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.

   
Miralloy (Trialloy) – 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 used world-wide for zippers, buttons, bra clasps, and is sometimes
referred to as “white bronze”. It 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 (it is tarnish-free) and as a replacement for palladium (due to lower cost). It is available in rack
or barrel versions.

SN1 Tin-nickel Plating 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; no top-coating needed. Corrosion protection is superior to general tin-cobalt plating. SN1 has excellent bath stability for highest color consistency, and excellent throwing power, too, so it's applicable to rack and barrel plating.

   
Umicore Electrolytic Palladium 457 – is suitable for decorative
and electronic applications. Slightly alkaline (7.7 pH) palladium electrolyte
produces high-gloss, low-porosity coatings that are bendable and crack-free,
up to 3 μm.  Excellent corrosion resistance; stable electrolyte has a wide
operating range of current density.  Compatible with rack and barrel
application; ideal for wire connectors, wire leads, automotive engine
components and decorative parts, cabinet hardware, military equipment,
printed circuit boards
.
   

Non Mist-L Plating Anti-mist Additive is an anti-mist
additive for chromium platers that is EPA-compliant. This 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.

   

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.

   

Nickstar Black NickelNickstar – 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.

   

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.

   

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.

   

Copkia Rip Palladium Additive – this economical step allows
the above process to easily convert to a palladium stripper.

   

Auruna, Platinode, TD, J-1, J-2, Niphos, Dialloy, Electrolytic Palladium 457, Miralloy and Trialloy are trademarked products of Umicore-GT; all other products
listed are from Uyemura.
