Abstract
A process and composition for coating a pipe and a pipe support includes mixing a cellulose acetate, a plasticizer, and an oil together so as to form a solid mixture, heating the solid mixture so as to form a liquid state, covering an area of the joinder of the pipe and the pipe support with the liquid state, and drying the liquid state on the area of the joinder. An ethylene-based polymer stabilizer is added to the mixture of the cellulose acetate, the plasticizer and the oil. The oil migrates by gravity from the liquid state from the covered pipe into an area of contact between the pipe and the pipe support. The liquid state is applied around the outer diameter of the pipe and over the outer surface of the pipe support underlying the outer diameter of the pipe.

A process for coating a pipe and a pipe support, the process comprising:
- mixing a cellulose acetate, a plasticizer and an oil together so as to form a solid mixture, the plasticizer being an epoxidized linseed oil, the oil being a canola oil and an epoxidized soybean oil;
- adding an ethylene-based polymer stabilizer during the step of mixing, the ethylene-based polymer stabilizer being a polytheylene that carries a pigment;
- heating the solid mixture so as to form a liquid state;
- covering an area of a joinder of the pipe and the pipe support with the liquid state;
- and
- drying the liquid state on the joinder.
