Spectroseal Review

Have you been searching for a durable and convenient way to do your fixings? Tired of sticking your hands with superglue?  You’re reading the right review, because today fixings have been made easy and aesthetically pleasing by UV-glue adhesives. With UV glues, fixings occur in seconds on exposure to UV light which creates a bond of high strength. It can be used for different materials ranging from glass to metals to plastic and what have you? 

With this method of fixings, people are doing away with drilling through glass or using fasteners, nuts and bolts, gluing their hands instead of materials with super glues, that are not just more complex but also unrefined. Bathroom and furniture designers of today can’t seem to be able to do without UV adhesives. DIYers are increasingly adding it to their tool boxes.  

Spectroseal is a UV glue pen recently garnering attention. Read the complete review to learn more. 

What is Spectroseal UV glue pen?

Spectroseal Review

For the folks who like to do it themselves – which is a wonderful trait, there are chances that you have heard of ultraviolet glue pens; the latest most efficient way of gluing. UV glue pens contains the kind of adhesive that requires UV light for curing. This process has been employed by manufacturers in different industries for their large-volume fixings but now it is even getting more popular among individuals in the do-it-yourself bandwagon. 

Spectroseal UV glue is a kind of adhesive that requires a photochemical reaction for fixing. Technically, UV glue is a polymer that relies on exposure to UV light to allow for cross-linking, thus creating a more solid structure at the molecular level. This is in unlike in other adhesives that rely on drying, a process that either takes a longer time or requires exposure to high temperatures. When exposed to UV light, the components of UV adhesives overcome the activation energy needed to trigger cross-linking via photon particles. 

The beautiful thing about Spectroseal UV glue pen that enables clean finishing is that the material stays liquid until exposed to UV-light, this gives the room for realignment until the desired or accurate position is achieved, and then the UV light can then be exposed to the joint and it is glued almost immediately with strong bonds.

The ability to delay the bonding of the UV glue makes it stand out from other solvent-based adhesives which start hardening as they are exposed to the atmosphere and epoxy-based adhesives that start curing as soon as the separate components are mixed together. 

How Does Spectroseal  UV Glue Pen Work? 

Spectroseal UV glue pen utilizes an adhesive that cures only when UV light is exposed to it. Unlike other glues you may know, like the super glues that sticks immediately on exposures to a surface, the adhesive used in Spectroseal UV light pen is a polymer and does not react on exposure but remains liquid until it is exposed to UV light, then it starts to cure.

Moreover, this quality UV light glue device works much faster and is therefore a more efficient way of gluing things together. The process needs a photochemical reaction for the two objects to stick together, and this is where the UV light comes in. You simply place the required amount of the adhesive liquid onto the item needing to be glued, use the UV light for just a few seconds, and there you go – the job is complete! 

The pens are easy to use, very effective, efficient and reasonably priced as well. It is worthy of note that to fully cure and be as hard as possible, it is going to take up to 24 hours after curing has taken place. This doesn’t mean you can’t use the object that you’ve just glued together immediately; it just means the full effect of the UV light won’t be recognized until up to a day after the work is done.

Advantages of UV light curing 

#Quick curing 

An application of UV glue can be cured in about few seconds. The high speed and efficiency achievable with UV glues makes it a technology that is usable for several existing processes and it comes in handy in large-volume industrial applications for a faster and a more durable fixing. A short curing time also lessens quality-related flaws as parts spend less time with wet or unfixed adhesive. 

However, the curing time will always depend on how much adhesive needs to be fixed. Few seconds may not always be the case when the adhesives to be glued is pretty much. However, the curing step is also infinitely adjustable. If a manufacturer wishes to speed up curing, they can simply add more UV lamps or use lamps with higher UV intensity. 

UV adhesives are often the go-to material when manufacturers are looking for the shortest curing time possible. Compared to adhesives that rely on drying, heating, or chemical treatment, the curing process for UV glue is much faster because of its simplicity. 

#Best for all kinds of materials and surfaces 

It is recommended that when bonding or fixing a glass to metal, a strong adhesive is used for a durable gluing to avoid stress due to differential thermal expansion and contraction between the joined particles. This can be easily absorbed by the adhesive and bring about less stress to the glass. This is when UV-adhesives are most necessary since they are designed to be a permanent way of bonding glass and/or other materials.  

