Smooth-On A4 Metalset "Military Grade" Epoxy Adhesives - 11 Oz. Tube - MMM-A-1754

Metalset A4 is a powerful epoxy adhesive that has become the standard for all branches of the U.S. Military as well as with every major airline and auto manufacturer in the world. It has been used for diverse purposes from repairing bullet holes in helicopters on the battlefields of Viet Nam to patching leaks in car gas tanks. A4 is used for hundreds of industrial bonding applications and offers excellent adhesion to porous and non-porous surfaces. It can be applied to vertical surfaces without sagging and cures overnight with negligible shrinkage. Once cured, A4 offers good machining qualities (sanding, drilling, tapping) and resists alkalies, dilute acids and solvents. Applications include stopping leaks in pipes, valves and tanks and repairing other metal surfaces. A4 can bond dissimilar surfaces, anchor bolts in wood and concrete, and be used as a filler to repair joints and dents
