Bio-Dur 561 Rises To The
Challenge
A large, oil-fueled power station
located on the Gulf of Mexico in
California receives fuel oil from
tankers which unload at a deepwa-
ter terminal. The discharge termi-
nal is built at the end of a 1.2-km.
long concrete pier built on 30 and
36-in. diameter steel pilings.
The integrity of the pier is critical
to the operation of the power sta-
tion. In order to maintain the pro-
tective coating system, it was nec-
essary to apply a barrier type sys-
tem under conditions of vigorous
wave action or complete submer-
sion.
Because of the size of the project,
old-fashioned "splash-zone" type
putties were too difficult and slow
to apply. Bio-Dur 561 is formulat-
ed to be of a thick and pasty, but
easily spreadable viscosity.
Using putty knives, divers were
able to obtain a consistent 30-50
mm. thickness under all conditions
— even at the waterline when
applying in wave action.
Bio-Dur 561 was applied over the
steel piling surface which had been
freshly blasted using 4,000 psi
water with entrained river sand
abrasive. The surface obtained

was a mixture of white metal with
islands of roughened, tightly
adhering, existing coating which is
highly suited for this application.
The divers and other workers
employed in this project had little
previous experience in this type of
work, but were reportedly able to
properly mix and apply the Bio-
Dur 561 and obtain an excellent
result. Under the conditions of
application in approximately 65-
85 degree F water, the Bio-Dur 561
cured to a firm film after six to
three hours, respectively, and was
hard overnight. Wave action
reportedly had no effect, even
immediately after application,
before any curing had taken place.
The "wind and water" area of this
structure is now protected with 30
-50 mm. of tough, impermeable
and tenaciously attached epoxy
coatings. According to reports, the
work was performed with excellent
productivity and without the need
for complicated mixing or applica-
tion equipment.

New Coating For Chemical
Cargo Tanks
A new coating for chemical cargo
tanks was developed by Advanced
Polymer Sciences, Inc. (APS),
which the company claims will "re-
volutionize
the chemical
and products
carrier indus-
try's think-
ing."
The tank
coating, dub-
bed Marine-
Line, "elimi-
nates the re-
quirement for
stainless steel
tanks and the
currently-used
ranges of spe-
cialty epoxy or inorganic zinc sili-
cate coatings," said Don Keehan,
technical director. The bottom line
is potential cost savings and
improved earnings.
MarineLine is a high perfor-
mance tank lining, formulated
with the patented Siloxirane poly-
mer resin technology. This cross-
linked aerospace polymer struc-
ture is engineered to provide
improved protection against corro-
sion and contamination by total
prevention of cargo permeation.
The coating can reportedly han-
dle the marine environment and
virtually all sea-approved bulk car-
goes. The total range is available
in the company's Marine Tank
Lining Guide, which lists more
than 4,000 chemicals and prod-
ucts.
