## Description

Devcon Plastic Steel Epoxy is a two-part, high strength, cold-welding epoxy for use on all types of metal repairs. Non-flammable and water-resistant, this epoxy contains a steel alloy that will not rust. Fills holes and repairs cracks in broken furniture, tools, appliances, toys, cars and more. Dries to a dark gray color, and once fully cured, it can be drilled, threaded, machined or filled. Bonds all metals including steel, stainless steel, aluminum, brass, iron, pewter, and copper with a tensile strength of 2500 PSI. Only mix the amount of hardener and resin together that can be used within the handling time, and always mix equal portions of the hardener and resin thoroughly together in order for this product to cure properly. Epoxies are generally not recommended for long term exposure to chemicals and solvents. Temperature Range: 200°F constant; 250°F intermittent.

Review: As a hobby machinist, I had chucked an end mill into the collet and failed to tighten it enough apparently. I was blind milling a very long and deep pocket in a bar or steel clamped on top of a sacrificial piece of steel on the bed. Started cutting with the coolant flowing nicely. Everything was going well until I felt a vibration. The collet had worked loose. The end mill had dropped right INTO the mill bed. Starting from zero at 5/8" diameter to about and 1/8" deep at almost four inches long divot. GRRRRR!!!!! Asked some friends on a gun form what to do. This product was the answer. Did it fill in my goof to where the machine was fully useable? Provided I don't try to make that small area fully support a small, clamped work piece, OH YES!!! Cleaned the coolant, swarf and oil out. swabbed and blew it out with the air compressor and let it dry Did the same with a small amount of acetone, let it dry and masked off the area. Worked a nice, mounded blob into the rut and let it dry overnight. Very carefully filed it down flush with a flat, bastard mill file. Checked the finished height with a scraper mounted to the quill. Good to go. lightly touched it over with fine Scotchbright pad to smooth and blend, then back to the races! I'm still a bit embarrassed, but the mill is OK. :) . JB Weld would have been probably just as good, but thought I'd give this stuff a chance. No regrets. Great product.
Review: Quality, dries quick quality, sticks on like plastic steel. It saved me $480 sticking a part together like new.

## Questions & Answers

**Q: Will this bond a plastic hook to a wall that is made of frp panels? also what is the maximum weight it can hold up? thank you.**
A: This video test several epoxy brands and does show a hanging weight test.  Devcon did well against others but I'd imagine another solution would work better. https://www.youtube.com/watch?v=XObmZIbHOzY

**Q: Would this work on a large polystone statue?**
A: If the material is semi-porous  it should.  It must be cleaned of oils and dirt before applying.   Allow to set up for 24 hours before moving.   Tensile strength for this material is about 25,000 ibs.

**Q: Will this epoxy take cold blueing?**
A: doubt it .

**Q: can I use this to fill a small hole caused by rust near the drain in my metal tub?**
A: Yes. It should work fine for that. Make sure you prepare the tub surface  first and let it set for the recommended amount of  time before using the tub.

*by J***E on 17 November 2019*

I got acquainted with this product where I used to work. I already knew of the super bonding properties of this product. I used it to attach the knob on my oxygen control on my acetylene/oxygen outfit due to the splines in the knob were stripped out and the knob would just spin and not do anything. Now it works perfectly. Great product !
