Info About Bull Frog "Rust Blocker" (VpCI) Products
is an incredibly destructive force facing everyone. In the United States
alone, corrosion costs the consumer, over 350 billion dollars a year.
• Bull Frog
has developed a break-through additive technoIogy which offers highly
efficient and economical protection for the consumer. Many other corrosion
protection methods employed are less than effective, and worse, are inherently
damaging to the earth's environment.
• Through commitment,
extensive research and development, Bull Frog pioneered the application
and distribution of VpCI (Vapor Phase Corrosion Inhibitor) technology.
• Bull Frog
products are environmentally acceptable, water-based products that effectively
replace traditional polluting oil/solvent based coatings.
• Bull Frog
VpCIs are self-replenishing. While conventional anticorrosion coatings,
such as paints, remain fixed, Bull Frog VpCIs are highly mobile. VpCIs
are attracted to areas with potential for corrosion, just like a magnet.
Bull Frog products extend the life of the protected item by providing
protection in all three phases: liquid, interphace and vapor phase.
• The driving
force that causes metal to corrode is a natural consequence of their temporary
existence in metallic form. To create a metallic substance, it simply
takes some natural ore with energy added, in the form of heat or compression.
This addition of energy forces the natural ore to transform into metallic
substance. Therefore, metal is simply natural ore and stored up energy.
Natural Ore + Energy = Metallic
• In order
to start the corrosion process, four things are necessary: the cathode
the anode an electrical path between the two and an electrically conductive
• When these
four things are brought together a corrosion event is set in place. There
are also two major influencers on the corrosion process: Galvanic and
corrosion event can occur where a steel fence post shaft is partially
exposed to the soil and partially embedded in concrete. The fence post
alone serves as cathode, anode and the metallic connection between the
two. The portion of the shaft in concrete serves as the cathode and the
portion exposed to the soil becomes the anode.
• The principal
factors influencing atmospheric corrosion for a given metal are moisture,
temperature and the presence of contaminants in the environment. Corrosion
severity is further increased when salt, sulfur compounds and other atmospheric
contaminants are present.
• Vapor Phase
Corrosion Inhibitors (VpCI's) are corrosion inhibiting compounds some
or all of whose ingredients have sufficient energy (vapor pressure) to
release molecules from the compound into the air and ultimately to block
the corrosive effects of electrolytes. Bull Frog products contain proprietary
chemical systems which emit a non toxic vapor which is diffused throughout
the air. Electron scanning instrumentation shows that the VpCI laden atmosphere
causes VpCI molecules to condense in a microscopic layer on all surfaces
they can reach. Metal surfaces are passivated by the condensed molecules.
The inhibiting layer is maintained as long as the product protected with
a VpCI layer revolatilizes from the surfaces. Within two hours, the VpCIs
leave a clean, dry and corrosion-free product.
• VpCI's condition
the air with trace amounts of inhibitive material. Protective vapors disseminate
in the air through vaporization. The inhibiting process begins when the
vapors contact the metal surface and condense to form a thin protective
crystal layer one or two molecules thick. In the presence of even minute
quantities of moisture, or acids the crystals dissolve and form a protective
film between the moisture layer and the metal surface. The presence of
this film prevents corrosion of the metal surface.
