Comments about JB Weld Marine Weld Epoxy:

I used the product to re-attach a pulley wheel that came off the main drive wheel of my car engine. The pully wheel holds the belt that runs my AC and water pump. It held fast for nearly 2 years. Saved me nearly $1800

        A:

        Hi Welch, glad to assist you! J-B MarineWeld is a specially formulated two-part epoxy cold weld system that provides for strong, lasting repairs for bonding different or similar surfaces, such as aluminum, metal, composites, fiberglass and others. MarineWeld sets in 4-6 hours at room temperature and is fully cured to a dark grey color in 15-24 hours. Once cured, it can be shaped, tapped, filed, sanded and drilled and will retain its strength above or below the waters' surface. MarineWeld has a 1:1 mixing ratio and tensile strength of 3960 PSI. J-B Weld will not adhere or bond well to any flexible rubber surface, leather, vinyl, canvas, polypropylene plastic, and polyethylene plastic. For more information, I would suggest that you contact the JB Weld directly at (903) 885-7696 and they would be in a better position to help you.
