Hi-Kote® 1
A protective coating for titanium
alloy and corrosion resistant steel fasteners.
Hi-Kote
1 applied to all permanently installed fasteners on the Boeing C-17 results in:
-
Superior airframe corrosion
protection
-
Enhanced structural fatigue life
-
Reduced assembly cycle times
-
$2.2 MILLION SAVINGS PER
AIRCRAFT!!!
Hi-Kote
1 is a phenolic-based aluminum coating with excellent corrosion and high
temperature resistance (to 450° F). It
is a solvent based material that is applied by spraying and is then oven
cured to fully develop it's
properties. It has excellent resistance to fuel, hydraulic fluid
and solvents, and contains softeners to reduce the brittleness of the
coating and to impart it's excellent adhesive properties. The
corrosion protection is powered via chromated compounds that have
been long accepted as effective corrosion inhibitors.
Hi-Kote
1 is used as a protective coating on Titanium, Nickel based (Inco 718)
and Cres alloy (A-286, 300 series stainless) products, most of which are
externally threaded fasteners. Hi-Kote 1 facilitates the
installation of fasteners as it's durable surface prevents galling
during push in. It has also been successfully used on aluminum
rivets to provide primary sealing around the fastener and eliminate the
need for wet sealant.
Hi-Kote
1 is widely accepted as the leader in protective aluminum coatings for
aircraft fasteners, and conforms to the requirements of Hi-Shear
Specification 294.
