Industrial environments can expose electronics to hazardous materials including highly
corrosive gases, moisture, and debris. These vulnerabilities create a considerable risk of failure for
critical networking components. Corrosion is the greatest enemy and threat against electronic components. It
causes deterioration of materials due to interactions with the environment that leads to unforeseeable and
irreparable damage. In today’s market, most industrial networking equipment is not designed with this hazard
in mind. Antaira Technologies is proud to announce a new and advanced process of conformally coating
products. This process supports many of the sought-after certifications required in toxic environments.
Corrosion of materials is a chemical reaction caused primarily by an attack of gaseous
contaminants and is accelerated by heat and moisture. Environments like this are found in
industries such as water wastewater plants, mines, and chemical and power plants; but can
be found in many common outdoor applications. When field equipment has been operating in
air, moisture, and oxygen trigger corrosion on metal surfaces of electronic components. In
industrial environments, gases such as sulfur dioxide emitted from burning fossil fuels and
chloride found in water treatment plants will accelerate the corrosive process.
To determine the level of corrosiveness, the International Organization for Standardization
(ISO), the American National Standards Institute (ANSI), and the International Society of
Automation (ISA) have established a classification system. Antaira’s process for conformal
coating meets or exceeds some of the highest classifications for corrosive environments.
ISA Standard 71.04
Corrosion is not a factor in determining equipment reliability.
Effects of corrosion are measurable and may be a factor in determining equipment
High probability that corrosive attacks will occur. This harsh level should prompt further
evaluation and result in environmental controls or specially designed and packaged equipment.
ONLY specially designed and packaged equipment would be expected to survive.
Corrosion severity level of the environment is classified by four different types of airborne
contaminants: liquids, solids, gases, and biological influences.
C1 Very Low
Arid / Urban Inland
Coastal / Industrial
C5 Very High
Ocean / Off-Shore
The corrosivity of an atmosphere is classified based on measurements of pollution categories
(i.e. sulfur dioxide and airborne chlorides) and time of wetness.
Using the charts above, manufacturers and users can determine what kind of environments are
categorized as corrosive. In marine environments, for example, airborne salt crystals can
aggravate corrosion on the surface of electronics found near sea water.