Different UV adhesives may come in different forms. The most common ones are epoxy-based, but acrylates are also fairly popular. There are also multi-component adhesives where the second component is a photochemical promoter, which can degrade into free radicals when exposed to UV light. These free radicals then significantly speed up the rate at which the UV glue cures. 

#Flexible workability 

Through some creative chemistry, UV glue starts curing only when exposed to UV light. This means that it remains in liquid form while you work with it under visible light. With this characteristic, an application of UV glue can be modified or adjusted for a virtually indefinite period as long it has not been treated under a UV lamp. This is particularly useful for creatives or for those who apply UV glue with methods that are not perfectly precise.

#Low temperature 

The UV curing process is not dependent on exposure to high temperature and high temperatures, nonetheless has no effect on UV gluing. This is therefore the best option for fixing up parts that have high sensitivity to heat such as fabrics, plastics or metals.  

The fact that UV gluing does not require heat for fixing is an advantage to energy efficiency.  This is a huge advantage in commercial manufacturing for high volume fixing as well as other creative uses. The UV lamp needed for the curing of UV glue consumes much less energy than a heating oven needed to cure a part of the same size. 

#Hazard free 

 Solvent-based adhesives require that the process be done in an area with good ventilation, as the solvents are flammable and typically toxic. 

UV glues present no such dangers or complexities. During the curing process, the UV glue produces no such gaseous byproducts. This means that UV curing poses less of a hazard to workers and is an appropriate option when working in certain environments. 


Curtailed labor is a huge benefit along with reduced set up time and reduced clean up time. An added advantage is the fact that it consumes less space. A UV polymer curing station would carry a small footprint, not taking nearly as much space as an alternative curing station.  Combined with the high yield enjoyed with this process, the efficiency of UV curing pays with a quick return on investment. 

#Exceptional quality  

Exceptional quality is one of the biggest benefits realized with UV glue fixing over other methods. The other methods such as the solvent-based ones that require drying undergoes evaporation in the process leading to a loss of volume  or thickness but that is never the case with UV gluing process. This is why it retains good quality. The more consistent UV curing process also means reduced scrap, which is another goal for improved quality. 

What’s more! UV glues are scratch resistant. UV glue curing provides an unbreakable bond, with improved part visual appeal and functionality.   All of this happens with an environmentally friendly process and no harsh chemicals. 

How to use Spectroseal 

Using the Spectroseal UV glue pen is not technical. It only require you to get the surface cleaned and dried, then first apply a thin layer of the glue to the surfaces you want to cure and squeeze them together. Shine the  UV light on the glue for about three seconds, you can proceed to add more of the adhesive if you want a thicker layer and then shine the UV light again. You can then proceed with your other finishing if you have any left. Whether that is painting, decorating, or just setting it out on the counter somewhere, you are definitely good to go.

Here is the step-by-step guide; 

Step 1: Before applying the Spectroseal UV adhesive, the surface to be bonded must be attended. The surfaces should be kept dry and free of any kind of grease or dust by using pure ethanol and a clean piece of linen to clean. You should keep in mind that it’s advisable for every smooth surface to be roughened in order for the adhesive to develop its adhesive properties optimally. 

Step 2: After cleaning, you can then apply the adhesive. Keep in mind that it can be applied in several layers to fill up slots and holes and for a more strong bond depending on what you’re fixing. Also, to achieve better adhesion, you can first fix the surface by applying a thin layer of adhesive. Then apply a second, denser layer to optimize the adhesive properties. 

Step 3: After you have applied the Spectroseal UV adhesive, you can merge the surfaces and expose the UV light to let the adhesive for curing to take place. If the light does not reach the adhesive everywhere, press the surfaces firmly together for at least thirty seconds. 

Moreover, after curing finishing can be applied to the bond, such as grinding, painting, vanishing and what have you? 

If you want to remove the UV adhesive, do so with petroleum ether when the adhesive has not yet cured. You can soak already hardened adhesive with soapy water.

Frequently Asked Questions  (Spectroseal Review)

How does Spectroseal UV glue pen work? 

The Spectroseal UV glue pen produces a bonding polymer that can be squeezed into small, tight or whatever area you wish to apply the liquid adhesive(polymer). Exposure to UV light causes it to hold fast the surfaces together with a strong bond. The UV waves cause a photochemical reaction causing the polymer to harden more or less instantly. 

