Examples of mechanical tube applications.

ASTM B117 Salt Fog – 912 Hours UV versus Water-based at 0.3 Mils
Dry Film Thickness.

Embracing a Sustainable
Manufacturing Process
UV is inherently cleaner that water-based coatings with no VOC
or HAPs. Plus, eliminating the handling / exposure of flammable
water-based coating on the plant floor makes for a safer and
cleaner overall coating operation.
In the example below, the water-based coating contains
1.86 pounds of VOCs per gallon, where UV contains zero pounds
of VOCs.

Example: Yearly VOC savings of 108,628 lbs
with UV Coatings
