Bob Smith Industries BSI-203H Mid-Cure™ Epoxy - 4.5 oz. Combined, Light Amber - 15-Minute Working Time Adhesive for Wood, Metal, Fiberglass, Crafts & Repairs

I chose the No.203 epoxy to assemble golf clubs and have used the product numerous times over the past three years. It is significantly more flexible than other epoxies. This makes it an excellent choice to attach heads to shafts and to fix an extender in the butt end of a shaft. Another feature of No. 203 is that it has a lower melting point than other epoxies. This is particularly useful when removing a head from a graphite shaft. With No. 203, I am able to use an electric heat gun instead of a propane torch to heat the hosel or adapter. This minimizes the chance of damaging the paint on a club head or distorting an adjustable adapter. Many DYI's who work on golf clubs use the hardest epoxies with high melting points they can find. I've worked on clubs in which the original J-B Weld was used to hold the head to the shaft. When such an epoxy is used, it is nearly impossible to remove the head without damaging the paint and, most often, without damaging the graphite shaft, which are, themselves, made of graphite cloth saturated with an epoxy-like resin. When the graphite shaft is overheated while removing the head, it is destroyed. If you work on golf clubs, you will have noticed that many manufacturers are now using an adhesive with a low melting point similar to No. 203. In particular, TaylorMade is using something which never seems to completely harden and remains somewhat "gummy". When I noticed this three or four years ago, I searched for something similar and found BSI-203. While it is not the same as the adhesive used by TM, it is somewhat flexible and the lower melting point makes it easier to remove a head. I did have one failure where the head came loose when playing. However, I attribute this failure to poor work on my part, either by not having mixed equal parts of epoxy and hardener or by moving the position of the head on the shaft while it was setting up.

Best Epoxy I've used. It always does the job in keeping things together and best of all, it never dries as the epoxy and hardener bottles are separate with their own caps. The syringe type hardens and becomes trash if not used for a long time, but these last a long time (probably forever).

Excellent quality, easy to use. exceptionally strong bond.

Love this product. The best so far

Top notch this proxy works excellent holds really well

This epoxy works well. It adheres, sets hard and strong, and does exactly what it's supposed to do. I like that it comes in two separate bottles with caps. If you close everything up this product will last over repeated uses. Huge upgrade over the usual hardware store epoxy that comes in the split tube. Why did I deduct a star? My understanding is that I should have 15 minutes to work. But that's not the case. The product starts getting warm at about 6 minutes. That's a warning that time is running out. By 7 minutes it's quite warm and starting to clump, and by 8 minutes it's like hard rubber and you're done. The first time I tried this product I wasted half of what I'd squeezed out due to this issue. Now I know. Watch the time carefully and make only as much as you know you can use in 8 or so minutes. You can always make more later. Good stuff. Just important to know what you're getting yourself into. I will try the slow cure next time.

Used to attach a knife blade to a new handle. Worked as planned.

Excellent Epoxy. Much better pricing than the syringes. I love that it's a 15 min. setting and not a fast setting 5 min. formula, it gives you some time to get everything lined up before it hardens.

Works well cures fast.

I have used this 15 Minute Mid Cure Epoxy before with success. This recent purchase was a replacement as one of two components had become rather too stiff to easily squeeze out of the bottle. Still mixed and glued OK though.

excellent . great glue.
