As a long time user of CA (cyanoacrylic) glue I have developed some methods of use and storage that I want to pass along. The stuff is expensive as glues go and constantly throwing out old hard glue and going to the hardware store for more is a pain. So here is the method of storage to combat that..
Forget the refrigerator storage. It really doesn’t do much good. The catalyst that sets off CA glue is MOISTURE. Keep moisture out of CA and it will last sitting on your bench for years. To do this, I use a large mouth glass jar with a good top that was made to hold liquids. I put the glue in the jar with a package of silica gel to absorb any moisture within the closed jar. Silica gel is what is known as a desiccant which absorbs atmospheric moisture and holds it. Just Google “silica gel” and you can buy it very cheap online in various types of containers. I use an aluminum container that has a spot on the side that changes color when the silica gel is saturated. No need to buy more, just put the container in an oven at a temperature slightly above 212 degrees (F) to drive out the moisture and you are set to go again. After using your CA glue just put it in the jar with the silica gel and screw the cap on tight. I have had large bottles of CA sit on my bench for years like this.
Large bottles of CA tend to have a rather large hole in the applicator end. If you want more control over applying thin CA, get your doctor or pharmacist to give you the needle from a hypodermic syringe. these needles have a pop-off base that plugs onto the CA bottle perfectly. I use a fine cut-off disk in a Dremel tool to trim off the sharp point. Be aware that there are many diameters of needles so pick one that suits you. Yes, the needle will occasionally clog with glue. Simply hold the needle over a butane cigarette lighter flame for about one second and the needle unclogs immediately.
