AQUAGUARDTM FOR SHIPPING LINES

Valspar Aquaguard zinc-free waterborne coating outperforms standard solvent-based coatings in corrosion performance. On containers coated with Valspar Aquaguard, the onset of corrosion from container damage is reduced at least 60%* compared to zinc-based coatings. This enables containers to stay in service longer with fewer repairs while also helping shipping lines drive sustainability efforts. Valspar Aquaguard also eliminates the potential of zinc leaching into local water supplies when storing containers, reducing costs associated with capturing water runoff.

*Based on 710 Hour Salt Spray Test Results


Corrosion Protection

Fire requires three elements to ignite: the same is true to ignite the corrosion process.

 

Valspar Aquaguard dramatically outperformed standard solvent-based coatings with zinc in this 710 Hour Spray Test

On average the corrosion is reduced by at least 60% on tested areas

Zinc Coatings

Corrosion resistance of this zinc rich primer, epoxy mid coat and acrylic topcoat industry control. The corrosion cell, (Defined as the area below the coating substrate interface) was measured at 310 micron wide and a pit depth of 95 micron.

The depth of pit shows just how far into the container the corrosion was able to reach.

 

Valspar Aquaguard

The corrosion cell was reduced by approximately 60% compared to the Panel 1 control.

There is noticeably less red rust inside the scribe.

 

Reducing Solvents and Zinc

Reduced solvents and zinc lessen the weight of a container AND reduce odor.

 

Elements of Fire

DOING ANY OF THE FOLLOWING STOPS A FIRE:

  • Spraying water removes the heat
  • Spraying CO2 removes the oxygen
  • Isolate the fire allowing the fuel to be used up

 

Elements of Corrosion

DOING ANY OF THE FOLLOWING STOPS CORROSION:

  • Stop water from going to the surface
  • Stop oxygen from moving to the metal
  • Remove ion potential

Zinc Coating Systems

SOLVENT-BORNE / ZINC BASED COATINGS:

  • To accomplish the removal, the Zinc "sacrifices" itself, degrading, to slow the rusting process
  • The "sacrifice" produces a larger rust area than waterborne solutions

Valspar Aquaguard Solution

VALSPAR AQUAGUARD WATERBORNE COATINGS:

  • To stop corrosion, zinc based coatings remove the Ion potential
  • Prevents water from reaching the surface to mix with Oxygen
  • Prevents Oxygen from reaching the metal
  • Performs without "sacrificing" itself, holding corrosion to smaller area
