/Why isn’t the QPR® 50lb 6690 Hot-Applied Crack Sealant completely hardened?

After QPR® 50lb 6690 Hot-Applied Crack Sealant has been applied and allowed to cool, it is designed to remain flexible, allowing it to expand and contract with the outside air climate. It is normal for this type of material to flex to the touch. It will also temporarily retain car tire treads if parked on.
