In
2002, PPG introduced the first scratch resistant clear coat (CeramiClear™) to
the automotive marketplace. Since then, scratch resistant clear coats have
rapidly become the standard in the automotive industry.
PPG
leads the market in offering a variety of scratch resistant clear coat
technologies that not only meet the rigorous requirements of automotive
manufacturing facilities worldwide, but also help vehicles retain a
showroom-like finish for a longer period of time. The result: greater
satisfaction with consumers, as they enjoy the look of their vehicles for a
longer period of time.
CeramiClear™
®Clear coat
PPG's
CeramiClear™ ®clear coat was the first clear coat to use nanoparticle
technology to achieve a previously unattained level of scratch, mar, and etch
resistance. This patented technology creates a hard, silica-like surface that
provides superior resistance to damage caused by day-to-day use, car washes,
and environmental hazards such as acid rain and tree sap.
While
this technology is currently employed as a two-component liquid clear coat, PPG
is very close to commercializing a one-component version for use in automotive
assembly plants. Are applied as a final coating over a traditional clear coat,
and has an approximate thickness of 7.5 µ (0.5 Mil) this top layer also
contains the paint systems UV protection. On Mercedes -Benz models that have CeramiClear™
®paint there is a ‘C’ prefix to the three number paint codes. If the code
reads"C040" you have black nanotech paint

This
was the reasoning behind CeramiClear™ ® – [PPG Industries Inc (2004) ceramic clear coat is unmatched in
scratch, surface marring and acid-etching resistance as well as gloss
retention. Test results have shown that after a period of six months gloss
retention shows an 80% improvement and acid-etching resistance is 50% better
compared to that of a non-ceramic clear coat. They have also developed an
aftermarket refinishing clear coat to provide approximately the same level of
protection as the OEM ceramic clear coat.]
DuPont's
SupraShield™, PPG's Optech™ and CeramiClear™ ® Clear Coat are all binary clear coat compositions using ceramic particles
designed to offer long-term scratch resistance, gloss and durability and is
applied as a final coating over a traditional clear coat, CeramiClear™
® has an approximate thickness of 7.5 µ (0.5 Mil) this top layer
also contains the paint systems ultra violet (UV ) protection.
[After the CeramiClear™
® top coat is sprayed, the nano particles of Fumed
Silica (SiO2), which are synthetically engineered, migrate to the top 5 µ
(micron) (0.2 Mil) of the clear coat as it is curing.
If you remove this portion of the clear layer
of paint, the paint under it will be much softer and will not polish out or
react the same way the nano particle portion did or would] - Dr. David Ghodoussi
PPG CeramiClear™ ® Clear Coat now comes in two commercial versions: CeramiClear™,
a two-component clear coat, and Certech, a single component clear coat.
PPG Industries have also developed an
aftermarket refinishing clear coat to provide approximately the same level of
protection as the OEM CeramiClear™ ® Clear
Coat nanotechnology
paint.
PPG Industries Inc and Menzerna
collaborated in the formulation of an aftermarket abrasive polish specifically
for removing surface imperfections like scratches and paint defects for the CeramiClear™ ® Clear Coat.
PPG introduced an OEM version of CeramiClear™
®clear coat in 2003 for Mercedes-Benz. The refinish version of CeramiClear™ ®clear
coat, D8126 for use with the Global Refinish System, was released the following
year and won the Gold award at the International Grand Prix for Technical
Innovation in Europe in 2005, recognizing expertise and technical excellence in
the vehicle equipment sector.
Both versions of the refinish CeramiClear™
®clear coat, Deltron DC4125 and D8126, perform to the same
standards as the OEM finish. Both are unparalleled in scratch, mar and
acid-etch resistance and retention of gloss," said Randy Cremeans,
manager, collision segments, North America, for PPG Automotive Refinish. PPG's
technical team in Allison Park, Pennsylvania, specifically developed tougher
durability tests for OEM CeramiClear™, because no automotive coating had
achieved this level of mar resistance before.
DC4125 is designated for use with PPG's
DBC and DBU Refinish Systems, and it is designed for the repair of cars that
have a CeramiClear™ ® OEM finish. High-solids clear, it meets all current VOC
limits and is suitable for use in Southern California Districts. DC4125 is
formulated for use with DCH4126 CeramiClear™ ®Hardener. (Source SpecialChem)
It
is important to note that manufacturer-approved paint suppliers vary by country
as each country (and even province/state) has their own environmental laws that
collision centres must adhere to. For example in the UK, Standox, Spies Hecker,
and BASF are the approved paint suppliers for Mercedes-Benz collision centres;
in the US, it is PPG, BASF, and Standox. In Canada, only BASF and Standox are
the approved paint suppliers and you will find only one or the other at any
authorized Mercedes-Benz collision centre
Abrasive
Polishing
Working with PPG, BASF and
Mercedes Benz, Menzerna 2003 developed special polishes for use on PPG
CeramiClear™ Clear Coat for removing scratches, swirls and paint defects Beyond superior
abrasives, Menzerna has pioneered the development of polishes
designed specifically for the hard clear coats, like those used by General Motors on the Corvette
and PPG CeramiClear™ Clear Coat being used by Mercedes Benz. Super Intensive
and Nanotechnology Polish are currently used by Mercedes
- Benz in Germany on their production line
to remove swirls and over-spray incurred during the painting process.
A unique family of abrasives developed by Menzerna
allows these polishes to remove defects, even on brand new paint finishes, with
no loss of surface gloss and no micro-marring. The abrasives are just one
factor in the equation; lubricants, solvents, emulsion and their carrier system
will determine the actual functional ability of the polish
Super Intensive Polish (SIP), Power Finish (PO203S) and Nano Polish (FG4000) these
polishes contain nanotechnology ceramic micro
particle diminishing abrasives, that are milled as fine as 0.3 µ (micron) and /also
contain a higher abrasive content, 7% whereas the other polishes contain 3%
abrasives
Beyond
superior abrasives, Menzerna has pioneered the development of polishes designed
specifically for the hard clear coats, like those used by General Motors on the Corvette and PPG CeramiClear™ ® Clear Coat being
used by Ferrari and Mercedes- Benz.
Super Intensive and
Nanotechnology Polish are currently used by Mercedes - Benz in
Germany on their production line to remove swirls and over-spray incurred
during the painting process. Some OEM paint specification require a dense
(hard) clear coat paint- Audi, BMW, Nissan and VW and
others
Modern automotive
paint systems of whatever density pose unique challenges to the detailer, to
determine the correct polish/and pad combination, machine methodology. This
requires a ‘test panel’ to see how the selected polish set-up responses to the
paint, and wither it will remove the surface scratches
Select a ‘typical’ 18 x 18 – inch area -one that
represents the type of defects that you want to remove and starting with the
least abrasive polish and / pad combination and then proceed until the defects
are removed.
This is the polish
/ pad combination you’ll need to use. Selecting the correct pad / polish
combination for the vehicles paint / defects can take just as long as the paint
correction process
