What challenges does HiGANiC address?
It is a protective coating designed to reduce corrosion-related deterioration of heat exchangers and components made from non-ferrous metals such as aluminum and copper.
Corrosion resistance and heat-transfer performance in heat exchangers
Air handling units, coils, ducts and unit coolers can be exposed to condensation, salt, moisture, UV radiation and corrosive gases. Assemblies joining aluminum, copper and zinc may also be susceptible to galvanic corrosion.
Reduced Heat Exchange Performance
Corrosion and whitening of fins can impair heating and cooling efficiency and precise temperature control.
Equipment Deterioration and Leakage
Corrosion can reduce housing strength and increase the risk of leakage.
Higher Energy and Maintenance Costs
Progressive corrosion can increase energy consumption and maintenance costs.
Airborne Corrosion Products
Corrosion can release aluminum-oxide or zinc-oxide particulates into the air.
Clear and Silver coating specifications
Available in two types: a clear formulation with non-metallic constituents and a bright metallic-silver formulation containing zinc and aluminum.
HiGANiC-Clear
Clear Coating
A clear formulation with non-metallic constituents. Its electrical insulation properties, including a reported 25 A current-isolation test, support evaluation for dissimilar-metal interfaces and precision environments sensitive to conductive contaminants, such as data centers and cleanrooms.
