Monsanto i si u ri AROCLOR Co?y Resins and Plasticizers for Chlorinated Rubber Technical Bulletin 0-124 May, 1957 Momenta Chemical Company, Organic Chemicals Division, SI. Louis 1, Mo. Resins and Plasticizers for Chlorinated Rubber Introduction K4onnio produces t series of chlorinated biphenyls and polyphenyls identified by tbe trademark Arodor" for use as plasticizers and resins for chlorinated rubber base lacquers, varnishes and paints. These protective coatings are fire resistant, corrosion resistant, chemical resistant (to acids, alkalies and water), and have good electrical insulating properties. V/ben properly pigmented, these coatings have good weatherability. Chlorinated rubber films plasticized with an Aroclor grip common structural materials in strong adhesive bonds. Addition of an Aroclor improves the flexibility and life of chlorinated rubber and plastic coatings. Tht formulations suggested in this bulletin are common in commercial practice. They are given as a starting point or guide in developing formulations that expand the outstanding qualities of these compounds. "ArsrJor: Monsanto Trsdemirk. Re*. U.S. Pit.

Arocior 2565--a 75:25 mixture (biphenyl to terphenyl) with 65 per cent chlorination. The physical properties of the Arocior plasticizers vary gradually with ihe degree of chlorination.. At low percentages of chlorine, such as Arocior 1221 and 1232, the compounds are clear and very.fluid. At 42 per cent they resemble vegetable oil; at 48 per cent they thicken slightly and look more like a medium-grade mineral oil. At 54 per cent chlorine, the compounds are quite viscous; if a bottle containing them is turned upsfd; down, the bubble rises slowly to the top. At higher percentages, the biphenyls become gumlike, and a fingerprint on the surface lasts several days. Then at 68 per cent chlorine, the. range is complete; Arocior 1268 is a white powder. The terphenyls (Arocior 5442 and 5460) are both yellowish solids.- The gradual change in physical properties often allows a processor to select a plasticizer particularly suited for his operation. For example, if he wants, to dry mix the plasticizer, Arocior 1268 could be used. It melts at higher processing temperature and can act as a solvent-plasticizer. -3- .

Some of their advantages are listed below: Adhesion Unplasticizcd chlorinated rubber films have very poor adhesion. The lacquer film containing Aroclor 5460 gave good adhesion to aluminum, bare steel, primed steel, galvanized iron and "Transite" surfaces. Othe* commercial resins, particularly oiLmodified alkyd resins, gave better adhesion to glass, tin, copper, sealed wood and cellophane. . The lacquer films plasticized with Arodor 1254 or 1260 gave good adhesion to `Transite," cellophane, gal vanized iron and primed steel surfaces. Some of the other commercial plasticizers tested in similar films gave better adhesion to aluminum, tin, bare steel, copper and scaled wopd surfaces. Though compounds with an Arodor alone possess pronounced adhesive qualities, belter adhesion to all of the surfaces results if mixtures of Arodor or varied contents are used. Resistance to Aqueous Solutions Chlorinated rubber films with Arodor 1254 or 1260 (plasticizers) and Arodor 5460 (resin) show satisfac tory 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 were produced with Arodor 5460 in ratios of 5:10 and 10:10 (/4rodor:"Parlon") than with other commercial resins in similar mixtures. Likewise, softer films result from Arodor 1254 or 1260 in ratios of 2:10 and 5:10 (Arodor:"PaT)on") than with other commercial plasticizers at these concentrations. From these tests compounds with Arodor are shown to have strong plasticizing action on chlorinated rubber. Cold-Check Resistance Arodor 5460 is superior to phenol formaldehyde resins in cold-check resistance imparted to chlorinated rubber films, but not as good as alkyds modified with long oil. Arodor 1260 used as a plasticizer proved somewhat better than Arodor 1254. Weather Resistance Pigmented chlorinated rubber finishes containing Arodor have consistently withstood outdoor weather tests, but unpigmented finishes do not stand up well regardless of the resin or plasticizer used. Poor resistance to ultraviolet light is also a weakness of chlorinated rubber, Most pigments (except ultra marine blue) are usable with ``ParIon" and are recommended if the coating is to be subjected to outdoor weather or ultraviolet light. However, pigment protection varies considerably. 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 containing Arodor 5460, 1254 and 1260 have shown satisfac tory sanding and polishing characteristics. - 7- MONS 074319 WATER_PCB-SD0000017777 Applications Alkaline-Resistant Coatings ' Products containing Arnclor and chlorinated rubber are highly resistant to alkalies and moisture.

Formula I showed good resistance to 10 per cent hydrochloric acid and S per cent sodium hydroxide solutions. Formula 2 gave excellent outdoor protection to metal surfaces on plants manufacturing acids. Formula 3 performed well on -exteriors of plants producing alkali. Formula 4 had excellent resistance to acids, alkalis and salt solutions. It also showed good adhesion to glass and other surfaces. Formula 5 proved good for resistance to warm, soapy water. Note: No finishes with Aroclor or chlorinated rubber are recommended for con tinuous exposure at temperatures above 140 F. Marina Finishes The marine industry makes great use of chlorinated rubber coatings plasticized with Aroclor to protect wood and metal on boats, barges and other marine equipment. They possess good resistance to salt water and their hard finish deters algae and other marine growth. A suggested formula for & white marine paint is given in Table VIII. Table VIII.

The Hercules Powder Company reports that preferred water phases for such paints art either a 1 per cent distilled water solution of "Aerosol OT" or a 4 per cent distilied-water solution of sodium oleate. A lacquer-to-water ratio of 2.5 to 1 (by weight) is suggested for the completr emulsion. " Parion" of any viscosity may be used. A typical paint phase for such an emulsion paint is given in Table IX.

In general, this type of coating is restricted by odor and taste. Unpigmented fin ishes seem suitable for certain fabrics used indoors, but not for exposure to high temperatures or direct sunlight 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 resistance of these plastics is an added dividend in the electrical field. Printing Inks Printing inks requiring a fast drying time and chemical resistance are often based on chlorinated rubber compositions plasticised with an Arocior. These inks are especially useful on soap wrappers and boxes, bottle labels and many other commodities because of their alkali resistance. -10 M0NS 074322 WATER_PCB-SD0000017780 Other Resins and Plasticizers Compatible With Chlorinated Rubber The resins and Monsanto plasticizers given in Tables XI and XI] are compatible with chlorinated rubber, but none gives the over-all desired qualities attained by using an Aroclor.

If the materials are heated to volatilization, ventilation should be provided to prevent inhalation of vapors. This is true of other major components of the formulation as well as the Arodor compounds. ' Repeated or prolonged skin contact should be avoided although there are few instances of skin irritation. Human patch tests with finished products containing Aroclor compounds have shown no irritation. Mon santo will furnish information on specific Arodor compounds upon request.
