suspected that the improvement may have been the result
of the finishing line upgrades alone and chose to return
to TGIC powder coatings. Transfer efficiency dropped and
gloss rating variations returned. The company has since
used TGIC-free powder coatings
exclusively for this application.
• A producer of structural steel
components moved to TGIC-free
powder coatings after an OSHA
inspection of the company's
existing powder coatings line
required line employees to be
fitted with expensive protective-
air-supplied suits. After the
switch, employees needed to wear
only dust masks, saving thousands
of dollars. As an added benefit,
the manufacturer found that the
new coatings were easier to apply
and provided better transfer effi-

efficiency comparisons.
