What is coal tar coating?

Coal tar enamel (CTE) is a polymer-based coating produced from the plasticization of coal tar pitch, coal, and distillates. Over the years, this coating has been used in conjunction with a primer, a fiber glass or mineral felt reinforcement, and an outer wrap [3]. A typical pipe specification is AWWA C203.

Does epoxy stick to tar?

When to use a primer on coal tar?

Improper mixing may result in product failure. A primer is not necessary, however, if the substrate is excessively porous, a suitable primer can be used to help eliminate any surface defects resulting from air release from the substrate. The mixed material can be applied by brush or roller.

What should the temperature be for coal tar to crystallize?

The fluctuation of temperatures can make the product crystallize. It is stable at room temperature or at least 5°F above dew point. The environmental conditions affect the drying time of the product.
