How To Use CA Glue? Everything You Need to Know
You’ve certainly heard of cyanoacrylate glue or CA glue before, just in a different name. This is the very same substance we call super or crazy glue.
It is one of the most useful adhesives on the market, especially because it is the fastest-setting type of glue.
With the instant adhesive market expected to hit $3.14 billion by the year 2026, it’s no wonder that CA glue is being widely purchased around the globe. Let’s learn a little about how to use CA glue & what it is?
What Makes CA Glue Different?
CA glue is nothing like your standard epoxy adhesive. As we mentioned before, this glue sets much faster than any other type of glue. This is why it is favored for industrial use for time is a valuable asset.
What makes this glue so fast? Well, simply put, it reacts with the moisture on the surface of the materials you are working with, and creates strong chemical bonds between the surfaces you apply them to.
This is much faster than the evaporation process that occurs for epoxy glue. It’s even faster than UV glue and the heated glue used in glue guns.
Additionally, there is a reason why it’s earned the nickname super glue. It is really strong and creates a bond that is entirely waterproof. You must be wondering, “what’s the catch?”
For starters, It’s not going to work on all surfaces. If the surfaces you are dealing with do not have any moisture, the glue may not be able to make those bonding happen.
On top of that, it is extremely reactive with our skins since it has so much moisture and so, it gets on your hands, and you will have a hard time getting rid of it.
Lastly, due to its quick-drying nature, it is not ideal for a lot of uses that need time and precision.
These cons may limit its usage but that doesn’t mean it still isn’t a very convenient substance to have around the house.
Different Types Of CA Glue
Before we talk about how to use CA glue, it is important to take a look at the types of CA glue you can purchase as each type serves a different purpose. Generally, there are three types of CA glue: thin, medium, and thick.
1. Uses For Thin CA Glue
This type of CA glue is, as the name suggests, the thinnest form of the substance. Due to its low viscosity, it resembles water and that makes it ideal for tasks that need minimal thickness.
Such tasks include applying a finishing or coating to add some gloss to an item or sneak into small crevices. The low thickness makes this glue weaker than the other types so it won’t work that well for bonding two items.
It is important to note that this glue dries really quickly, literally within 5 seconds. You need to work quickly.
2. Uses For Medium CA Glue
If the thin variant is a little too runny or dries a little too quickly for your application, this might do the trick. In fact, this is the glue to use for most purposes.
The viscosity is at that perfect level where it doesn’t slip past the surface. It comes out in a semi-liquid form. This makes it the best option if you need a lot of control.
The strength is medium, meaning that it isn’t very powerful but it should do a decent job keeping your glued items together.
Additionally, the approximate 20 second drying period means that you have some time to work with it before it sets. You may have to wait longer for a large amount of glue.
The ideal use for this type of glue is to solidify two tight-fitting items into one hefty structure. The glue can strengthen the bond and make sure that the structure doesn’t collapse. It is also good for filling in cracks.
3. Uses For Thick CA Glue
Last but certainly not least, this is the thickest and strongest variety of this glue. Because of this, it is really hard to work with and takes a while to dry.
We don’t just call it thick for no reason, it is quite dense. It will not find its way through any small opening or drip in any way. It is almost paste-like due to its thickness.
The lack of mobility is made up for by its impressive hold. This is the glue ideal if you are looking to permanently bond to items.
Wait around 50 seconds and your items are as good as sealed for life. Again, the time will vary according to how much glue you are using.
How To Use CA Glue? 3 Steps Explained
Now that you know which glue you have to use for what purpose, let’s move on to a short guide on how to use the substance for any purpose.
Step 1: Apply The Glue
You need to start by applying a reasonable amount of CA glue to the surface you are planning to work on. The amount varies greatly depending on the purpose. For example, if you are looking to apply a shiny finish to a wooden project, you’ll need a lot of thin CA glue.
In sharp contrast, you would need very little thick CA glue to mend together two pieces of glass.
Step 2: Wait For It To Dry
After you’ve applied the glue, you need to let it sit for some time for it to set. No matter which glue you use, it won’t take very long. Even if you use large amounts of thick CA glue, it shouldn’t take over 2 minutes for the magic to happen.
If you need more speed, however, you are always welcome to apply an accelerator. This is a spray that speeds up the drying process significantly.
Step 3: Inspect
The last step is not a necessary one but it is highly recommended. After you’re done, take a look at the finished process and see if the results are exactly to your liking. If they aren’t, try using more glue or opt for a different glue.
Tips And Cautions When Using CA Glue
While CA glue can make your life easier, there are a lot of things that can go wrong if you aren’t careful with this substance.
1. Make Sure It Is The Right Glue For You
First and foremost, this will not work on all surfaces and it isn’t ideal for all purposes. Common sense goes a long way here. For instance, you don’t need it to glue two pieces of paper.
2. Short Shelf-Life
Do not buy this stuff in bulk. It is quite expensive and it doesn’t last very long, a year or two at most. Make sure you store it in a cool space, preferably 4 degrees Celsius or lower, to maximize its shelf life.
3. Take Protective Measures
As we said before, it is extremely reactive with skin so make sure that you glove up and use this substance with care. In the event that it gets on your skin, use some acetone to get it off. Needless to say, it is not a child-friendly product.
4. Opt For High-Quality Brands
Lastly, make sure you don’t buy cheap or low-quality CA glue. Not only are they not reliable but the chemical composition may be harmful to your skin. Go for the big brands such as Infinity Bond and Permabond.
All in all, CA glue is an excellent adhesive if you are looking for glue that is easy to use and dries really quickly. This product has some household uses, but it is also one of the most widely used adhesives for industrial uses.
Nonetheless, it can be a quick fix for a lot of hiccups in the common home. We hope this article helped you understand what is CA glue and how to use it in your own home or for industrial purposes.
