When it comes to the appearance of finishes, the automotive industry’s expect<strong>at</strong>ions are<br />
particularly high; parts processed to the GMW4205 specific<strong>at</strong>ion have an organic, corrosion<br />
resistant co<strong>at</strong>ing with a uniform, glossy-black color.<br />
GM Approvals for Atotech Processes<br />
Atotech’s processes have been approved to the General Motors<br />
specific<strong>at</strong>ions GMW4205 for black zinc nickel co<strong>at</strong>ings and GMW3044 for<br />
zinc co<strong>at</strong>ings.<br />
The GMW4205 specific<strong>at</strong>ion calls for a corrosion resistant black organic finish<br />
over an electrolytically applied zinc nickel or zinc iron alloy deposit. Typically<br />
used on small fasteners, the acid zinc nickel process Zinni 210 combined with<br />
passiv<strong>at</strong>e Unifix® NI 3-34 L and top co<strong>at</strong> Techdip Black WL2 meet the<br />
performance requirements of the GM specific<strong>at</strong>ion. GMW4205 requires no<br />
white corrosion <strong>at</strong> 48 h and no red corrosion <strong>at</strong> 480 h in salt spray testing.<br />
The GMW3044 covers the basic requirements for electropl<strong>at</strong>ed zinc applied to<br />
fasteners, clips, and small and medium-sized ferrous parts, such as castings<br />
and stampings. Atotech’s acid zinc process Zylite® 11-50 in combin<strong>at</strong>ion with<br />
the EcoTri® LT passiv<strong>at</strong>e, Corrosil® Plus 501 (BG) and Rogard Lube 200<br />
sealer achieves the stringent requirements of GMW3044 – 120 NSS hours to<br />
white corrosion, 360 NSS hours (depending on part specific<strong>at</strong>ion) to red<br />
corrosion.<br />

Atotech's zinc and zinc alloys<br />
electropl<strong>at</strong>ing program combines<br />
zinc with perfectly m<strong>at</strong>ched<br />
passiv<strong>at</strong>es and sealers. Optimized<br />
adhesion of passiv<strong>at</strong>es ensures white<br />
rust protection of the zinc co<strong>at</strong>ings.<br />
The final finish – the sealer –<br />
stabilizes the passiv<strong>at</strong>e layer<br />
underne<strong>at</strong>h and adjusts the<br />
Coefficient of Friction.<br />
The homolog<strong>at</strong>ion of products is an<br />
essential part of Atotech’s activities<br />
within the automotive industry. "We<br />
are active in all major automotive<br />
regions in the world and make sure<br />
th<strong>at</strong> our products are approved to<br />
present and future OEM<br />

Spoke screws pl<strong>at</strong>ed with <strong>Protolux®</strong> <strong>3000</strong> <strong>at</strong> <strong>Union</strong> <strong>Autoparts</strong> <strong>Manufacturing</strong> in Thailand<br />

Protolux ® <strong>3000</strong> <strong>at</strong> <strong>Union</strong> <strong>Autoparts</strong> <strong>Manufacturing</strong> Co.,<br />
Ltd.<br />
Cyanide-free alkaline zinc processes, like <strong>Protolux®</strong> <strong>3000</strong>, offer<br />
superior corrosion protection compared to acid zinc pl<strong>at</strong>ed layers<br />
and are already well established in the pl<strong>at</strong>ing industry.<br />
A few years ago, the electropl<strong>at</strong>ing company <strong>Union</strong> <strong>Autoparts</strong> <strong>Manufacturing</strong><br />
Co., Ltd. was looking for such an alkaline zinc process th<strong>at</strong> could fulfill all its<br />
requirements. This process had to be capable of pl<strong>at</strong>ing enough zinc inside a<br />
through hole (> 2 µm) so th<strong>at</strong> it still would be possible to apply the passiv<strong>at</strong>ion<br />
– without stripping the deposited zinc.<br />
<strong>Union</strong> <strong>Autoparts</strong> <strong>Manufacturing</strong> Co., Ltd. has been using Atotech's alkaline zinc<br />
process <strong>Protolux®</strong> <strong>3000</strong> for rack and barrel applic<strong>at</strong>ions for over five years.<br />
<strong>Protolux®</strong> <strong>3000</strong> fulfilled the company's expect<strong>at</strong>ions and met all the<br />
performance requirements of <strong>Union</strong> <strong>Autoparts</strong> <strong>Manufacturing</strong>. Spoke screws<br />
(length 15 mm, inner thread M3) can be pl<strong>at</strong>ed inside with co<strong>at</strong>ing thicknesses<br />
as specified (see fig. above).<br />
<strong>Protolux®</strong> <strong>3000</strong> is a p<strong>at</strong>ent-protected additive system approved by automotive<br />
manufacturers like Renault and Daimler and provides an outstanding thickness<br />
distribution – even on complex-shaped parts.<br />

