nology and the use of a novel anti-
foulant.
The company's popular, non-pol-
ishing coating, Classic, is now avail-
able in a tin-free version.
Hempel's new ablative antifoul-
ings for the commercial shipping
market function in a similar manner
to copolymer types in that the ap-
plied film gradually diminishes
through physical erosion during
time in service. As with copolymer
types, this provides for exposure of
a fresh active layer of antifoulant.
The difference lies in their mode
of action/control which (not being
on the molecular level) may be con-
densed as a mainly physical, as op-
posed to chemical, process. In this
sense, the ablatives can be consid-
ered as polishers rather than self-
polishers.
INORGANIC COATINGS

Inorganic Coatings, Inc., Mal-
vern, Pa., manufactures and
markets IC 531, a high-ratio, water-
based, silicate/zinc coating.
Developed by NASA, IC 531 is
based on breakthrough silicate tech-
nology which the company claims
offers virtually permanent protec-
tion for steel. It is a no-cure inor-
ganic zinc which dries in 30 minutes
and can be topcoated in two hours
or less. Because it is water-based, it
has zero volatile organic com-
pounds, thins with water and does
not generate hazardous waste.
IC 531 is NAVSEA approved un-
der Chapter 631, paragraph 631-
7.97 of the Naval Ships Technical
Manual and is currently being used
in marine and offshore industries on
a variety of equipment and applica-
tions.
Inorganic Coatings has taken the
corrosion protection of IC 531 sili-
cate/zinc and coupled it with high
performance, water-based and high
solids coatings to offer premium
systems for nearly every application
and environment. Inorganic Coat-
ings representatives offer assistance
with proper coating selection and
specifications.
Inorganic Coatings has become a
leader in informing the marketplace
on the performance of water-based
coatings and low VOC products.
The company sponsors seminars on
water-based coatings several times a
year across the U.S., and is current-
ly publishing a new catalog which
not only addresses systems and
products, but includes historical
performance information and tech-
nical articles on corrosion, the eco-
nomics of coating systems and coat-
ing selection.

Tanker operators are now able to
carry a much broader spectrum of
"aggressive cargoes" with the use of
International Paint Marine Coat-
ings' Interchem TC 900, a tank coat-
ing series offering maximum flexi-
bility of cargo carriage.
The Interchem TC 900 system
utilizes innovative modified epoxy

technology allowing a greater degree
of chemical curing at ambient tem-
peratures and, thus, a greater cargo
resistance range compared to con-
ventional epoxy and epoxy-phenolic
systems. This is made possible by
the reaction of a high molecular
weight epoxy resin by way of its
active hydrogen groups maximizing
cross-link density within the film.
The system offers the widest spec-
trum of chemical resistance current-
ly available from organic tank coat-
ings. It is the result of three years of
concentrated research and develop-
ment into marine tank coatings by
UK-headquartered International
Paint Marine Coatings.
Interchem TC 900 series offers
tanker operators the opportunity to
carry such diverse cargoes as unres-
tricted vegetable oils, ketones, caus-
tic soda and methanol, without the
need for the post heat curing proce-
dures normally associated with tank
coatings of similar in-service per-
formance capabilities.
A key factor in this new tank
coating's flexibility is its resistance
to softening, even in low molecular
weight solvent cargoes. This is due
to the coating's optimized chemical
and physical properties which result
in a tough, resilient film which has
