PPG’s Aerocron
Electrocoat Primer
Meets Aerospace
Specification 3144 for
Aircraft Applications
PPG Industries’ aerospace coatings group
has qualified AEROCRON electrocoat
primer to SAE International’s Aerospace
Material Specification 3144 for anodic
electrodeposition primer for aircraft applications. Qualifying Aerocron primer
to the aerospace industry standard provides airframe manufacturers and subcontractors with third-party verification
of its performance characteristics and
attributes, according to Duane Utter,
PPG global coatings segment manager,
military coatings and classified products.
Four variations of the PPG chromate-free
primer have been qualified to AMS 3144
in order to meet specific customer or regional requirements.. Primer provides
corrosion resistance to metal parts and is
typically applied by spraying. In the electrocoating, or electrodeposition, process,
metal parts are dipped into an electrically
charged tank of Aerocron primer.
Sink or Swim 2014 Issue
Call for Papers
Please mark your calendars for the
Cleveland Coating’s Society Annual “Sink
or Swim” Technical Symposium commemorating 100 years of innovation being held June 3-4 2014 at the Cleveland
Airport Marriott.
Christopher Connor, CEO and chair-
man of The Sherwin-Williams Company
will be the keynote speaker. To comple-
ment the Technical Program this year the

Retrospectives to commemorate “A
Century of Innovation.” Two Technical
Short Courses will be offered, including
“Navigating the New Environmental/
Regulatory Landscape, 2014 and Beyond”
and “Statistical Design of Experiments
for Coatings Formulators.”

BASF and OEMs Develop
ASTM Test Standard for
Transportation Coatings
A collaborative 14-year effort involving BASF, automotive and aerospace
original equipment manufacturers
(OEMs), material suppliers and test
equipment manufacturers has resulted
in a new American Society for Testing
and Materials (ASTM) test standard for
transportation coatings.
The new method is 30 to 40 percent
faster than the previous test standard
used for many OEMs, and improves
the accuracy to nearly 100 percent in
predicting coating service life compared
to less than 50 percent with the previous standard. Industry implementation
of this new test can speed new product
development, and aid in the development
of better overall products for the coating
industry. This test can be used for automobiles, aircrafts, trucks and rail cars.
Officially named ASTM D7869-
13 Standard Practice for Xenon Arc
Exposure Test with Enhanced Light
and Water Exposure for Transportation
Coatings, the new test simulates physical
and environmental stresses that an exterior transportation coating is exposed to
in a subtropical climate. These stresses
include long water exposures, wet/dry cycling, and high dosages of solar radiation,
all of which have been shown to cause
severe coatings deterioration.
The new test conditions consist of a
primary test cycle and a sub-cycle. The
primary test includes two long water exposures and a single, long light exposure
with precise spectral match to daylight.
The sub-cycle consists of shorter alternating water and light exposures and is designed to simulate cyclic stresses such as
cracking and surface erosion.
These two cycles are designed to
replicate the common types of coatings failures driven by the interaction of
photo-oxidation during daylight and hydrolysis during water exposure. Together,
these failures can lead to gloss loss, color
change, adhesion, blistering and cracking.
BASF has been active in the ASTM
D-01 committee on accelerated weathering for many years, and began efforts
in test development in response to a customer issue. BASF brought key partners
together, developed the critical coating
formulas for testing, and conducted several important experiments in the physical test laboratories, which resulted in the
new test method.

American Coatings Conference to Kick Off with Keynote
Speaker Charles F. Kahle From PPG
The American Coatings Conference (ACC) will commence with a keynote presentation given by Charles F. Kahle, II, chief technology officer and vice president, Coatings
R&D at PPG Industries. Starting with a wide lens on the future, Dr. Kahle’s address
will explore the usual technology drivers that are shaping current coatings technology innovation, such as end-user requirements, broader sustainability demands and
critical environmental considerations. From this baseline, the address will explore
the dynamic changes driven by energy cost and availability, and how these changes
are shaping the future of coatings technology. From the price of oil and the need
for greater energy efficiency for our customers, to the role of shale gas and fracking
technology on raw material supplies, to bio-based raw materials and new pathways
for critical feedstocks, “the changing energy profile has everything up for debate” in
the coatings industry’s drive to innovate.
The American Coatings Conference will be held in conjunction with the American
Coatings Conference April 7-10.
