What to Look for Before Buying Plastic Glue?

Okay, you now have got a vivid idea about what are some of the strongest glue brands. If you can’t figure out one to hanker after, here’re some pro-tips to make it easier for you.

The Bonding Material

For you, plastic, maybe just plastic. But for the producers of adhesives, the plastic has different names. You can’t use a single adhesive on every single plastic-type. There are soft and hard plastics that need different gums to join.

What you can do is simply go through the reviews of specs of the product. You can easily find if it supports the type of plastic you are trying to apply it to.

Drying Time

The next thing you need to consider is the drying time. When you apply glue to a surface, It may take from half an hour to about a day before it settles down. If you have no problem with waiting for a long time, that shouldn’t be an issue for you.

But many a time, we may need a quick fix that can’t allow us to wait. That’s when you need to consider a gum type that dries up faster.

Thickness of Glue

There are generally three types of adhesives, depending on the thickness. The thickest gum will take a longer time to set and is best suited for hard plastics. It also has the least run-on amount.

The ones with medium thickness come with a medium layer of gum that requires a little bit less time to set compared to the thickest ones.

On the other hand, the thin adhesive takes the least time to set and is applicable to soft plastics, in most cases.

So you need to choose according to your necessity.

Sealer Cap

Although a sealer cap may seem to be a part just to seal off the head of the tube, it does way more than that. It makes sure that the glue on the tip of the nozzle doesn’t get dried up by coming in contact with the air.

So make sure you get a tube with a perfect sealer cap.

Frequently Asked Questions

Q: What type of glue should be used for plastic?

Ans: It depends on how strong you want the bonding to be. There are a number of gum types dedicated to different strength in bonding. Find out your need and get one accordingly.

Q: Can you bond plastic to wood?

Ans: Yes. If you are using a fixative that has great tensile strength, you can easily bond plastic to wood.

Q: How do I keep the glue fresh in the pack?

Ans: Close the lid of the pack tightly after every use to make sure the adhesive in the tube doesn’t dry up.

Q: Do I need an accelerator?

Ans: If you need a bit of positioning after you have applied gum to a surface, only then you may need an accelerator. Otherwise, it is optional.

Q: What to do if fingers get stuck with superglue?

Ans: Just soak that area in nail polish liquid. After it de-bonds, just rinse it with water. Alternatively, you can use soapy water and warm water, as well.
