When the pipeline structure is kept above ground and subject to UV impact, the Humidur® epoxy coating may discolor because of this effect. Acotec offers therefore an additional UV topcoat, Humidur® TC, to keep the color for esthetical reason. This additional layer gives no added value in terms of corrosion protection and is solely used to maintain the color of the coated pipeline. This topcoat is available in any RAL-color.
