Potable Water Linings | NSF 61 & 600 Certified
December 2025
Certified Potable Water Solutions
Duromar now offers two industry-leading products that carry Underwriters Laboratories (UL) certification to NSF/ANSI/CAN 61 and NSF/ANSI/CAN 600, specifically engineered for potable water service and safe contact with drinking water systems:
Duromar HPL-1110-PW: Immersion-Grade Potable Water Lining
A high-performance, 100% solids, zero-VOC epoxy lining formulated for immersion service in potable water infrastructure, including tanks, vessels, and process piping. HPL-1110-PW retains the excellent flexibility and corrosion resistance Duromar is known for, while now meeting the stringent health effects criteria of both NSF/ANSI/CAN 61 and NSF/ANSI/CAN600 for safe use in drinking water contact environments.
Duromar GMC-PW: Patching & Local Rehabilitation Epoxy
A versatile patching-grade epoxy compound designed for minor repairs and localized rehabilitation of potable water systems. GMC-PW provides long-term chemical and environmental resistance in small-project applications such as pipe splices, valve bodies, and pump casings while also meeting NSF/ANSI/CAN 61 and NSF/ANSI/CAN 600 certification requirements.
Why This Matters for Water & Wastewater Applications
- Certified for Potable Water Contact: Both products are certified for compliance with drinking water health effects standards recognized throughout North America and in global regions that follow NSF/ANSI/CAN 61 and 600.
- Safe for Critical Infrastructure: These technologies deliver non-toxic, low-emission performance while ensuring that drinking water systems remain protected from corrosion, leaks, and contaminants over their service life.
- Fast Return to Service: Engineered for ambient cure with no force curing required, they help minimize downtime for essential water treatment and distribution assets.
