AboCast/AboCure 8007-2 is a 2-part polysulfide-epoxy solventless system. It is weather- and water-proof, flexible, and acid, alkali, and fuel resistant. Uses: Filling joints and cracks in exposed structures like bridges, docks, parking garages, and flat roofs; Repairing cracks and joints between concrete and steel; Installing and sealing bulkheads, windows, and other framed openings in ships and buildings; Maintenance of tanks, pipes, and structures; Repairs in sewage, drainage basins, and pipes; Metal and concrete structures. The 8007-2 system is a compromise between a rigid patching material and a flexible sealant with high elongation, for cases where the first would crack because of its rigidity and the second would offer poor tensile strength, adhesion, and wear resistance because of softness. It most successful use is in repairs of floors, walls, and ceilings in exposed decks typical of multilevel parking garages, helicopter landing platforms, flat roofs, gasoline service stations, loading docks, wharfs, piers, and multilevel warehouses. The 8007-2 system is also ideal where concrete is to be cast onto old concrete or steel and form a permanent bond that offers sufficient strength as well as a modest degree of flexibility that is sufficient to resist thermal expansion differences and other slight relative motions. The 8007-2 system also offers the ability to harden on wet surfaces and under water. In many cases, it can be used as a versatile binder to mix with aggregates or sand that can be used to patch and bond to surfaces where concrete aggregates could not bond. |
