Exceptional Technology in
Electroless Gold, Electroless
Nickel and More!

Auruna
Gold Processes
–
are available for various
requirements related to
color, hardness,
or purity.
|
|
AuBel
Electroless Gold
– most likely the
widest used electroless gold in the
world, this
process has been widely used in North
America
for more than 16 years. It is the most stable
electroless
gold chemistry known.
|
|
Platinodes
– the most sophisticated platinized
titanium
anodes available. Typical anodes are
either platinum-plated
(leaving micro-pores) or clad (leaving
micro-cracks). With the
aggressive nature of gold or rhodium
plating working
to shorten the
anode’s life. These anodes are plated using
a unique molten platinum
method – thus avoiding cracks
and pores and extending service life.
These anodes
are available in a combination of
mesh sizes, platinum
thicknesses, and single or double
sided coatings.

Non Mist-L Plating Anti-mist Additive is Uyemura’s newest
product development for metal finishers. Non Mist L is an anti-mist
additive for chromium platers that is EPA-compliant. This new anti-mist
additive forms a strong foam blanket that reduces the bath’s surface
tension, preventing the migration of dangerous mists. Non Mist L also
conserves plating solutions by minimizing evaporative losses and
drag-out. Chromic acid concentrations in the plating bath are kept
low and so is waste treatment.
Non Mist L plating anti-mist additive is highly effective in small amounts,
and has no negative effects on plating. It has desirable break-down
characteristics and won’t produce excessive foam. It is an excellent
product for improving shop environmental conditions and protecting
workers and equipment from chromium mist pollution..

Miralloy
– About 20% of the world’s
population has a skin
reaction to nickel metal. The longer
this metal is in contact with the
person’s skin, the more likely
they are to experience a burn –
which
worsens as the contact continues.
The perfect alternative is
Miralloy – an electroplating alloy
combination of tin, copper, zinc.
It is available
in white or yellow versions (the latter
only as an
under plate for gold) and is used
world-wide for zippers, buttons,
bra clasps, etc. The white version
is the most common and is
referred to as “white
bronze”. This version doesn’t
tarnish
and stands up well to normal clothes
washing/drying. This
process is also available in a lead-free
white version – the
most commonly used variation plated in North America.
Miralloy also has
gained wide acceptance for plating
on electronic
connectors—as a replacement
for silver (the white version doesn’t
tarnish) and palladium (due to lower
cost). It is available in rack
or barrel versions.

Rhodium
TD – from the
developers of Rhodium J-1 and J-2,
the new TD version produces the whitest,
brightest, most reflective
rhodium plating available.

CL
Satin Nickel Plating –
one of the most versatile finishes ever
developed, this electroplating process
can produce parts consistently
in several different finish appearances.
By filtering one ingredient
and replacing it with a second, or
third, or various combinations,
the grain structure
is changed such that different matte nickel
appearances can be plated.
CL Satin Nickel plating has gained
wide acceptance in the automotive
and plumbing industries –
among other decorative usages. Uyemura
introduced this important
satin plating technology to the North
American market. Today, we are
the leading supplier of both satin nickel and electroless nickel processes.

CL Technologies' SN1 Tin-Nickel Process provides a bright,
durable finish with a distinctive reddish layer that's ideal for decorative
applications. Plating over bright nickel or satin nickel creates a
distinctively warm appearance.
Excellent bath stability for highest color consistency; excellent
throwing power, too, so it's applicable to rack and barrel plating.
No top-coating needed. Better corrosion protection than general
tin-cobalt alloy plated coatings!

Nickstar Black Nickel –
Nickstar – a decorative black nickel
technology that deposits a thin, and highly uniform over-coat of black
nickel-zinc alloy, preserving the substrate's brightness and
producing an exceptionally rich black nickel finish.
|
|
NBB
Electroless Nickel –
this process is bright and robust
despite
being free of lead and cadmium. It
is a mid-phos electroless nickel
process in the range of 6 to 8.
|
|
KTY
Electroless Nickel –
from the research labs of Uyemura-Japan,
this process
is the world’s first “heavy metal –free” electroless
nickel. Lead, cadmium and other
heavy metals traditionally used for adding brightness
and stability have been eliminated.

ANP Electroless Nickel Plating for Aluminum –
substantially
improves plating onto aluminum. Plating electroless nickel on aluminum
has been problematic and costly due to short bath life. A normal EN bath
can plate steel for six to eight MTOs (36 - 48 g/l nickel plated). Plating
onto aluminum reduces that bath life by about 50%. The typical failure
is poor adhesion of the nickel to the aluminum, resulting in blisters or
nickel peel when the aluminum is bent.
Technology developed to address this problem of short bath life used
an alkaline nickel strike after zincating and prior to the regular plating
bath. Drawbacks to that approach include extra tanks, process steps,
and control over an additional plating bath. Failures have also been
seen with nickel-to-nickel bonding.
A further application-specific problem is that strike baths always
deposit magnetic nickel, thereby limiting their use to applications
where magnetism is not a factor.
Uyemura’s electroless nickel plating for aluminum provides excellent
adhesion through at least six MTOs. The process does not employ a
strike and adds no additional steps compared to normal aluminum
preparation double zincating.
This important new development uses Uyemura’s lead and
cadmium-free electroless nickel product in concert with proprietary
cleaning, etching and zincating technologies.

Thru-Nic
– the highest throw electrolytic
nickel process available,
now used in many diverse industry
sectors
|
|
Niphos
– electrolytic nickel-phos systems
that can replace gold
plating for some electronic connectors
due to its exceptional
corrosion resistance. These processes
are available in reel-reel
(Niphos 965) and rack/barrel/vibratory
(Niphos 966) formulations.
|
|
Dialloy
– tin/zinc alloy process that
produces 80/20 or 70/30
alloys. Good distribution, weldability
and solderability; provides
excellent corrosion protection for
iron and iron alloys.
|
|
Eballoy
– available in black or white
versions, this tin-cobalt
alloy process can be used over Miralloy
or copper-plated parts.

Copkia
RIP Au-II – widely
used process for stripping gold from
plated parts, at room temperature.
The most widely used process at
refiners
and platers throughout North America.