Trivalent Blue Passiv<strong>at</strong>ion for High <strong>Corrosion</strong><br />
Protection<br />
Hydrogen embrittlement is still an important topic for the pl<strong>at</strong>ing<br />
industry, especially for high strength steel. OEMs ask for he<strong>at</strong><br />
tre<strong>at</strong>ments of 8 h <strong>at</strong> 210 °C, in order to avoid brittle fracture of pl<strong>at</strong>ed<br />
parts.<br />
An efficient process flow requires th<strong>at</strong> the he<strong>at</strong> tre<strong>at</strong>ment is applied after<br />
electropl<strong>at</strong>ing and the passiv<strong>at</strong>ion process – without any discolor<strong>at</strong>ion or<br />
loss of corrosion resistance.<br />
Atotech has developed Tridur® HT, a blue thin film passiv<strong>at</strong>ion suitable<br />
for cyanide-free alkaline and acid zinc surfaces, fulfilling these<br />
requirements. Tridur® HT provides the highest corrosion resistance<br />
performance against white corrosion (72 - 96 h, NSS ISO 9227), is<br />
temper<strong>at</strong>ure stable and passes 8 h <strong>at</strong> 210 °C without color change.<br />
The process allows zinc pl<strong>at</strong>ing and passiv<strong>at</strong>ion in one shot elimin<strong>at</strong>ing<br />
the baking step in-between. The bluish appearance will remain even<br />
after severe he<strong>at</strong> tre<strong>at</strong>ments.<br />
Tridur ® HT<br />
+ One component passiv<strong>at</strong>ion process<br />
+ Homogenous bright blue appearance on acid and<br />
cyanide-free alkaline zinc<br />
+ Excellent corrosion protection<br />
+ Suitable for rack and barrel applic<strong>at</strong>ions<br />
+ Extended lifetime in combin<strong>at</strong>ion with Tricotect® –<br />

<strong>New</strong> <strong>Corrosion</strong> Protection Competence Center<br />
in Trebur-Geinsheim, Germany<br />
On September 24-25, Atotech celebr<strong>at</strong>ed the Grand<br />
Opening of the new <strong>Corrosion</strong> Protection Competence<br />
Center in Trebur-Geinsheim, Germany.<br />
More than 200 guests – amongst them the mayor of Trebur Mr. Juergen<br />
Arnold, Atotech customers and represent<strong>at</strong>ives of the trade press – were<br />
welcomed by Reinhard Schneider, President of Atotech, Pablo Nieto Aliseda,<br />
Vice President General Metal Finishing and Gertjan van der Wal, Vice<br />
President Europe & Americas.<br />
Covering an area of 3,700 m 2 – the equivalent to half the size of a football field<br />
– the new center houses Atotech’s R&D competence of corrosion resistant<br />
co<strong>at</strong>ings and zinc flake technology. Trebur is only 35 kilometers away from the<br />
Rhine-Main metropolis Frankfurt City and has already been the center of all of<br />
Atotech’s R&D and product development activities for zinc flake co<strong>at</strong>ings.<br />
In 2008, a TechCenter for corrosion protection was opened, offering all kinds<br />
of product and reliability testing, qualific<strong>at</strong>ion runs and customer sampling for<br />
both our corrosion resistant co<strong>at</strong>ings and zinc flake technology.<br />
The expansion of the facilities in Trebur and the reloc<strong>at</strong>ion of the entire<br />
<strong>Corrosion</strong> Resistant Co<strong>at</strong>ings Business Technology Team, including R&D,<br />
Business and Product Management, cre<strong>at</strong>e a center of excellence for<br />
corrosion protection, which is unique in Europe and even worldwide.<br />

The opening event was divided into<br />
two main parts: a festive ribbon<br />
cutting ceremony followed by a<br />
guided tour of the facilities as well as<br />
a technical session presenting<br />
Atotech’s core values and l<strong>at</strong>est<br />
corrosion protection processes, with<br />
a focus on green technologies.<br />
Being one of the very few leading<br />
suppliers offering both<br />
electropl<strong>at</strong>ing processes and zinc<br />
flake co<strong>at</strong>ing for corrosion<br />
protection finishes, Atotech can<br />
now maximize synergies between<br />
the two Business Technology<br />
Teams and continue to develop<br />
voice-of-the-customer-based<br />
