SUMMARY

The discussion highlights the fundamental differences between ordinary epoxy adhesives and steel epoxy adhesives, specifically in their composition and application for steel materials. Ordinary epoxy adhesives lack steel particles, while steel epoxy adhesives, such as "JB Weld," contain steel, enhancing their bonding capabilities with ferrous materials. Users have noted that steel epoxy can exhibit properties similar to metal, such as magnetic attraction, due to its steel content. This distinction is crucial for applications requiring strong adhesion to steel surfaces.

PREREQUISITES
  • Understanding of epoxy adhesive chemistry
  • Familiarity with steel material properties
  • Knowledge of adhesive application techniques
  • Basic awareness of ferrous versus non-ferrous materials
NEXT STEPS
  • Research the formulation and properties of "JB Weld" steel epoxy
  • Explore the applications of steel epoxy adhesives in industrial settings
  • Learn about the curing process and performance characteristics of epoxy adhesives
  • Investigate other brands and types of steel epoxy adhesives available in the market
USEFUL FOR

This discussion is beneficial for engineers, DIY enthusiasts, and professionals in manufacturing or construction who require strong adhesive solutions for steel materials.

how is ordinary epoxy (A + B) adhesive differed to steel epoxy (A + B) adhesive in so far as steel is concerned?

Uh ... one has steel and the other doesn't?

I was quite surprised when I found out that there even IS such a thing as steel epoxy but I had been using one for years called "JB Weld". I found out because I used it to glue a magnet to a flashlight and damned if it didn't flow along the magnet just as thought it was weakly ferrous, so I checked the ingredients and yep, it has steel in it. Regular old clear epoxies don't.

Just saw this video on Facebook -- strange! (Not JB Weld, but still)...
