our product

Infiniguard® outperforms traditional coatings with its ultra-durable, siloxane-based formula that bonds at the molecular level, delivering unmatched corrosion resistance, efficiency gains, and long-term protection. Proven in the harshest conditions, it’s the industry-leading solution for extending HVAC life and performance.


features

Infiniguard® coats every critical component — including coils, cabinets, tubing, and electrical panels — forming a seamless barrier against corrosion, moisture, and contaminants. No surface is left exposed.

Full system protection

boosts hvac efficiency

By reducing friction and improving laminar airflow across coils, Infiniguard® increases system efficiency by 8–13%. Units run smoother, use less energy, and experience less wear over time.

extreme durability

With a dry film thickness of just 0.5 mils, this thin yet powerful coating resists salt, UV rays, abrasion, and chemical exposure. It’s built to last in even the harshest coastal and high-humidity environments.

stops odor at the source

Infiniguard® uses a siloxane-based, inorganic coating that chemically bonds to metal at the molecular level. Unlike traditional organic coatings, it won’t peel, crack, or degrade — providing long-lasting, non-porous protection that stands up to salt, moisture, and extreme environments.

fda certified and field ready

Once cured, Infiniguard® is FDA-certified for food preparation surfaces, making it safe for use in sensitive areas. It can be applied to both new and existing units — even directly in the field.

Trusted Across The Carolina Coast

  • INFINIGUARD®-coated lab samples show virtually no coating degradation after exposure to 3 times the industry standard for cyclical corrosion.

    -Assured Testing Services

  • A typical duration for SAE J2334 is 40 cycles per most John Deere and Caterpillar (CAT) specifications. Following exposure to 120 cycles (120 days), INFINIGUARD® had 1 panel with a maximum of 3 percent corrosion. In comparison, the competitor’s panels had a minimum of 8% corrosion.

    -Assured Testing Services

  • After 12,000 hours of salt spray exposure, INFINIGUARD® exhibited far less oxidation and coating degradation when compared to the competitors.

    -Assured Testing Services

  • INFINIGUARD® coating subjected to the exposure of 12,000hrs at a thickness of 12 micron shows only minor visible defects. The majority of automobile frames and components are coated with e-coat around the 20-40 microns thick and rarely last longer than ~5000hrs in salt spray.
