Mercury Flex CA


Mercury Adhesives makes the best CA, Epoxy, and Accelerator right here in the United States and is what I use for my own pens, from $30 Slimlines to those costing hundreds of dollars. Made in America – their cyanoacrylate reactors are in Alpharetta, GA, just north of Atlanta. Ask your current CA supplier where their reactors are located. Also, ask about the warranty for your CA. Mercury’s is simple – it’s unconditionally guaranteed. If there is a problem, They will replace it. Yes, it’s that simple.

Mercury’s Flex CA is designed for pen turners and other wood working. Unlike other brands which use rubber to give their CA flexibility, Mercury Adhesives uses a unique set of ingredients that won’t interfere with that crystal clear finish you’ve come to expect from Mercury CA. Medium Flex is available in 2 oz Bottles.

It has a longer open time and allows you to easily get a smooth coat on the pen blank. Plus, it provides plenty of time when gluing tubes. Mercury Flex CA is designed to be used with accelerator and needs it to cure “instantly”. It gives a flexible finish which can survive abuse that customers do to pens. And, it goes on even smoother, provides better coverage, and helps give you the best finish for your pens and other turnings. Mercury’s Flex CA can be left alone for a matte or satin finish, or it can be buffed & polished up to a glass-like shine. The Medium Flex CA is great for gluing tubes as it resists shock & shear forces much better than regular CA. Naturally, it helps create a fabulous finish that is unrivaled in clarity. It can go from satin to glass – whatever you and your customers want. Remember, Mercury’s Flex CA needs accelerator to begin curing quickly.

​Mercury Adhesives manufactures their CA here in the USA, in Atlanta, GA. It is a medical grade CA that is highly concentrated and the purest premium CA available. For finishing pens, just a drop or two is all that is needed for each coat. There are additional formulations for pen makers. Thin Flex, Medium Flex, Thin Regular, Medium Regular, Odorless, & a unique High Performance that is great for oily wood. Another unique feature isn’t with the CA, but with the bottle. All Mercury CA is packaged in clog free bottles. There are three sealing points within the cap, including a steel pin to help keep the tip clear & open. But, if CA does build up on the tip or cap, just soak it in acetone for little while and it will be good as new.
