Standard Resins & Colors
Corvex®
This isophthalic polyester resin system outperforms a number of competitive fiberglass and metal products. Corvex meets the requirements for corrosion resistance found in industrial, chemical processing, and water/wastewater applications.
Flame Spread: ASTM E84 rating of 25 or less.
Certifications: meets the USCG requirements for general fire rating*.
Standard colors: yellow, light gray, dark gray, or green.
Vi-Corr®
A superior vinyl ester resin developed for reliable performance in the toughest environments. It offers outstanding resistance to a wide range of highly corrosive situations, from caustic to acidic.
Flame spread: ASTM E84 rating of 25 or less.
Certifications: DNV GL Type Approval No. TAF000003C; ABS Type Approval No. 01-HS34733-X; meets the USCG requirements for general fire rating*.
Standard colors: orange or dark gray.
FGI-AM®
This food-grade isophthalic polyester resin system offers antimicrobial properties to inhibit the growth of bacteria on the surface of the composite to protect the product itself. FGI-AM provides the necessary corrosion resistance to meet the requirements of the food and beverage industry. This product is intended only for non-public health uses.
Flame Spread: ASTM E84 rating of 25 or less.
Certifications: USDA Approvable.
Standard colors: light gray or green.
XFR
This extra fire-retardant vinyl ester resin is recommended for use where fire potential is high.
Flame Spread: ASTM E84 rating of 10 or less.
Certifications: meets the USCG requirements for general fire rating*.
Standard color: dark gray.
ELS
This extremely low smoke resin is an acrylic-modified polyester system that is ideal for tunnel, offshore, mass transit and other confined space applications. ELS exhibits low ignitability, low smoke generation and extremely low smoke toxicity.
Flame Spread: ASTM E84: flame spread index of 25 or less, a smoke developed index of 100 or less and Fuel Contribution of 0.
Certifications: DNV GL Type Approval No. TAF000003C; meets the USCG requirements for general fire rating*.
Standard color: dark gray.
Super Vi-Corr®
This family of resin systems consists of more than 30 custom formulas engineered to provide corrosion control solutions in applications that are too severe for conventional FRP and other building materials. Each Super Vi-Corr resin was engineered for the best possible performance in specific chemical and/or elevated temperature environments.
These systems exist for aggressive chemical environments with exposure to solvents, acidic oxidizers, chlorine dioxide, sodium hypochlorite and liquid desiccants. Certain formulas are also suited for elevated temperature applications up to 400° F. Super Vi-Corr gratings are typically used for packing hold-downs and support in environmental and process scrubber applications.
Flame Spread: non fire retardant, unless specified.
Standard color: natural – tan to beige.
