Bonding Metals With Hot Melt Glue

ThreeGunsA
Metal is a shiny and non-porous surface, which can be challenging to bond.  Below are a few helpful tips to help you maximize the strength of your gluing application.
Helpful tips:
- Make sure that the hot glue is completely heated in the glue gun.
- Be sure the metal is clean, free of dirt and oils.
- Use mild soapy water to clean the metal, not solvents such as alcohol, acetone, or citrus based cleaners.
- Roughening up the bonding surface will increase adhesion, and give the bond a better “bite” into the surface.
- For metal to metal applications, both metals should be preheated to insure best possible bond. This technique can also be used at any time that the bond does not appear to be holding as well as expected. This may be more evident in colder weather or when the application room temperature is low.
- Allow at least 24 hours before checking the bond.
The three glue formulas that work well for bonding metal are Dent Pulling Glue Sticks, Dura Tac High Strength Glue Sticks, and OmniBond – For Challenging Surfaces.
