How UV Curing Epoxy Resin Works

How UV Curing Epoxy Resin Works

The efficiency of UV Curing Epoxy Resin as an adhesive has surely taken many people by storm. It has performed well above the expectations of its critics. This particular adhesive can be referred to as a game changer in the industry.

But as you would rightly suspect, most people don’t understand the chemistry and dynamics of this type of adhesive solution. If you belong to this group, this post is exactly for you.

In this article, you will learn how UV Curing Epoxy Resin works. The more knowledge you have on the subject, the higher your chances of applying it correctly.

What is UV Curing Epoxy Resin?

UV Curing Epoxy Resin has become a familiar adhesive. As we may already know, UV curing is the act of bombarding a resin with UV rays to reduce its curing time by a reasonable time. It derived its name from the ultraviolet light used in the process.


How Does UV Curing Epoxy Resin Work?

Before we begin, I like us to understand that there are UV curable resins and resins that are not UV curable. This distinction is what lays the foundation for our discussion here.

UV Curing Epoxy Resin is made up of oligomers, monomers, photopolymerization activators, as well as other adhesives. When this epoxy resin is exposed to UV rays, the light initiator reacts chemically with independent monomers and oligomers to form a complex chain.

The newly formed chains can be referred to as polymers – a complex product of the simple monomers and oligomers that reacted with the light initiator. The reaction process that births the polymer is known as Photopolymerization Reaction.

As the resin goes through this photopolymerization reaction, it changes from its liquid state to a solid state. It is possible to dry, paint, and bond materials and objects through this process. That is the reason UV curing can be equated to UV coating, UV bonding, UV drying, etc.


How Long Does UV Curing Epoxy Resin Take?

The duration of UV curing epoxy resin is extremely short as far as I know. This is one of the characteristics that has boosted this type of adhesive solution. UV cured epoxy resin will work for a wide range of materials or substrates.

It almost does not matter what you are trying to bond, it just works. UV curable epoxy resin can form reliable bonds on surfaces for much longer than you can expect. The bottom line here is that UV curable epoxy resins only need seconds to form a long-lasting bond.


What’s The Strength of The Bond Produced

Although the curing speed of epoxy resins is super-fast, that does not make it any less reliable as a bond. It bonds excellently with every substrate it comes in contact with. And I am not talking of weak bonds. These bonds can last a lifetime. That is how solid they are.

Manufacturers are adopting this type of adhesive because of the strength of its bonds. Their bond strength makes them cost-effective adhesive solutions.


The Downside of Normal Epoxy Resins

The shift from normal epoxy resins to UV curable epoxy resins has become necessary because of the downsides of the former. One disadvantage of normal epoxy resin is that it takes a long time before it cures. Some of such epoxy resins can take as long as a week to cure.

In such a scenario, it is almost unavoidable to use a large amount of labor. It also implies that the affected materials be kept somewhere safe to enable them to dry properly. This will amount to a higher cost of production.

So, you see the reason why it was not difficult for people to ditch the normal epoxy resins for the UV curable types.


Consider The Best Quality

Virtually all UV curing epoxy resins will output high-quality bonds. That is the idea behind the product. But while high-quality epoxy resins are assured, one needs to be wary of the quality of the bond. Some qualities are definitely going to be better than some.

You should research for companies that are devoted to delivering the best quality UV curable epoxy resins. Take advantage of the many professional suppliers online to create strong bonds for any substrate.


UV Curing Vs Thermal Curing

UV curing is fast becoming the order of the day. UV curing has encouraged a sharp departure from the conventional thermal curing. The reasons why thermal curing is not as popular today are obvious. Thermal means the process needs a lot of heat.

With the heat involved, safety was a problem. Curing precision was also an issue. All those factors made UV curing a preferrable option. One does not need to apply too many technicalities before they cure with UV. It equally offers the individual curing more control over their environment. UV curing has been a progressive technology. I am sure it is far from perfect at the moment. But it is better than thermal curing.


Other Uses of UV Curing

UV curing cannot be compared to any other curing methods because their use is not limited to adhesives. UV curing can also be used for painting and drying. So, you see how they are widely employed in various industries.

Furthermore, UV lights are currently being used for inspection during research and manufacture. Today, there are many real-world products that employ UV tech. There are hundreds of UV applications in different sectors worldwide.


UV Curing Epoxy Resin is the way to go now. If you seek the best quality adhesive solutions, that is what you should go for. In this post, we have learned about the chemistry and formation of epoxy resins. We now understand how UV can make the process better. Also, we have established that UV curing seems to be ahead of any other curing method. That’s why it is getting all the accolades at the moment. Attempting to use normal epoxy resins to bond substrate surfaces is like moving against a huge tide. UV curable epoxy resin is the new trend.
