CORTEC’S 329 D ES IN EASY SPRAY FORMULA:
POWERFULL, LONG-TERM CORROSION
PROTECTION OF YOUR ASSETS!
VpCI®-329 D ES is a ready to use spray
providing strong rust prevention for metals
in indoor and outdoor sheltered conditions.
The product can be easily applied/sprayed
from a handheld trigger spray bottle. It
offers a convenient way to protect gears,
spindles, coils, or any other metal parts
that require a light coat of oil for further
processing and shipment. VpCI®-329 D ES
contains innovative Vapor phase Corrosion
Inhibitors (VpCI®) technology and its carrier
is a combination of
bio-based oil and mineral spirit. By spraying
VpCI® 329 D ES, the corrosion is attacked on
two fronts. Its oil-soluble corrosion inhibitors
first create a tenacious film that clings to
metal surfaces, providing excellent contact
corrosion protection.
VpCI’s release into the air and attach
electrochemically to the metal surface.
The coating provides universal corrosion
protection to ferrous and non-ferrous
metals and performs effectively even under
the adverse conditions of 100% relative
humidity as well as the presence of corrosive
species such as chlorides, hydrogen
sulfide, or other sulfur compounds. The
product does not contain any hazardous
chromates, nitrites, or phosphate inhibitors.
It is thermally stable, providing long-
lasting contact and vapor phase corrosion
protection for a wider variety of applications.
SUCCESSFUL CORROSION
PROTECTION OF SPEED
REDUCERS WITH VPCI® 329 D ES
Merger is a leading world manufacturer
of power transmission gears. Their teams
have been working to bring power
transmission solutions to manufacturing
companies for more than 70 years. The
sensitivity of their reduction gears requires
them to be protected against corrosion
during shipment, storage and in between
manufacturing processes. Because of this
Merger relied on Cortec’s expertise and
highly advanced corrosion protection
solutions. VpCI®-329 was used at a low
concentration to protect the internal areas
of speed reducers and gears. The product
was poured into the bottom of the gear

case lubricant reservoir at only 0.3% of total
volume. The oil-based solution provided
double action against corrosion. VpCI®-329
works in the contact phase for protection
of immersed metal surfaces, while vapor
phase action allows the inhibitors to
migrate effectively to non-immersed and
remote areas where they adsorb and form
a protective layer. For exterior protection,
external surfaces were sprayed with Cortec’s
CorShield® VpCI®-369, a temporary coating
that leaves a moisture-displacing protective
film, providing superior protection against
aggressive environments.
VpCI®-329 will protect against corrosion for
up to four years. Stephane Morel, a sales
manager at MERGER, commented that the
company now uses VpCI®-329 on all their
strategic speed reducers designed for lifting
in the manufacturing sector. The efficiency
of using VpCI®-329 at low concentration
has resulted in cost savings and increased
shipping safety. There is no more need to
fill the entire case with lubricating oils, and
the company has even been able to save
on freight that is no longer considered
hazardous.
