Introduction to Adhesive Dots
There are a lot of good hot glue dots out there, and they’re one of the most useful. glue dots, or glue “spots,” are small, round dabs of heat-sensitive glue. They are often called glue “spots.” In this case, they are applied to a surface that has been coated. This way, they can be easily removed and used on many different surfaces. People don’t have to worry about glue dots because they stick right away. This means they don’t have to worry about dangerous odors, messy liquid hot melt adhesives, or residue left behind by film, tape, and webbing.
However, they still have the same range of applications as hot melt, from production lines to mailing materials. We have a lot of different kinds of glue dots, so you can always find what you need for your project. These are the six biggest mistakes to avoid when you use your glue spots to make sure you get the application you want to use them for.
1. Adhering to Dirty Surfaces
To get the best possible bond, your substrates need to be free of moisture, oil, dust, and other things that could get in the way. Use clean and dry surfaces for your dots to be stuck on before you do it!
2. Using the Wrong Size Dot
Because the size of your glue dot might seem like a simple choice, it’s not that simple. It takes more thought than that. Your choice should depend on the size of the surface area you’re going to be bonding together. There is a link between how much surface contact there is and how strong the bond is. There are a lot of things to think about when you decide whether to use 34 inch dots or 12 inch dots. When you choose the right-sized hot melt adhesive dots, you’ll be able to place them in the right places so that your money is spent more efficiently.
3. Applying Dots in Harsh Environments
A lot of stress is put on adhesives when they are exposed to extreme heat, cold, or wet. Glue dots are more likely to fail in these types of environments because they’re applied in a hardened state instead of having a chance to bond after they’re applied through processes like heating and dry. For example, if the materials you’re bonding are going to be exposed to a harsh environment or your application fails and is very important, you might want to think about using a more secure hot melt.
4. Keeping Your Glue Dots on the Shelf Too Long
Hot melt adhesive dots don’t break down over time, and they don’t fall apart. However, because they’re already in their final, sticky state instead of in a container or a hardened pre-melted form, they can get dirty more easily. To make sure the glue stays put, we suggest replacing the glue dots after 18 months and keeping them in the cleanest, driest place possible.
5. Choosing the Wrong Profile
“Profile” is the thickness of your glue dot from top to bottom. lower profile: thin or flat, higher profile: thicker and more full There are a lot of different types of low-profile dots, but they work best on very smooth, flat surfaces that already fit together tightly before any glue is used. Dots that are thicker and have a higher profile are good for surfaces that are concave, have curves, or are otherwise shaped in a different way.
6. Choosing the Wrong Tack
A way to describe how sticky something is called “tack,” and getting this right is very important when it comes to hot melt glue dots. Tack measurements start at a low level, which means the adhesive can be removed. Tack levels go up until they reach super-high tack, where the bond is thought to be long-term.
low-tack glue would be best for something like a credit card mailer, because the glue can be removed. The best glue spot for things like electronics and appliances is one that has a lot of tack but isn’t very noticeable.
