The Armor JFX-35 Joint Filler is a technologically advanced, self leveling, 100% solids, two component, 1:1 ratio, Polyurea Elastomer joint filler. It is designed for concrete with low to medium thermal cycling. The Armor JFX-35 cures rapidly and consistently in applications ranging from -20ºF to 130ºF. It is tack free in 5 to 15 minutes and applications can be reopened to vehicle or foot traffic in 1 hour.
The Armor JFX-35 is highly flexible, allowing small slab movement, but strong enough to protect the vertical edges of concrete from spalling under extreme loading. It can be used on interior and exterior applications (exterior applications when little joint or crack movement from thermal cycling will occur.) Exposure to ultraviolet light may cause discoloration, however the physical properties are unaffected.
