RectorSeal, Houston, has been named the master distributor for GulfCoat by Modine Louisville Inc., Louisville, Ky., and its subsidiaries (Modine Coatings), which provide global coil coating services. The partnership calls for RectorSeal to market GulfCoat, a contractor-applied HVAC/R system coil, component and cabinet corrosion-resistant coating, throughout North America and Australia.
GulfCoat is available in 12-ounce (340-gram) aerosol cans. The water-based synthetic polymer blue or clear coating extends HVAC/R coil lifecycles in corrosive environments with negligible thermal heat transfer loss.
GulfCoat offers contractors a field or shop-applied coil coating protectant equivalent to Insitu, a factory-applied spray coating process from Modine Coatings that’s preferred by specifying engineers and commercial OEM manufacturers for HVAC/R equipment installed in corrosive environments.
GulfCoat was designed to protect new and existing HVAC/R equipment from corrosive coastal air and passed ASTM B117 test standards for salt spray. It also passed multiple marine and industrial ASTM test standards for resisting ultraviolet (UV) rays, acid rain, high concentrations of urban vehicle emission air pollutants and other outdoor contaminants that corrode unprotected coils and components.
Unlike some protective coatings, GulfCoat’s 0.4 to 1.4-mil coating boasts thermal degradation of less than one-percent and actually helps maintain optimal thermal heat transfer over the lifecycle of the coils because its gloss finish deters debris, dirt, mold and moisture accumulation. Likewise, GulfCoat’s finish also helps maintain system static pressure and airflow efficiency.
One can of GulfCoat coats a residential unitary split system, mini-split or light commercial HVAC/R unit of up to 2.5-tons or a maximum 8-square-feet of coil space. Multiple can applications can also be contractor-sprayed uniformly throughout coils two-rows-deep and less on packaged rooftops, large condensers, modular air handlers, air-cooled chillers and other equipment. Components, as well as exposed line sets and other copper piping are also ideal coating candidates.
An application instructional video is available online. Application steps:
- 1) disassemble unit cabinet
- 2) masking components that don’t get coated
- 3) removing manufacturing process chemicals/oils residue with RectorSeal Clean-N-Safe aerosol coil cleaner, then rinsing
- 4) applying GulfCoat
- 5) reassemble unit cabinet.
The technical support department at RectorSeal is also available for instruction.
Other GulfCoat features:
- Passed multiple ASTM test standards for salt spray; water immersion; pencil hardness; cross hatch adhesion; humidity; UV resistance and flexibility; mold resistance; sand and dust resistance
- Available at traditional HVAC/R wholesalers in single cans or six-can cases
- Once applied, semi-annual or annual cleanings are recommended
- Doesn’t affect OEM warranties
- The clear coat is invisible, while the blue coat helps installers inspect coil coverage uniformity
