3M Weld-Thru II is a convenient aerosol coating designed to prevent corrosion between welded metal surfaces. Featuring a zinc base that draws corrosion away from bare metals, it helps prevent costly comebacks due to corrosion at welds. Spray coating applies fast, resists weld spatter common to some weldable primers and dries in as little as 5 minutes, increasing shop efficiency and productivity.Keeping Bonds Strong
By preventing corrosion between welded auto body panels, our 3M™ Weld-Thru II promotes stronger business between your shop and your customers. This coating protects against corrosion where untreated bare metal substrates are welded – its zinc base uses the concept of bimetallic corrosion to keep metal parts from degrading. Welds stay strong, parts and panels don’t corrode and you keep comebacks to a minimum.
Tough on Corrosion, Easy for Welding
3M™ Weld-Thru II also helps keep collision repair shops operating efficiently. Its convenient aerosol can makes it fast and easy to apply, and features an actuator tip that resists plugging even after repeated use. The coating dries in as little as 15 minutes when using a resistance spot welder and as little as 5 minutes for MIG welding, helping technicians work faster and maximizing throughput. The formula also resists weld spatter than can cause burns to technicians or shop equipment.
3M™ Weld-Thru II can also be easily used on non-weld metal surfaces with 3M™ Cavity Wax Plus 08852 and 3M™ Cavity Wax Applicator Wand Kit 08851.
Applying Better Science to Collision Repair
Our 3M™ Weld-Thru II coating is another example of 3M Science. Applied to Life™. It uses the science behind bimetallic, or contact, corrosion to draw rust and other corrosive effects away from untreated bare metal – keeping the bonds strong at the welds, and keeping the bonds strong between your customers and your collision repair business.
