Dear Reader of the Standox paintwork guideline,

We are pleased to present to you the new paintwork guideline for professional refi nishes of Daimler AG vehicles. This new version meets the standards we set today for compre-hensive repairs with Standox refi nish systems that meet the Mercedes-Benz requirements.

With regard to contents, we mainly limit ourselves to provide the infor-mation necessary to enable a paint shop to use the Standox product and refi nish processes, which are requi-red for the repair of Mercedes-Benz vehicles under all quality-relevant warranty aspects.

We specially go into details of Mercedes-Benz refi nish systems for three-stage base coat colors, the so-called Bright colors and descri-be the steps necessary to refi nish Magno colors with matt clear coat. Special aspects of refi nishes on aluminum substrates and on carbon fi ber substrates (carbon fi ber

fi ber composite material CFRP) are treated separately. Mercedes-Benz off ers fair-value refi nish systems to its body shops for older vehicles with expired new-car warranty and for cars from other manufacturers. In this guideline, we describe only the wet-on-wet refi nish systems for metal and plastic substrates.

For any general product-specifi c and application information, data sheets and general notes on the application of Standox products please refer to the Standox website www.Stan-dox.com and the country-specifi c websites that are available in many languages.

We would specially like to point out to you that all Technical Data Sheets, Material Safety Data Sheets and the always up-to-date online formula search tool StandoWin iQ can be found there.

Mercedes-Benz’s long-term product strategy is to use if possible on a global basis VOC-compliant refi nish systems for warranty refi nishes which meet the existing European VOC directives. Any locally deviating legal requirements are, of course, to be followed. Paint systems consisting of products of diff erent paint manufac-turers are to be avoided not least for product liability reasons.

1.General notes on refi nishingMercedes-Benz defi nes a warranty refi nish system, which is required when special quality specifi cations must be fulfi lled. The usage of certain materials and work processes are spe-cifi ed therein. These specifi cations may apply to certain material properties but also to the existence of defi ned body shop equipment and its use by trained personnel. Besides the technological quality aspects of a warranty refi nish it is just as important for a car owner that color and gloss matches on all vehicle substrates. Today, blending the repair area into the adjacent original paintwork is a perfect and effi cient work method in view of the large number of ever more complicated colors. Panel repair is also possible for certain colors, however, this has to be decided indivi-dually in the body shop. Fair-value refi nishes for older vehicles are characterized by the use of alternative work processes limiting the time needed for the repair and are therefore less expensive. Limitations in the fi nish of the paint system are accepted in this case.

1.1. Mercedes-Benz internal informa-tion systemsWhen we visit body shops and hold trai-nings, we realize repeatedly that the internal information systems of Mercedes-Benz are not used intensively. Important sources providing the latest data for daily work remain concea-led.

We want to encourage you to use the follo-wing systems after login to the Mercedes-Benz XENTRY system as they provide fundamental information on professional vehicle repair. Groups 40, 97 and 98, in particular, are directed to topics that concern the paint shop. WIS, ASRA and diff erent Service Information will make your work easier. Good knowledge in how to use this electronic service literature is a prerequisite for participation in future paintwork training modules off ered by Merce-des-Benz Global Training.

1.2. Safety and environmental regu-lations in the workshop areaUnfortunately, we still realize today that wor-king and environmental conditions prescribed by law are not consistently followed. Informati-on is provided in the abovementioned systems and explicitly want to make you aware of the regulations that you need to comply with. It concerns your health and it is a proof of quali-ty work when regulations are complied with.The Standox safety video and tips for health and safety deal with all the important regula-tions and instructions and are a good basis to train your staff in this important subject area. Please get in direct touch with your Standox contact.

2. Substrate pretreatmentGood and thorough pretreatment is better than rework afterwards – this is essential for a perfect refi nish. No insurance company or other sponsor accepts the costs incurring for corrections during the refi nish or even redoing the paint job. This makes any damage calcula-tion incorrect and reduces the productivity of the company as a whole.

Professional substrate pretreatment is an essential part of all refi nishes and may not be regarded as a minor work. Considering the substrates currently used in Mercedes-Benz models, this work meets additional quality and safety requirements and must be carried out.

In accordance with the requirements of Mercedes-Benz which are based on the current quality of our refi nish materials, we re-commend dry sanding only. Professional san-ding equipment with effi cient dust extraction and sanding paper of diff erent grains suited for the respective substrates help to achieve a perfect surface fi nish. This creates a substrate that is optimally pretreated for the following base coat and clear coat application.For information on manufacturers of abrasives and random orbital sanders including dust ex-traction systems, please refer to your Standox consultant.

6

2.1. Metal with special focus on alu-minumIn the case of warranty refi nishes, it is absolu-tely mandatory to sand through to bare metal. Composite constructions of today’s modern Mercedes-Benz vehicles forces the body shop to have separate aluminum workplaces. All the working equipment and materials needed for aluminum substrates may only be used in this area to avoid contact corrosion. Dust from sanding must be discharged separately to rule out aluminum dust explosions.

