Product Highlights

  • MarineLINE® 784 from Advanced Polymer Coatings, is the premier cargo tank coating system available for chemical and product carriers, and the only high-performance lining that withstands all IMO approved chemical cargoes.
  • MarineLINE® is generally recognized as safe (GRAS) for food-grade cargoes. MarineLINE® 784 coating complies with the FDA and all applicable food additive regulations.
  • More chemical resistance than stainless steel, phenolic epoxies, and zinc silicate coatings.
  • Superior resistance to acids, alkalis, and solvents; maximum versatility to carry CPPs, PFADs, Bio-Fuels, and Methanol.
  • Virtually non-permeable for assurance of product purity.
  • Superior bond strength and adhesion.
  • Very low VOC - 99 grams/L (0.80 lbs./gal.).
  • Excellent flex stressing.
  • Resistance to wear, abrasion and impact.
  • Thermal shock resistance -40°C to +150°C (-40°F to +302°F).

Key Performance Benefits

  • Shipowners generate increased profitability.
  • Faster, effective, more efficient cleaning due to non-absorption, low surface energy, and smooth surface.
  • Inspection of tank coating application and curing by MarineLINE® professionals.
  • Easy tank cleaning with fewer slops, and fast-drying.
  • Minor tank touch-up repairs are done easily.
  • ABS ISO 9001:2008 Certification.

Cargo Tank Coating ROI


This 5-year comparison of MarineLINE® versus Phenol Epoxy coatings shows the tremendous difference in Additional Return On Investment. Chart calculations are based on data accumulated from a number of tanker shipowners.

25,000 DWT Tanker, nine voyages per year @ $20,000 USD per day

  1. 3 less cleaning days per voyage than Phenol Epoxy (27 more sailing days)
  2. 50% less cleaning chemicals used
  3. 50% fewer slops
  4. MarineLINE® cargo tank coating is fully cured when leaving the shipyard, so additional income is earned as MarineLINE® can immediately carry all cargoes on the MarineLINE® resistance list.

Insurance Warranty Through Helvetia Insurance

We have joined forces with Helvetia Group, the Swiss-based insurer, to offer a specialized insurance program to warranty the application and performance of MarineLINE® cargo tank coatings.

This insurance program covers shipowners and operators on the MarineLINE® tank coating for a specified warranty period up to 5 years. With the Helvetia program, APC offers customers a true ‘turn-key’ solution for their cargo tank coating.

Patented Polymer Technology


The greater the distance between the cross-links, the greater the permeation causing chemical attack and absorption. Our patented polymer technology delivers:
  • Higher chemical resistance
  • Higher temperature resistance
  • Resistance to permeation (absorption)

Superior Technology

Taking care of your cargo tank coating with proper cleaning and regular maintenance can provide years of profitable service. Well maintained MarineLINE® tanks have been in service 10+ years, and are still performing well. For some tanks, minor coating repairs have been made using the MarineMEND Repair system.

Our fleet of 4 new tankers, all employing the latest technologies, represents the future of shipping. That includes the MarineLINE® cargo tank coating, with the best tank surface for easily switching cargoes.


Long Service Life Potential


The MarineLINE® cargo tank coating has been applied to hundreds of maritime chemical and product tankers, covering millions of square meters of surface.

Our coating withstands the stresses of twisting and bending in rough seas while resisting temperature extremes of the cold Baltic winters to the hot Middle East summers.

These unretouched photographs of tankers at various inspection intervals provide some insight into the performance of MarineLINE®.

Easy Cleaning

MarineLINE® 784 has an ultra-smooth, glossy, low energy surface that reduces venting time, uses less cleaning chemicals and less energy for cleaning equipment, and leads to faster turnaround.

A wide range of approved cleaning detergents and chemicals can be used to clean and prepare the coating for next cargoes allowing you to maintain the coating with minimal effort.

"A well maintained MarineLINE® coating, with its very smooth surface, helps NST gain a quick turnaround in port, and provides effective cleaning from the wide range of products that we transport."

A History of Performance

The MarineLINE® cargo tank coating has been applied to hundreds of maritime chemical and product tankers, covering millions of square meters of surface.

  • The majority of ships coated are over 8 years old with some over 15 years old.
  • MarineLINE® has been applied successfully in major shipyards around the world.
  • These tankers have carried thousands of different chemicals, including Acids, Caustics, Solvents, Inorganic Chemicals, and Edible Oils, with some tankers changing their chemical cargoes up to 85 voyages a year.
  • APC’s MarineLINE® coating withstands the stresses of twisting and bending in rough seas while resisting temperature extremes of the cold Baltic winters to the hot Middle East summers.
