Heresite Develops Hydrophilic Topcoat in Response to Customer Requests

Heresite, a leader in the development of thin film corrosion resistant coatings, has launched HL-300, a robust hydrophilic coating for HVAC-R condensing equipment. The topcoat is designed to improve condensate management for reduced water carryover to allow for higher fan speeds on HVAC-R equipment.

“Our customers came to Heresite for a more durable solution to water carryover on HVAC-R equipment than was available at the time,” states Peter Hellman, General Manager for Heresite Protective Coatings. “HL-300 is the result of an R&D project to create a topcoat capable of providing a hydrophilic surface that exhibits corrosion resistance similar to P-413.”

Tests performed on HL-300 included immersion, QUV and salt spray  with positive results. HL-300 passed 3,000 hours of immersion, 2,500 hours QUV, and 2,500 of salt spray exposure with no visible degradation. HL-300 was also tested for chemical resistance against GAA, Sulfuric, and common coil cleaning chemicals with positive results.

About Heresite Protective Coatings

Established in 1935, Heresite Protective Coatings has spent more than 80 years developing and perfecting protective coatings that solve corrosion problems in a variety of applications including commercial heating, cooling, refrigeration or other industrial process coils, as well as components that are regularly exposed to corrosive conditions, including coastal and marine environments. The company’s ongoing focus on technology leadership, rigorous quality and process control, and customer satisfaction has led to the development of multiple industry-leading coatings based on phenolic, epoxy phenolic, urethane and silicone chemistries. Heresite coatings not only provide protection in corrosive high salinity marine conditions, but industrial applications such as wastewater treatment, swimming pools, food processing, mining, oil and gas, semi-conductor production, pulp and paper, textile factories and other environments where these systems are exposed to chemical fumes.
