Tensile Strength
The KwikWeld has a tensile strength of 3127 PSI, which means that one square inch of KwikWeld has enough strength to hold 3127 lbs.
On the other hand, J-B Weld Original Cold-Weld has a tensile strength of 5020 PSI, which means that one square inch of Cold-Weld is strong enough to hold 5020 lbs.
The Original Cold-Weld is much stronger than the KwikWeld.
Set & Cure Time
