MarineLine® Enhanced

A Coating with Superior Chemical Resistance, with High Impact Resistance, and Elongation Virtually Equal to Steel, for Chemical and Product Tankers

MarineLine 784

What is MarineLine®?

The MarineLine® Enhanced cargo tank coating has been engineered to provide both high chemical resistance, and high impact resistance, as requested by shipowners to withstand mechanical damages that may be incurred during cleaning, repairs, etc. Advanced Polymer Coatings’ MarineLine® Enhanced is a tougher version of its previous coating system.

With this R&D breakthrough, several other features have also been realized, thus adding significantly to the overall performance of the coating. Key benefits of the enhanced formulation include:

  • Increased Impact Resistance more than 50% creating a tougher, more durable coating.
  • Increased Coating Elongation (flexibility) more than 100%, to virtually match the carbon steel cargo tank.
  • Reduced Surface Energy almost 60% for easier, faster tank cleaning.

Application Data

Note: The following application data is provided as a General Guide Only. Detailed instructions are provided for the MarineLine® Enhanced coating system. Only full detailed application specifications are to be used during actual application.

Note: MarineLine® Enhanced is shipped in a highly viscous state for heated plural spraying. For airless spraying, Toluene must be used for thinning.

Thinning

It is always necessary to thin MarineLine® coating, EXCEPT if using Heated Plural Spray equipment. The following thinning instructions should be followed.

VOC Content
MarineLine® Enhanced
as Supplied
Coating Thinned with
2% Toluene by Weight
Lbs/Gallon Grams/Liter Lbs/Gallon Grams/Liter
0.33 + 1% 42 + 1% 0.14 + 1% 61 + 1%

 

The applicator should make exact thinner adjustments based on the equipment used, and air and surface temperature.

Note: Add and mix solvent into Part ‘A’ prior to adding Catalyst Part ‘B’.

Surface Preparation

Steel: Grit blast to SSPC-SP10 Near White Profile 3 to 4 mils (75 to 100 microns)

Mixing Instructions

Material is supplied in two containers as a unit. Always mix a complete unit as supplied (do not split units).

  1. Thoroughly mix the contents of Part ‘A’ with additional solvent with a power agitator until uniform consistency and all solids have been put back into suspension.
  2. Slowly mix in the contents of Part ‘B’ Catalyst with previously mixed Part ‘A’.
  3. Thoroughly mix the two parts until a uniform consistency and color is achieved.

Clean Up Solvent

Acetone, Xylene or Toluene

Limitations

Apply when the air and surface temperatures are above 15°C (59°F). Relative humidity must be kept at 70% or lower. The substrate temperature should be at least 3°C (5°F) above the dew point and rising. For optimum application properties, bring material to 21-30°C (70-86°F) prior to mixing and application. Increased temperatures will result in shorter pot life.

Application

Airless spray equipment with a minimum 43:1 pump ratio @ 80-100 lbs. to achieve 2500-3000 psi tip pressure: Reverse-A-Clean tip .019 to .023, with a 3/8” fluid hose, and ¼” whip hose. This coating is a low VOC compliant material. If conditions require a viscosity adjustment, thin with Toluene.

Apply first coat to wet film thickness of 5-6 mils (125-150 microns). Allow to dry to touch approximately 10 to 16 hours depending on temperature and airflow. Apply second coat to wet film thickness of 5-6 mils (125-150 microns), total 10-12 mils average (250-300 microns average).

Inspection

After second coat has dried and will not move when pressed with a finger, the inspection can take place (spark testing, DFT) and repairs can be made prior to heat curing.

Cure Time and Temperature

In order to handle aggressive chemicals, MarineLine® has to be fully cured to avoid problems. The following curing method is used:

A forced hot air curing at 90°C (194°F) to 122°C (250°F) for minimum 6 hours. Electrically heated or gas combustion air only to be used.
Note: All temperatures are metal temperatures. See Full Specification for application of MarineLine® Enhanced coating.

Handling Precautions

Solvents and chemicals are contained in this product. Consult the Material Safety Data Sheet for details. Adequate safety and health precautions should be taken during handling, application and drying of this product. The material should be applied under local, state, and federal regulations and in accordance with OSHA and ANSI bulletins on safety requirements.

Packaging

Available as:
5 gallon kit with catalyst
1 gallon kit with catalyst

A History of Performance

MarineLine® Enhanced is based on APC’s MarineLine® cargo tank coating that has been applied to more than 700 maritime chemical and product tankers, covering over 10 million 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.
