Hi-Chem™ 21-70 Data Sheet

Part A – Hi-Chem™ 21-70 Iso – Part # 60060 Part B – Hi-Chem™ 21-70 Resin – Part # 60070

DESCRIPTION: Hi-Chem™ is a two-component, 100% solids (no VOCs, no solvents), exothermic, rapid curing, elastomeric polyurethane lining system specifically designed for excellent chemical resistance.

TYPICAL USES:

• Durable protective lining with excellent chemical resistance for applications such as:

-primary and secondary containment -chemical processing equipment, tank lining and wet wells -water and wastewater -immersion service

• Spray-on application creates a monolithic, seamless lining which conforms to any shape and size.

• Stable from -5˚ F to 170˚ F (-20.6° to 76.7˚ C)

FEATURES & BENEFITS:

• Excellent corrosion resistance

• Excellent chemical resistance

• Dense chemical structure imparts high impermeability
