Heresite Coating
Heresite Coating
Heresite provides high-performance protective coatings designed to reduce equipment damage, increased maintenance costs, downtime, and reduced energy efficiency caused by corrosion in HVAC-R systems.
Since first applying an anti-corrosion coating to HVAC coils in 1964, we have continued to develop coating technologies that withstand a variety of corrosive substances, including salt, acid rain, hydrogen sulfide, ammonia, and chlorine. Heresite coatings feature low heat loss, excellent flexibility and durability, and can withstand temperatures ranging from sub-zero to approximately 204°C, as well as thermal shock.
Key application areas include marine environments, wastewater treatment, swimming pools, food processing, mining, oil and gas, semiconductors, pulp and paper, textiles, agriculture, transportation, and highly contaminated industrial environments. Applying the appropriate Heresite coating can extend the service life of HVAC-R equipment, reduce maintenance costs and energy loss, and improve operational efficiency.
Business Sectors
P-413 Phenolic Epoxy
Heresite P-413 is a high-performance, thin-film thermosetting phenolic epoxy coating designed for use on HVAC-R coils, radiators, and air and smoke handling equipment. It meets the ISO 12944-9 standard and offers excellent resistance to marine and saline environments, as well as various corrosive chemicals, vapors, and condensate. With its thin film, it effectively extends the service life of equipment while keeping heat transfer losses below 1%.

P-403L Phenolic
Heresite P-403L is a high-strength phenolic resin coating used for the storage and transportation of chemicals in railcars, ISO tanks, and storage tanks. It is suitable for acidic environments with a pH below 9 and offers excellent resistance to solvents, acids, and salts. It can also be applied in environments containing sulfuric acid at concentrations of 70–98% at temperatures up to 49°C.

UC-5500
Heresite UC-5500 is a two-component protective coating developed for use as a topcoat over existing Heresite coatings, featuring a high-gloss finish. It offers excellent UV resistance and weather resistance, as well as superior flexibility and abrasion resistance. It is primarily applied by spraying to the exterior surfaces of process equipment, transport containers, tanks, and structural steel.
