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 Safety- use in a properly ventilated area. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Store and use material at room temperature (73 F/ 23 C). This product has a limited shelf life and should be used as soon as possible. Step 1: Preparation: A clean, dry surface is essential for successful adhesive bonding. Porous materials are simple to bond, provided they are dry. The surface should be sanded until clean followed by wiping surface with solvent (acetone, MEK, mineral spirits). Let solvent evaporate fully before applying A4. Non-porous surfaces (metals, plastics,coated woods) should be sanded, sandblasted or chemically etched. If sanding or sandblasting, follow with solvent wash. Let solvent evaporated fully. Epoxy adhesives do not perform well on metals such as nickel, chromium, tin or zinc or on soft thermoplastics like polyethylene. Step 2: Measuring and Mixing: Metalset A4 is mixed one part A to one part B by weight or volume. If dispensing from tubes, squeeze out equal amounts from each tube. Try to be as accurate as possible. Mix thoroughly with clean stirring stick for at least 3 minutes until components are blended to a uniform, light cray color. Step 3: Applying: Apply to substrate surface. Metalset A4 will cure in 16 hours at room temp (73 F/ 23 C) Applying mild heat will cure A4 faster (150 F/ 65 C) for 2 hours. Step 4: Post Curing: After A4 has cured at room temperature, heating the epoxy to 150 F for 4 to 8 hours will increase physical properties and performance. Let cool to room temperature before moving bonded substrates, machining, etc. Overall Rating for Smooth On METALSET A4 - 6 Oz. Tube - 8040-01-298-2978 | (based on 2 reviews) |  |
Metal SetBy Rudy from Citrus Springs Florida on August 11, 2011 I worked in a fossil fuel power plant for 25 years and used Metal Set to repair gouges on tube sheets to prevent steam leaks to broken bolt on tabs on motors. This epoxy can be machined and tapped and used very thin to keep parts within clearances. In other words, this amazing stuff kept us running and on line. I am retired from the plants and am now in the custom handmade knife business and use metal set to epoxy on knife handles. It takes a grinder to remove the handle after it has set. This stuff is the best I have found.I would recommend this item to a friend.METASET A4By RABELLO JC on January 8, 2010
