Generic Type Aromatic Polyurethane Hybrid
Common Usage A two-component, fast setting, monolithic coating designed to provide a durable polyurethane lining in a single-coat, multi-pass spray application applied with plural component equipment. This high performance coating has excellent chemical, thermal shock and abrasion resistance. It is ideal for application to steel or concrete in water and wastewater treatment, secondary containment and for tank linings and bottoms. Recommended for immersion service. Note: All orders are subject to approval based upon project scope, applicator qualification and appropriate equipment configuration.
Colors WH06 Off-White. Other colors may be available with minimum size orders, contact your Tnemec representative. Note: Colors will change when exposed to sunlight.
