The chart at le shows less than a 1% thermal
performance impact between an uncoated and E-Fin
coated coil when rst applied. Aer 1000 hours of
salt spray tesng the E-Fin coil sll performs at 90+%
whereas the uncoated coils performance has dropped
below 60%. A clear indicaon of how York’s E-Fin helps
retain the products performance in harsh condions.
With York’s E-Fin coil coangs customers can realize
extended products coil life and connued performance
from the product: whereas other manufacturer’s
products with uncoated coils begin deteriorang in both
coil surface area and performance within a short period
of me.
York’s E-Fin meets these test standards

ElectroFin is not intended for liquid to liquid (immersion) applicaons. Elevated temperatures can have an
adverse eect on the corrosion durability of ElectroFin, depending on the specic environment. This table is to
be used as a GUIDE for general reference. For specic corrosion resistance durability, please contact your York
representave to discuss your individual applicaon.
Technical Performance
Electrocoang 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
Specicaons
Coil will have a exible epoxy polymer e-coat uniformly applied to all coil
surface areas with no material bridging between ns. The coang process will
ensure complete coil encapsulaon and a uniform dry lm thickness from 0.6
– 1.2 mils on all surface areas including n edges and meet 5B rang cross-
hatch adhesion per ASTM B3359-93. Corrosion durability will be conrmed
through tesng to no less than 5,000 hours salt spray resistance per ASTM
B117-90 using scribed aluminum test coupons.

Corrosion Resistance
In the electrocoang process, the coil acts in the
same way as a magnet. The coang molecules are
electrically aracted to the metallic coil surfaces,
meaning the enre coil is completely and uniformly
coated. The result is a 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
protecon for years.
