Except as noted, costs are based on those existing in the industry in 

 1964, and relate to continuous operations on relatively large flat 

 panels of fin stock prior to fabrication. Add $0.01- 0.03 per sq, 

 ft. for cleaning. 



Roughly equivalent to anodizing, chemical cost $0.50 - 0.75 per sq. 

 ft. per mil thickness; however, only 2/10 - 3/10 mil coating thickness 

 needed. Chemplate Corp. proposes test on actual fin stock as basis 

 for quotation. 



Primarily applicable to copper tubing prior to assembling fins. Brush 

 plating after final assembly is possible for areas left unplated for 

 soldering. 



Electrodeposited enamel on assembled test coil quoted at $0.01 per 

 perimeter inch, amounting to $25.75, or approximately 50% of coil cost, 

 per coil. 



Quotation basis; minimum set-up charge $70.00 per coil.
