Viscosity: Solid at ambient temperatures; viscosity depends on the grade and handling temperature.

Remarks: A dark brown residue left after coal tar is redistilled. Coal tar pitch normally constitutes 50-65% of the usual grades of coal tar. Used as a binder for carbon electrodes, as a base for paints and as a plasticizer for elastomers and polymers, extenders, saturants and impregnants. Also used in impregnation of fiber pipe for electrical conduits and drainage, foundry core compounds, briquetting coal, paving and roofing.

Pump Notes: Cast iron construction is satisfactory. Pump jacketing features are recommended to keep the product liquid especially at start up. The product may contain abrasives that would require use of abrasion resistant parts in the pump.
