfaces for subsequent glossy coatings, give excellent corrosion resistance under severe conditions, and retard fire. A typical starting formulation is given in Table 13: TABLE 11 -- Mastic Composition Ingredients Parlont (20-cp) chlorinated rubber Aroclor 1254 Aroclor 5460 Asbestos Titanium Dioxide (Rutile) Toluene Parts by Weight 100 30 49 160 25 300 Although this mastic formulation adheres well to either wood or masonry, a primer is suggested before application to sled. To further increase fire retardance, replacement of 33 parts of the asbestos by 47 parts of antimony oxide is suggested as a starting formulation. ol Heuu'tvIn..

These adhesives are also of unusual interest because they are flame resistant. A typical formulation is given in Table 12: TABLE 12 -- Formulation for Acid- and Flame-Resistant Adhesive Ingredients Parlonf (125-cp) chlorinated rubber Aroclor 1254 Aroclor 1260 Toluene Parts by Weight 20 6 6 68 Electrical Coatings Because of their desirable electrical properties, these compositions are useful for insulating and protecting electrical wire and apparatus from moisture. With selected fungistats and waxes, coatings of this type are used to protect electronic equipment in the tropics against moisture and fungi. The fire retardance of Aroclor and Parlon combina tions is an added dividend in the electrical field. Printing Inks Printing inks requiring fast drying time and chemical resistance are often based on chlorinated-rubber compositions plasticized with an Aroclor compound. These inks are especially useful on soap wrappers and boxes, bottle labels, and many other commodities because of their alkali resistance. 1Tid*rniik of Ktictilts. Inc. 01*5223 TOWOLDMONOQ23385 OTHER MONSANTO PLASTICIZERS COMPATIBLE WITH CHLORINATED RUBBER The following Monsanto plasticizers (Table 13) are also compatible with chlorinated rubber, but none give the over-all desired qualities attained by using an Aroclor plasticizer: TABLE 13 -- Other Monsanto Plasticizers Compatible With Chlorinated Rubber Dibutyl phthalate Diethyl phthalate Dimethyl phthalate Santicizer B-16 plasticizer Santicizer 160 Santicizer M-17 Santolite'H MHP plasticizer Tricresyl phosphate Triphenyl phosphate 0145224 17 r TOWOLDMONOQ23386 TOXICITY AND SAFE HANDLING Inhalation At ordinary temperatures the Aroclor chlorinated polyphenyls have not presented industrial toxicological problems. The hazard of potential toxic exposure varies with their volatility: the lower-chlorinated, more-volatile ones present more of a potential problem from the stand point of both inhalation and skin contact. When Aroclor compounds are used at elevated temperatures, engineering controls must be applied, either by the use of closed systems or by effective local-exhaust ven tilation together with general workroom exhaust. Vapor of the liquid Aroclor compounds at room temperature should not be breathed in a confined space, and no vapor of any Aroclor compound evolved at elevated temperatures should be allowed to be dispersed into the general workroom. Inhalation tests on animals indicate that the maximum safe concentra tion of vapor is in the range of from 0.5 to 1.0 milligram of the lowerchlorinated Aroclor compounds per cubic meter of air. The threshold limit values (maximum allowable concentration for an 8-hour working day) set by the American Conference of Government Hygienists are 1.0 milligram per cubic meter of air for the lower-chlorinated Aroclor compounds and 0.5 milligram per cubic meter of air for the morehighly-chlorinated compounds, such as Aroclor 1254. Skin Contact Schwartz patch tests on 200 volunteers showed that Aroclor 1254 was neither a primary skin irritant or a sensitizer. Prolonged or repeated skin contact with the Aroclor compounds must be avoided by the use of gloves and protective garments, because of the possible occurrence of a condition called chloracne. Although reports of this condition caused by Aroclor compounds are rare, it can be produced by excessive skin contact. It any Aroclor compound is spilled on the skin, the skin should be washed in the usual manner with a soap solution. A burn caused by contact with a hot Aroclor compound should be treated like any ordinary bum. Aroclor compound adhering to the burned area need not be removed immediately, unless treatment of the burn demands it, in which case either soap and water or repeated washings with a vegetable oil arerecommended. 18 OH5225 TOWOLDMONOQ23387 SHIPPING Freight Classification Aroclor 1221,1243,1242, 1248,1254, 1260,1262.. .Synthetic Resin, Liquid, NOIKN Rail Classification Aroclor 1268, 4465, 5442, 5460.................................Synthetic Resin, Other Than Liquid, NOIHN Truck Classification Aroclor 1268.......................
