Leaching Rate of Polychlorinated Biphenyls (PCBs) from Marine
Aroclor 1254 contains a chlorinated biphenyl mixture that is 54% chlorine by weight. Rushneck et al. documented that 22 congeners (or congener pairs, in the case of co-eluting compounds) occur in Aroclor 1254 at concentrations greater than 1% of the mixture mass.
AROCLOR Monsanto Resins and Plasticizers for Chlorinated Rubber
Resins and Plasticizers for Chlorinated Rubber Introduction Monsanto produces a series of chlorinated biphenyls and polyphenyls identified by the trademark Aroclor* for use as plasticizers and resins for chlorinated rubber base lacquers, varnishes and paints. These protective coatings are fire resistant, corrosion
Monsanto, PCBs, and the creation of a “world-wide ecological
By 1944, Monsanto was warning its salesmen about the dangers of Aroclor. In its Salesmen’s Manual, the company warned that “All chlorinated hydrocarbons have measurable degrees of toxicity to the animal organism. Aroclors are no exception.” They listed both topical and systemic symptoms as well as acute and subacute effects of exposure to PCBs.
PCBs in Marine Paint Chips: A Leachability Study
paint. This test paint was composed of 77 parts 20 cp chlorinated rubber, 96.5 parts titanium dioxide, 87.5 parts xylenes, and 77 parts hi-flash naphtha. The test paint was spiked with Aroclor 1254 at two concentrations—approximately 2% (4.6 parts) and 10% (23 parts) Aroclor

Polyester resins Aroclor 1260 (10-15%) Effective and economical Aroclor 1260 (10-20%) fire retardant. Increases strength of fiber-glass reinforced polyester resins. Polystyrene Aroclor 1221 (2%) Plasticizer. Chlorinated rubber Aroclor 1254 (5-10%) Enhances resistance, flame retardance, and improves electrical insulating properties.
- Is Aroclor 1254 a chlorinated rubber paint?
- Aroclor-containing marine paints, including chlorinated rubber paints, are no longer commercially available. Therefore, an Aroclor 1254-containing chlorinated rubber‐based white marine paint was formulated for this study based upon a 1960s-era Monsanto Technical Bulletin (Monsanto ca. 1960) that specifies the components for the coating.
- Is Monsanto a polychlorinated polyphenyl?
- As noted earlier, Monsanto's trade name for its line of polychlorinated polyphenyl products was Aroclor®. Readers will please note that there is no 'h' in Aroclor.
- What PCBs does Monsanto make?
- Monsanto manufactured a range of PCB products under the trade name “Aroclor,” among the most common being Aroclor 1242, Aroclor 1248, Aroclor 1254, Aroclor 1260, Aroclor 1262, and Aroclor 1268.
- Did Monsanto sell Aroclor?
- Monsanto's Aroclor products accounted for nearly all of the US production.
- Were Aroclor fluids industrial products?
- Aroclor fluids and other trade-named products were industrial products. Although some applications were mandated by industrial codes, building codes, military specifications, and other requirements, most were subject to free-market rules: PCBs were sold and used where the perceived cost-benefit ratio outweighed that of competing chemicals.
- Who makes Aroclor 1254 PCB?
- The work described herein focuses on the PCB formulation known as Aroclor 1254, manufactured by the USA-based Monsanto Industrial Chemical Company (Monsanto).
