The chart at le shows less than a 1% thermal
performance impact between an uncoated and E-Fin
coated coil when fi rst applied. A er 1000 hours of
salt spray tes ng the E-Fin coil s ll performs at 90+%
whereas the uncoated coils performance has dropped
below 60%. A clear indica on of how York’s E-Fin helps
retain the products performance in harsh condi ons.
With York’s E-Fin coil coa ngs customers can realize
extended products coil life and con nued performance
from the product: whereas other manufacturer’s
products with uncoated coils begin deteriora ng in both
coil surface area and performance within a short period
of  me.
York’s E-Fin meets these test standards
York’s E-Fin coil coa ngs are chemically resistant to the

ElectroFin is not intended for liquid to liquid (immersion) applica ons. Elevated temperatures can have an
adverse eff ect on the corrosion durability of ElectroFin, depending on the specifi c environment. This table is to
be used as a GUIDE for general reference. For specifi c corrosion resistance durability, please contact your York
representa ve to discuss your individual applica on.
Technical Performance
Electrocoa ng is the process by which a metallic work piece (coil)
is submerged in a paint / water bath where electricity is used to
deposit paint onto it.
York’s ElectroFin® E-Coat Process
Specifi ca ons
Coil will have a fl exible epoxy polymer e-coat uniformly applied to all coil
surface areas with no material bridging between fi ns. The coa ng process will
ensure complete coil encapsula on and a uniform dry fi lm thickness from 0.6
– 1.2 mils on all surface areas including fi n edges and meet 5B ra ng cross-
hatch adhesion per ASTM B3359-93. Corrosion durability will be confi rmed
through tes ng to no less than 5,000 hours salt spray resistance per ASTM
B117-90 using scribed aluminum test coupons.

Corrosion Resistance
In the electrocoa ng process, the coil acts in the
same way as a magnet. The coa ng molecules are
electrically a racted to the metallic coil surfaces,
meaning the en re coil is completely and uniformly
coated. The result is a fi nish which provides excellent
resistance to coastal marine (salt-air), industrial and
urban environments. When properly maintained,
you can expect York’s E-Fin coated coils to provide
protec on for years.
