The Product

Choosing the Right Solution for the Job.

Choosing the most appropriate coil coating for the application could save the project thousands of dollars and eliminate repeat treatments. Choosing the wrong coil coating could reduce heat transfer properties and lead to higher energy bills, premature failure, and unnecessary costs.

Description of the Solution

  • Durability

    • Chemically bonded - does not allow corrosion to grow under the coating
    • Flexible and scratch resistant - it will not crack or peel off
    • Resistant to chemicals found in HVAC/R environments
  • Improves Indoor Air Quality

    • Hydrophobic surface – inhibits mold and bacteria growth
    • Seals HVAC/R components from the environment
  • Energy Savings

    • Thin DFT (dry film thickness) – no bridging & will not insulate unit
    • Preserves original equipment efficiency throughout its life time
    • Improves heat transfer by filling microcavities
  • Reduce Equipment Replacement Costs

    • Extends the useful life of HVAC/R equipment
    • No harsh chemicals required for maintenance
    • 5 year standard warranty with an option for a 10 year extended warranty.

How it works

    • All epoxy, phenolic, and polymer based coatings adhere to the surface via mechanical bonding and attach to the micro-imperfections of the surface. This bonding results in a lower adhesion strength. Combining this flaw with the added pressure created by corrosion (~ 2,200 psi), the coating can start to blister or peel off the surface of the substrate.

      Chemical bonding provides unmatched surface adhesion. SURFSIL chemically (covalently) bonds with the substrate and cures with an adhesion strength of over 4,000 psi to become, in a sense, a NEW material.


Which side would you like your coil to look like?

  • Problem / Solution

    Test performed for 5,000 hours using ASTM G85 A3 (a more aggressive, modified ASTM B117 using acidified sea water). The image above compares the performance of a bare coil, half of which has been treated with SURFSIL and half left untreated.

  • Problem / Solution

    As the image above shows, even the micro-channel coils tested, using the ASTM G85 A3, shows how our intelligent coating design is able to penetrate into all the cavities of the coil, essentially sealing it from its environment and protecting it from corroding.
