Insitu® Spray Applied Coating Technology

ES2 Technology

The ultimate in corrosion protection is Insitu® ES² Spray Applied Coating – a unique and proprietary water-based and water-reducible synthetic flexible polymer anti-corrosion coating specifically designed for the protection of HVAC/R coils, exposed components and cabinets.

ES2 pigments are made from a high-performance stainless alloy which are resistant to corrosive conditions.  ES² pigments form a multi-layer structure throughout the paint film.  This creates a barrier layer that reflects sunlight away from the paint film and the multi-layer structure of the ES2 pigments also slows the passage of water molecules into the film and acts as an effective moisture barrier.  This prevents the subsequent swelling and deterioration of the protective film.

As a result, the film integrity is maintained, and the pigment particles are well anchored to the substrate preventing ultraviolet rays and moisture from penetrating making it the application solution for even the most corrosive environments.  The resultant smooth, hard finish stops dirt from accumulating thus maintaining its appearance for many years.

This proprietary formulation is environmentally friendly, it is compliant for application in all 50 states, has low VOC, zero HAPS, no PFAS, chemicals, non-ozone depleting chemicals and is non-flammable adding to the attributes of this superior product.


The coating process will ensure a uniform dry film thickness of 0.6- 1.2 mils and meet 5B rating crosshatch adhesion per ASTM D3359- 93.

Corrosion durability will meet a minimum 15,000 hours salt spray resistance per ASTM B117.
