Manitowoc, Wis. (April 29, 2019) – Heresite, a leader in the development of thin film corrosion resistant coatings, has been listed in The American Institute of Architects (AIA) MasterSpec Construction Specification Resource. MasterSpec® is the industry-leading building and construction specification resource. Specifications are written by professional specifiers, architects, and engineers,
In 1995, The Society for Protective Coatings (SSPC) published a paper that concluded, “It is obvious that ASTM-B117 Salt Spray (Fog) Testing and similar methods offered a rapid but unreliable means for predicting coating behavior.” For the 20+ years since that paper was published, the ASTM B-117 salt spray procedure
Heresite, a leader in the development of thin film corrosion resistant coatings, recently completed a UV-C exposure test on its P-413 coating, both with and without a topcoat. The test was conducted in conjunction with Sanuvox Technologies laboratory. UV-C lights are used in many HVAC systems to sterilize HVAC coils
Coating extremely large HVAC-R units or coils can be difficult. Their size (both dimensions and weight) makes the units/coils difficult to move and many coating applicators find it difficult to thoroughly apply coatings to protect them from corrosive elements. A large HVAC-R unit/coil is clearly a big investment, which makes
Heresite, a leader in the development of thin film corrosion resistant coatings, has released a new whitepaper, Choosing an HVAC-R Coating for Marine Environments. The whitepaper was developed to answer common questions around evaluating the options for HVAC-R coil coatings in offshore and coastal marine as well as other corrosive
To further expand on Heresite’s expansive chemical resistance guide, P-413 coated steel, copper, and aluminum panels were placed in a municipal wastewater treatment facility to simulate sewage fumes. Panels were placed at the point where raw sewage is pumped into the facility and screened; this results in significant hydrogen sulfide
ASTM B-117 was the first nationally recognized salt spray standard. Published in 1939, this salt spray test is widespread and often recognized as the “gold standard” in corrosion testing. However, ISO 20340 offers a more realistic and updated method of testing, representing a significant improvement over ASTM B-117. When the
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
Heresite, a leader in the development of thin film corrosion resistant coatings, has now become the only company with a NSF/ANSI 51: Food Equipment Materials rated phenolic-epoxy for HVAC-R coils. The NSF rating establishes that Heresite’s P-413 coating has been shown to meet the requirements for materials and finishes used
HVAC-R coating chemical resistance is often tested using fume exposure. While this method of testing can provide information on the anticipated level of protection for HVAC-R equipment, in certain applications, spot/direct exposure tests may provide better information about your equipment’s longevity in real-world conditions. It is important to conduct spot/direct
