Problem: Foaming caused by air in coating

 

Solutions:

Pump Sucks Air Into Circulation System Because Coating Level In Reservoir Or Coating Pan Is Too Low

• Maintain levels so pump intake is always submerged.

Air Is Sucked Into Recirculation System Through Leaks In Pump Seals Or Piping

• Repair leaks, tighten clamps and fittings, and check hoses for holes.

Pump Is Running Too Fast Or At Too High A Pressure

• Set pump for correct speed and pressure.
• Verify that the pump being used is appropriate. Nicoat recommends a diaphragm pump.

Pipe/Hose Ends Too Short - Splashing Occurs On Return To Drum/Container

• Prevent freefall by configuring return loop so that outflow (pipe or hose) is submerged into the drum or container.

Coating Is Too Thick

• Reduce coating viscosity by adding water or raising the temperature. Make sure coating is not full of foam or the viscosity will be inaccurate.

Excessive Foaming Still Appears

• If all other causes have been addressed, consult Nicoat.
