Profit from GuardLine®

Generate a Strong Return on Investment (ROI)

This new coating provides a safe and effective tank lining system. This coating is based on an ambient cure (+25°C/+77°F), and is recommended for product/parcel tankers and barges carrying:

  • Bio-Fuels
  • Clean Petroleum Products (CPPs)
  • Vegetable and Edible Oils
  • PFADs
  • Dirty Petroleum Products (DPPs)
  • Wine

Key GuardLine® Performance Benefits and Product Highlights

Utilizes new eco-friendly formulation system with ultra-low VOCs.
  • Faster, easier, more efficient tank cleaning due to low surface energy smooth surface
  • Virtually non-permeable, steam cleanable, and field repairable
  • Minor tank touch-up repairs done easily
  • Higher elasticity giving greater toughness and durability for long service life
  • Superior bonding qualities
  • Greater corrosion resistance than Phenolic Epoxies and Zinc coatings
  • Resists acidified moisture (Sulphuric Acid) of wet inert gas systems, providing long-term coatings performance
  • Exceptional toughness and high impact resistance
  • Consistent product purity
  • Complies with all FDA regulations
  • Maximum versatility; product cycling
  • Ambient or low temperature forced air cure
  • Substantial operational savings over the life of the ship
  • Shipowners generate strong Return on Investment (ROI)
  • GuardLine® is offered at a cost comparable to Phenolic Epoxies

Determine which APC Cargo Tank Coating System is Best for Your Needs

GuardLine® (Ambient Cure +25°C/+77°F)

Provides product/parcel tanker owners who trade in the CPP, Bio-Fuels, Vegetable and Edible Oils, and DPP markets, with a coating that offers greater versatility and chemical resistance than any Phenolic Epoxy or Zinc coating on the market today and at a comparable cost. Combine this with the ease of application and cleaning and the owner can maximize return on investment in a short period of time. A lower cost solution, but not able to carry more aggressive chemicals.

MarineLine® (Forced Hot Air Heat Cure)

Outperforms stainless steel and all other coatings providing the highest chemical resistance available on the market today. Being heat cured in the shipyard enables MarineLine® coated tanks to carry aggressive cargoes immediately after leaving the shipyard without restrictions, allowing the ship owner to earn premium chartering rates from day one. A higher cost solution, but able to carry the widest range of chemical and product cargoes.

Over 700 ships coated with MarineLine®.


History of Performance

APC coatings and linings have been proven worldwide under the most arduous operating conditions. From resisting the most aggressive cargoes to handling hot cargoes in the sub-freezing arctic, MarineLine®-coated ships have withstood the tremendous stresses and extremes of changing cargoes almost on a weekly basis. Based on this experience, the development of GuardLine® represents a quantum leap in tank lining technology.