2.2. Plastic with special focus on fi berStandard plastic substrates are pretreated with a pad soaked in cleaning agent. Furthermore, we recommend to heat untreated plastic subst-rates to avoid any adhesion problems.Damaged old paintwork, e.g. on bumpers can be dry sanded with P400. Small scratches in the surface can be levelled with putty.When treating carbon substrates by sanding and thereby removing carbon fi bers from CFRP components, a separate workplace with effi cient particle extraction is required. Visible carbon must be treated particularly carefully as every damage to the carbon fi ber structure is irreversible and the part has to be replaced.

3. Standox product list for warranty refi nishes and goodwill refi nishes, for Mercedes Benz-specifi c refi nish systems as well as all-important Standox products generally appro-ved for fair-value repairs on Merce-des Benz passenger carMercedes-Benz prefers a clearly defi ned paint system for these repairs, which fulfi lls internal quality specifi cations, but also considers local legal VOC requirements. We have therefore agreed to limit the confusingly high number of possible high-quality paint systems to those, most recently approved product developments in the respective paint systems This does mean that products and paint sys-tems approved in the past are still supported.

Note: In general, Standox EP-Primer Surfacer U7200 is still approved for warranty and goodwill refi nishes, however, we decided to refer only to the highly pro-ductive three-stage product system with 2K Wash Primer and 2K PUR Surfacer in the current version of the paintwork guideline. From our experience, today’s corrosion damages are very small defects which can be repaired very well with Standox Etching-Adhesion-Primer U3100 (also available in a 2K aerosol version). The original standard prescribing the use of Standox EP-Primer Surfacer U7200 for corrosion damage is no longer valid from today’s perspective of the quality of Mercedes-Benz cars. Products and refi nish systems of the past continue to be supported, of course.

4.1. Painting the body flange in the glazing area with Standox EP Primer Surfacer U7200

Individualization of vehicles‘ exteriors by using extraordinary eff ects and / or colors is advancing. Mercedes-Benz off ers with the so-called Bright colors, Designo and Magno colors a wide variety of these spe-cial valuable fi nishes. The particularities are described in the respective paint systems.Carbon substrates as well as the special substrate visible carbon are often used for

AMG cars and are therefore also menti-oned. First of all, however, we would like to point out to you a safety-relevant process when it comes to painting the body fl ange in the glazing area. Here, Standox EP-Pri-mer Surfacer U7200 or Standox VOC-Non-stop Primer Surfacer U7580 can be used. Bonding of components on other substrates is not allowed.

These are three-stage colors consisting of a base coat ground color, base coat eff ect color and clear coat. Examples are Hyazinth red, Diamond white, Solarbe-am, Le Mans red or Cadmium red for the Smart. The whole color impression is mainly determined by the even fi lm thickness of the eff ect color, so that it is here very important to apply the eff ect color very accurately and in an even fi lm.

4.3 Magno colors

Customers who like matt fi nishes can order Mercedes-Benz colors from the Magno series. Here, instead of a „clear“ clear coat, a very matt clear coat is applied. Some special details need to be observed and as these are very high-grade vehicles of the Designo Exclusive Series from AMG Performance Studio, only trained painters are to carry out this type of repair job. Examples for Magno colors of the current color program are:

• Alanit grey 0044 (designo),• Cashmere white 0049 (designo) and• Cerussite grey 0281 (designo)• Selenit grey 7297

The degree of gloss of the current Magno colors is set to 23 (+-7) gloss units at a 60° angle.Dust inclusions in matt fi nishes cannot be polished out. Polishing will even the diff use surface and thereby, the degree of gloss will increase.

The care of matt clear coat surfaces and approved care products are described in detail in the Service Information in WIS.

a new layer of clear coat!

Chrome eff ects on vehicle substrates are normally produced by electrochemical processes. For the fi rst time, Mercedes has succeeded in achieving a comparable eff ect with waterborne base coat with the Mercedes-Benz Alubeam base coat.

4.5.1. Carbon‐Fiber reinforced plastics; coated

CFRP is made of fi lament yarn embedded in resin. The material is characterized by extremely high stability at comparably low density and thus weight. This is also the main reason why it is used for automotive engineering.

Today, production processes are so advan-ced that they help to avoid the formerly dreaded voids in the surface. Only these perfect parts are used today in the Aftersa-les component range of Mercedes-Benz.

The main challenge when coating CFRP is to avoid that the texture noticeably shines through the clear coat.

The use of the following products and care-ful method of working guarantees a perfect surface fi nish for color-coated CFRP, and also for visible carbon.

6. Color identifi cation6.1 Color code on model plate

We strongly recommend to identify the best color match (or variant) before starting with the actual repair work. This is the only way to make sure that all mixing colors needed to mix the right formula are available.

For the younger model series, the Merce-des-Benz color code can be found on the model plate which is located on the B pillar at the driver’s side.

For production reasons, there are two codes for the Smart: one for the tridion cell and one for the plastic body panels.

6.2 Mixing formula

To verify the formula found, we recommend spraying a sample panel. To identify the right mixing formula, please use the Standowin IQ as most up-to-date online color search tool, Standowin DVD, Genius IQ / Genius spectrophotometer or the Standox Color Documenta-tion

The eff ort needed for this is covered by the Mercedes-Benz repair times.
