ECRA-SHM – Self-Etching Dip Coating

Factory-Applied Coil Protection for Maximum Durability

ECRA-SHM is a water-based self-etching epoxy resin formulated for the coating of all ferrous and non-ferrous metals used in HVAC coil manufacture. Applied via dip coating, it delivers a uniform, high-gloss, super-hydrophobic finish that protects every surface — including internal tube walls — from corrosion, fouling and biofilm growth.

Key Benefits

• Permanent Super-Hydrophobic Barrier – Repels condensate and prevents dirt build-up for cleaner coils and faster heat transfer.
• Long-Term Corrosion Protection – Maintains coil integrity and thermal efficiency even under harsh marine or industrial exposure.
• Anti-Microbial Defence – Embedded Ag+ silver-ion technology inhibits mould and bacterial growth.
• Ultra-Thin Profile (6–8 microns) – Zero impact on heat exchange or airflow performance.

ECRA-SHM is the OEM’s choice for factory coating of coils — ensuring lifetime protection, stable performance, and reduced maintenance costs from day one.
