Different Types Of Plastic Glues

Cyanoacrylate Adhesives

Popularly known as super glue, these adhesives are derived from Cyanoaceylic acid. They form a quick and durable bond between a variety of surfaces through a fast polymerization process, with the help of a catalyst.

For Cyanoacrylate adhesives, the catalyst is moisture. The acrylic monomer (cyanoacrylate) of the adhesive turns into solid plastic when triggered by the catalyst (moisture). This phenomenon happens almost instantly, and once formed, creates a sufficiently strong bond.

UV-Activated Adhesives

These types of adhesives are activated by UV lights. The adhesive stays in a liquid form until it is exposed to a certain range of UV (e.g. 365-nanometer/395-nanometer). These products are generally equipped with a penlight to generate and precisely focus the UV onto the liquid.

UV-activated adhesives offer superior flexibility than other types of glues.

Contact/Cement Adhesives

Cement adhesives use polymers that contain the ability to bond even after they are dried through a process called auto-adhesion. Thus, they provide better impact resistance, can be molded into certain shapes (e.g. for laminating), and is more effective in bonding surfaces that liquids can’t penetrate.

They are largely used to assemble automobile parts, laying floor tiles, and setting counter-tops at kitchens and washrooms.

Polyurethane Adhesives

These adhesives are constructed using either a polyester or polyether-based formula. They are praised to be one of the most flexible adhesives, as they can be used for a variety of purposes, allowing you to bond a wide range of materials (e.g. bonding films, SMC, etc.)

How To Choose The Right Glue For Plastic To Plastic

Chemical Structure

The chemical anatomy of a glue plays an important part in determining whether the product is compatible with your intended use.

For example, super glues use a derivation of Cyanoaceylic acid, thus they are also known as Cyanoacrylate adhesives. They have the ability to bond a wide variety of surfaces, ranging from plastic to metal. However, they are less flexible than a UV-activated adhesive or a contact/cement adhesive.

So, for general use, super glues will work just fine. But if you plan to use a glue for assembling a model car or crafting a showpiece, adhesives with more flexibility will serve you better.

Construction Of The Container

We always recommend making sure that your glue has an external cap to prevent spillage and auto evaporation, along with a self-piercing feature (e.g. an attached metal pin) that doesn’t allow the glue to get clogged up.

You should also ensure that the nozzle has an ergonomic design which allows you to safely and precisely apply the element.

Pro tip: choose a product that comes with extra nozzles as they tend to get jammed/clogged quite often.

If you buy a UV-activated glue, make sure the package contains a pen light. Otherwise, it’ll be difficult for you to locate the accurate range of UV that can provide the finest output.

Compatible Surface

Always check if the glue you’re purchasing is compatible with the surface you intend to use it on.

For example, some super glues perform well on tough plastics, metal, rubber, PVC leather, fabrics, etc. Yet may not function well on surfaces like polypropylene and Teflon.

Or, in terms of laying floor tiles or installing countertops, a cement adhesive will perform better than a super glue or a UV-activated glue.

Resistance Features

A major indicator to help you recognize the best glue for gluing plastic to plastic is the product’s level of resistance against harmful factors.

Your carefully fixed china white may fall apart after a wash if you use a glue without water resistance. Or, a laboriously built model car can suddenly break if you don’t apply an impact resistant glue.

So, we recommend buying glues that provide the necessary resistances (e.g. against water, impact, temperature, clamping, etc.) for your intended use.

Extra Features

If you desire a flawless fixing job, make sure that the glue has a clear dry feature. This way you can avoid disrupting the symmetry of the reassembled material.

Also, buying an adhesive with a quick-dry feature is useful as it speeds up the bonding time. You can use an accelerator to quicken the bonding time and use primer to increase bonding strength as well.

Final Words

“We all make mistakes, but what matters is how we go back and fix them.”

This famous quote can make us all feel a little better. It reminds us that even though mistakes can be made, there’s always a chance to fix them. But how do we do that?

Well, you can always use a super glue.

Which is why, in this guide we have discussed the crowning qualities that will help you choose the best plastic to plastic glue from a market saturated with mediocre alternatives.

Let’s hope we can fix the mistakes we made in life, along with fixing all our favorite plastic accessories.
