PPG PHENGUARD® 985 marine tank lining

Phenolic epoxy tank lining for market-leading cargo resistance 

PPG Phenguard® 985 premium solvent-based tank lining provides high levels of resistance to a wide range of aggressive cargoes including gasoline, fuel oil and chemicals. Its patent pending formulation also withstands biofuels and vegetable oils containing fatty acids that require higher temperatures for storage and transportation without delamination or blistering.  

 It offers flexibility for shipyard applicators. It delivers a robust film designed to withstand over-application in complex and overlapping areas. With a high DFT allowance, it can be specified and applied in two or three layers while maintaining its enhanced performance characteristics. 

Increasing operational flexibility for tankers

Aggressive cargoes can have specific requirements that cause challenges for vessel operators. Higher temperatures may be needed for viscous cargoes during loading and discharge, and storage temperature ranges can be very narrow, with a maximum of 60°C/140°F. Exceeding these parameters can lead to decreased tank lining efficiency and increased maintenance and repair costs.  

Designed to accommodate longer periods of high temperatures for fatty acid distillates and similar cargoes, PPG Phenguard® 985 enables tank temperatures of 60°C/140°F during a voyage. If required, a loading or discharge temperature of up to 70°C/158°F can be allowed for ten days and can reach up to 75°C/167°F for two days.

Reducing application time

The unique formulation of PPG Phenguard® 985 allows shipyards to apply either two or three coats. For cargo oil tank specifications, a two-coat system of up to 160μm/6.3 mils is possible.  

Its higher thickness tolerance reduces the need for costly rework and additional dry dock time in case of over-application. In tests and in the field, application time can be reduced by up to 22% by using a two-coat solution. 

Improving health and safety

PPG is committed to the development of sustainable products and processes. Substances of concern may appear on watch lists, have usage restrictions, or require specialized hazard labeling.   

In the formulation of PPG Phenguard® 985, substances of concern have been reduced or removed without compromising performance. The use of crystalline silica has been minimized in the coating base and salicylic acid has been removed from the hardener.
