Corrosion 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 technology 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, interphase 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 Substance
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
electrolyte.
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
Atmospheric interaction.
Galvanic 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.
