tective coatings by making them
both more environmentally friendly
and less labor intensive. For example,
the Ecosonic Conformal Coating
powered by Nano-VpCI for use
as a circuit-board conformal coating
combines moisture-intrusion prevention
and corrosion resistance
with the company's Vapor-phase
Corrosion Inhibitor (VpCI) technology
(Figure 4). It contains an optical
identifier visible with ultraviolet
light, assuring rapid and effective
visual confirmation of proper coating
on surfaces. The coating is VOCfree,
fast-drying and a single-component
formulation, which is easier
to use than two-component coatings,
eliminating the need for special metering
and mixing equipment.
Cortec saw another opportunity
to help customers reduce labor costs
in the area of structural restoration,
says Cliff Cracauer, vice president of
sales with Cortec. " In the restoration
industry, there are great restrictions
regarding the mechanical removal of
old paint, corrosion, insulation and
other barrier materials, " he explains.
" To address this issue, we developed
a novel corrosion conversion coating
that eliminates the need to mechanically
remove corrosion in most
circumstances. This is subsequently
combined with a water-based coating
system that can increase the life
of a structure substantially. "
Cortec's VpCI CorrVerter Rust
Primer is a water-based primer for
application to rusty or poorly prepared
steel surfaces where further
corrosion protection is required and
good surface preparation is difficult
to achieve. The primer is formulated
to penetrate rust, eliminate
rust, penetrate to bare metal and
stop further rusting.
The chemical chelating agent
modifies the surface rust into a hydrophobic
passive layer. VpCI CorrVerter
combines the chelating agent
with a high-solids waterborne latex
with low water-vapor permeability.
The combination of the active chelating
agent with a film-forming latex,
thickeners and dispersant offers
a unique formulation for a primer
with protection against re-rusting.
" This product eliminates the need
to mechanically treat a metal surface
using sand blasting or dry ice
blasting, which meets the market
needs to reduce labor while substantially
increasing the life of a
structure, " says Cracauer.
" As we come up with these new
environmental and labor requirements,
as well as new applications
and capabilities that allow us to
build higher, dig deeper or run hotter,
we have to realize that it's not
the ability to engineer the pipe or
the skyscraper that allows these
projects, it's the coating that protects
the pipe or the skyscraper that
is truly the enabling technology, "
notes Dow Corning's Witucki. ■
