QUIKSTEEL- FSL epoxy putty is the only full strength steel epoxy product that fully cures in one hour. Quiksteel- FSL epoxy putty sets up in 5 minutes, dries steel hard in 15 minutes, and is fully cured in one hour. 2. QUIKSTEEL- FSL epoxy putty is the only fast drying epoxy putty that can be drilled, tapped, machined, sanded and painted in one hour. 3. QUIKSTEEL- FSL epoxy putty provides longer working time than other fast drying putty products to permit molding and to flow completely into cracks and holes for a complete repair. 4. QUIKSTEEL- FSL epoxy putty is the only epoxy putty that has a 500F (260C) continuous operating temperature range. 5. 1:1 mixing 6. Fast setting (5 minutes); steel filled (machin-able) 7. Unique semi-solid putty consistency ideal for overlaying8. Vibration resistant9. Temperature resistant up to 500F 10. Unmatched mechanical properties & surfaces adhesive vis--vis other fast curing epoxies 11. Superior chemical resistance FAST DRYING: Quiksteel- FSL epoxy putty sets up in 5 minutes, is hard like steel in 15 minutes, and is completely cured and ready to drill, sand, tap, prime, and paint in one hour. STRONG: SHEAR STRENGTH- QUIKSTEEL- FSL Epoxy putty has shear strength of 680 pounds per square inch for comparison; pine lumber has shear strength of 400 pounds per square inch. Quiksteel- FSL epoxy putty is more ''than one and one-half times as strong as pine. TENSILE STRENGTH - QUIKSTEEL- FSL Epoxy putty has a tensile strength of 5,700 pounds per square inch. This would mean that a piece at Quiksteel one-inch in diameter could lift the weight of two compact automobiles. HARD: QUIKSTEEL- FSL Epoxy putty is one of the hardest materials next to steel. Technically, it is rated at D-84. "D" is the highest hardness rating in the shore rating system. Quiksteel- FSL epoxy putty can be compared to ABS plastic (material used to manufacture automobiles) or the fiber epoxy wings on the B2 bomber. When cured, QUIKSTEEL- FSL epoxy putty can be machined, milled, or turned on a lathe. It can also be drilled, tapped, sanded, sawed, routed, primed and painted. Anything you can do to metal or wood - you can do to QUIKSTEEL- FSL epoxy putty. SEALS LEAKS UNDER WATER OR IN FLUIDS: QUIKSTEEL- FSL epoxy putty cures under water and in all atmospheric conditions. Leaks can be sealed inside a container, tank, etc with liquids still in the item to be sealed. SEALS LEAKS WHILE LEAK IS OCCURRING: if a gasoline or diesel-tank, oil pan, or any container has a rupture, Quiksteel will seal the leak while the drainage is occurring. No need to empty container prior to repair.IMPERVIOUS TO CHEMICALS: QUIKSTEEL- FSL epoxy putty is impervious to most chemicals including battery acids.
