Since its development in 2008, the enhanced plastisol coating (EPC), being a heat-applied material, has faced limitations in application to large substrates such as steel utility poles, pipelines, tanks, structural members, cabling, and rebar. The dimensions and weight of substrates such as those listed not only present challenges in handling, but the cost of heating those substrates to the application temperature of 360°F (182°C) was prohibitive. With advancements in induction technologies and the adaptability of the technology, induction can be used in the application of the EPC, both in the factory and in the field. A demonstration of induction technology to apply the EPC is discussed in the paper.

Infrared heating also facilitates the application of the EPC to large and/or complex shapes. The resins suspended in the EPC react well to infrared. An infrared clamshell can be used for the EPC application to a steel utility pole.
