HVLP

 
Uses high volume low pressure air injected into a stream of pain to atomize.
 
Advantages Limitations
Flexibility Transfer Efficiency
Improved T. E.  Flow Rate
Low Pressure Solids Content
Low Cost 
Low Maintenance
High Quality Finish
Can use small quantities
 
Benefits
Easy to use
Reduced cost to operate/maintain

Air Assisted Airless

 
A combination of air spray and airless.  Uses medium hydraulical pressure through an elliptical nozzle and "Horm Air" to atomize.
 
Advantages Limitations
Speed Of Application Medium Pressure
Improved T. E. Flexibility
Sprays Most Coatings Not for Small Quantities
Almost no air in spray pattern Must heat coating for higher solids
Very Good Finish Tip Plugging
Not for fine finish applications
 
Benefits
Low cost per square foot to apply higher mils
Coating costs are reduced on high volume coating applications

Airless

 
Uses high hydraulic pressure to force coating through a small elliptical shaped nozzle to atomize.
 
Advantages Limitations
Speed Of Application High pressure
Improved T. E. Flexibility
No Air In Spray Pattern Higher initial costs
Sprays most coatings Not for small quantities
Plugging tips
Must heat coating for high solids
Not for fine finish applications
 
Benefits
Low cost per square foot to apply higher mils
Coating costs are reduced on high volume coating applications

Electrostatic

 
Uses up to 80KV to apply opposite charge on coating from grounded part.  Coating is attracted to the part.
 
Advantages Limitations
Best Possible T. E. Higher initial cost
Speed of Application Does not work on non conductive substrates without prep applications
Works with all application equipment Requires additional training and maintenance
Costs Edges Requires special accessories to spray highly conductive coatings
 
Benefits
Lowest cost per square foot on any spray processes
Quality improvement
Can cause labor reductions
