Its medium-high viscosity gap-filling formula adheres to wood, metal, fiberglass, ceramics, and plastics, making it ideal for professional repairs, crafts, and hobby projects requiring precision and durability.

## Description

MID-CURE 15 min. epoxy is used in larger areas where more working time is needed. It is more water resistant and can be used as a substitute for QUIK-CURE in most applications. MID-CURE is our most flexible epoxy and is ideal for gluing to fiberglass surfaces. Allow 45 minutes before handling parts and 2 hours for full strength. Directions in 5 different languages.

Review: Best Epoxy - 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).
Review: flexible and with low melting point - 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.

## Features

- Reliable Medium-Set Bonding: MID-CURE epoxy provides a 15-minute working time and cures in 30-45 minutes, giving you precision control and dependable results on projects large and small.

## Questions & Answers

**Q: How long does it take to dry?**
A: It took 30 minutes not to show fingerprints.  Was still tacky.  Left the parts overnight to dry completely.

**Q: Does this work with aluminum?**
A: Epoxy will stick to  most anything, including Aluminum.  BUT, since metals change "shape" with temperature it may not stick for too long.  So the answer is an official "it depends".

**Q: Is this epoxy flexible?**
A: The manufacturer said:
"MID-CURE is our most flexible epoxy."

**Q: Has anyone used this on fishing rods for repairing a broken rod and sealing the guide thread?**
A: No, straight up it won't work. It will need some form of a splint. So, if you find a tube that just fits over each end of the broken rod, and use the glue to hold the broken ends in the tube, then it will probably work. Or maybe an actual splint lashed to the rod and use the glue to hold the splint and lashing in place. No glue by itself will provide the support you need.
