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.
