Curran 500 is an advanced two-part, 100% solids epoxy coating formulated for immersed service in harsh industrial environments. This high-build coating can be applied in a single, thick layer to repair and protect steel surfaces exposed to water or hydrocarbons.
Once cured, Curran 500 creates a durable barrier with exceptional corrosion resistance and foul-release properties, ideal for mitigating both rust and fouling deposits on metal equipment. With zero volatile organic compounds (VOC) and a high-gloss finish, Curran 500 provides a smooth surface that reduces fluid drag while protecting critical assets.
Water-side equipment faces relentless attack from corrosion and fouling in cooling water systems. Traditional coatings often fail prematurely due to poor adhesion, water permeability, or inability to withstand thermal cycling.
Typical uncoated equipment life
Curran 500’s 100% solids epoxy formulation bonds tenaciously to steel substrates with ~3,800 psi adhesion strength. The coating’s ultra-smooth finish and foul-release properties significantly reduce deposit accumulation.

Enjoy reduced maintenance and improved reliability over the next decade.
01
Curran 500 requires SSPC-SP 6 commercial blast minimum, with 3 mil surface profile for optimal adhesion. Higher levels of surface preparation will extend coating life.
02
Equipment must be taken offline, cleaned, and dried before application. The coating can return to water immersion service 24 hours after application when tack-free
03
Applications have routinely demonstrated 10+ years of service life in cooling water systems, with some installations exceeding that timeframe.
04
With ~3,800 psi adhesion strength and 7-9 perms water vapor transmission, Curran 500™ provides superior barrier protection compared to traditional epoxy coatings.
05
Yes, damaged areas can be repaired by abrading the affected area and applying additional coats to the required DFT following proper surface preparation.
