Cargo Tank Coating · Paint & Coating Systems
PPG / Sigma SigmaLine CTR Ethanol is a shipboard unit in the Paint & Coating Systems group, classified in the source as Cargo Tank Coating. It is normally installed applied to the specified hull, deck, tank or structural surface and stored as coating material in approved paint stores before use. Its primary duty is to protect steel or other substrates against corrosion, fouling, fire exposure or wear and to provide the required finish for the stated service. In service it interfaces with surface preparation system, primer/intermediate/topcoat scheme, substrate condition and the vessel's coating maintenance plan. Compared with neighboring entries in the same product family, this record is the exact PPG / Sigma SigmaLine CTR Ethanol variant; the model designation should be retained unchanged when matching onboard documentation and spares.