Can Spectroseal UV glue pen polymer dry without UV light? 

No, it cannot. Spectroseal UV glue pen polymer like every other UV glue pen, require the UV light to harden. This isn’t a bad thing. Comparatively, instant super glues can get stuck on fingers or you may have trouble drying it. Polymers through a UV glue pen dry fast, clean and easy. 

What kind of glue does Spectroseal UV glue pen use? 

Different UV glue pens use different materials, but in all they are polymers. Spectroseal uses a type of polymer. It’s a German-made adhesive that fully cures and bonds in ten seconds with the assistance of LED UV light. 

Is the Spectroseal UV glue pen polymer toxic? 

Every UV glue pen is a little different. Different polymers or bonding materials can be used. Spectroseal uses a non-toxic, odorless, and water-resistant adhesive. Once dry, you get a heat-resistant, completely waterproof bond. Other brands may use toxic glues or have different characteristics. 

Why are UV glue pens used? 

UV glue pens deliver abundance of usefulness, involving the fact that they require far less time to produce a hardened bonding than other methods. In relation to drying or chemical exposure, there is no comparison. UV glue pens surpass in operation, efficiency, and precision in direction. 

What are the most popular ways to use Spectroseal UV glue pen? 

UV glue fixing is used for a wide variation of objectives, ranging from home use to commercial applications.

Spectroseal Customers’ Reviews  

I have not come across any Spectroseal customer with a negative testimony of this product. Everyone has something positive to say about this product. It is highly recommended and it’s as a matter of fact, stealing shows in the market as regards UV glue pen fixing. Below are what some customers had to say about Spectroseal; 

“Crazy new little gadget that can replace your problems with crazy glue. Easy to apply and the little blue light really works. Plus you don’t have your fingers stuck together!” 

“Repaired a Mickey Mouse engraved wine glass that I was going to try super glue on figuring it was a lost cause. I really is just a few seconds till done. 
And, to somewhat paraphrase, “Sticks to what you’re working on and not to your fingers!” 
I can see using this to repair a windshield chip too.” 

“I have used this before so it wasn’t a surprise to me but this is not superglue or sticky at all. It is a gel that you harden with the UV light it comes with. It works really well and creates a strong bond but the “glue” must be visible to the light for it to harden. I have used it on ceramics, metal, wood, and even a rain jacket and it works great, but you can see some of clear plastic it creates. Very handy for the right project”  

“We have never tried a UV bonding product before but we are happy we chose this one because it worked so well. My wife has a crafting business and she uses allot of plastic items that could not be fixed with traditional glues and epoxy very well. She was able to bond two plastic frames together well and is finding more and more items that she thought would need to be replaced. It has become a savior.” 

Understanding the Science behind UV light curing 

All glues are liquids that harden to hold materials together when dried. Made with polyvinyl acetate (PVA) emulsions, most glues we use are synthetic adhesives created for multiple purposes. 

UV glue is a polymer, often in liquid silicone form, that dries clear when exposed to UV light in a process called curing. Curing takes place when liquid is changed into solid in a chemical reaction called cross-linking. The UV wavelength – between 240 nanometer (nm) and 270 nm, and 350nm and 380 nm – is a catalyst for a photochemical reaction which causes the polymer to harden in a crisscross network. 

Due to the fact that the photon energy needed to strengthen the glue occurs only within the UV range, exposure to ordinary light will not activate the glue. UV glues are often made of a blend of liquid polymer resins and a component called a photochemical promoter. The promoter degrades into free radicals when UV light hits it. This, in turn, causes the resin in the glue to react quickly and increase in strength. 

UV glue is widely used in industrial settings ranging from munitions to decorative and art glass industries but particularly on electronic equipment, especially on the touch panels of smart devices. 

UV glue can be used on almost any substrate, bonding plastic, glass, metal or wood as well as glass to glass, or any other variation of materials. As such, it can bond different materials together. 

Conclusion (Spectroseal Review)

There are various purposes for utilizing uv light adhesives . It is essentially a very strong adhesive that will form an incredibly strong bond whenever there is UV light put on it.  No matter what it is, the stronger the UV rays, the quicker the adhesive will dry and the stronger of a bond it will form. Spectroseal glue pen is a trusted product in the market with quality features and recommendations.
