Sealing polyurethane material that binds when exposed to moisture in the air. It provides a waterproof seal with good mechanical properties, is resistant to liquid slurry, chemicals and remains flexible over a wide temperature range.

Features

• one-component
• flexible
• resistance to municipal sewage, liquid slurry
• chemical resistance
• good mechanical properties
• high modulus of elasticity
• deformability 15%

Application

The product is used for sealing tanks in steel folded sections, such as enameled steel or stainless steel tanks, and for sealing systems in sewers. For indoor and outdoor use.
