Hydroplate 6500 - Epoxy Lining for Severe Wastewater Protection

Hydroplate 6500 is an ultra-high build, 100% solids epoxy lining engineered by Carboline for superior protection in aggressive, hydrogen sulfide-rich municipal and industrial wastewater environments. This glass-flake- and ceramic-reinforced formulation delivers exceptional chemical resistance, outstanding abrasion resistance, and remarkably low permeability — making it the premier choice for immersed steel and concrete in severe wastewater, water transmission, and corrosive industrial service. VIEW THE ENTIRE LINE OF CARBOLINE COATINGS HERE › Key Features: Ultra-High Build — Up to 250 Mils in a Single Coat: Batch mix formulation achieves 20–250 mils DFT per coat with standard airless spray equipment, eliminating multiple coats and dramatically reducing application time and project downtime. Passes ASTM G210 Severe Wastewater Analysis Test (SWAT): Glass flake and ceramic reinforced for outstanding chemical resistance to hydrogen sulfide, biogenic acids, and aggressive wastewater compounds in the most demanding H2S environments. Fast Return to Service: Cure to immersion service in water and wastewater environments in as little as 10 hours at 75°F — minimizing infrastructure downtime for operating wastewater facilities. NSF/ANSI/CAN 600 Certified: UL-classified for potable water exposure — certified for tanks greater than 200,000 gallons at 1–2 coats under 125 mils. Valid when manufactured at a certified location. Low-Temperature Cure: Surface application minimum of 30°F (–1°C) enables year-round application even in cold-climate wastewater infrastructure projects. Low Application Pressure: Achieves 250 mils per coat at spray pressures as low as 2,500 PSI — reducing applicator fatigue, equipment wear, and pump stress compared to competitive products requiring 5,500–6,000 PSI. Meets AWWA C210: Qualified for water transmission pipe, ductile iron pipe, and immersed infrastructure meeting AWWA C210 requirements. NSF/ANSI/CAN 600: UL-classified for potable water tank exposure (tanks >200,000 gallons, 1–2 coats <125 mils, cure to service 1 day). Valid when manufactured at a certified location. AWWA C210: Meets the requirements of AWWA C210 for liquid-applied internal linings for steel water transmission pipe and related infrastructure. ASTM G210 (SWAT): Passes Severe Wastewater Analysis Test for use in aggressive municipal and industrial wastewater environments. Common Industry Applications: Municipal Wastewater Treatment: Clarifiers, digesters, lift stations, collection systems, and manholes in hydrogen sulfide-rich, highly corrosive environments. Water Transmission & Pipe Lining: Ductile iron pipe, water transmission lines, and immersed steel and concrete structures requiring AWWA C210 compliance. Potable Water Infrastructure: Water treatment facilities and tanks greater than 200,000 gallons requiring NSF/ANSI/CAN 600 certification. Industrial & Severe Service Facilities: Immersed steel and concrete in chemical processing, industrial wastewater, and other aggressive corrosive environments demanding long-term durability.
