Product Description
Polycoat 750D is Polyurea coating a fast set, rapid curing, 100% polyurea, flexible, two-component Spray coating material. 750Dis used by itself or in combination with other materials to produce coatings, liners, wearing courses, and resilient surfaces on metal substrates. Its extremely fast gel time makes it suitable for applications down to -50oC and up to+200oC without special conditioning of the component resins and isocyanates. 750D produces an extremely tough film at all thicknesses. Single or multiple pass applications produce films from 0.5 mm to 25 mm without appreciable sag or runs. 750D may be applied in all positions and to any suitably prepared substrate. 750D is inert, it will not hydrolyze, leach, or contaminate other materials, and is bondable and paintable.

Uses
Polycoat 750D is Polyurea coating a superior coating material designed specifically for industrial applications receiving constant or intermittent attack from contained materials, most corrosive substances, and abrasive action. 750D is flexible, accommodating movement of the substrate, yet strong enough to remain intact under all conditions except major structural dislocations. With or without reinforcements 750D may be used in transitional areas with confidence. 750D may be used in interior or exterior applications. 750D is recommended for repair of other films, on damaged metal surfaces, or in new construction and in cold weather conditions.
