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.

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 5020 PSI.
