UV Glue Loctite 34931 Light Cure Adhesive

UV Glue Loctite 34931 Light Cure Adhesive

The best type of UV glue out there is acrylic, which is true for several reasons, as we will explain in the section below. In terms of our overall number one rated pick for the best UV glue is Loctite 34931 Light Cure Adhesive.

  • Made in the USA
  • Water resistant
  • Dries clear
  • Cures in seconds
  • Ideal for small repairs

There are several reasons why we think that Loctite 34931 Light Cure Adhesive is the best UV glue around, with one of those reasons being that with the right UV lamp, this product cures within seconds, for a tough and long lasting bond.

What is nice is that Loctite 34931 Light Cure Adhesive dries totally clear, so you cannot see it, and it also dries very hard, not tacky like many other UV glues out there. This product is water resistant when cured, as well as very resistant to heat as well, although it is not 100% waterproof.

Keep in mind that Loctite 34931 Light Cure Adhesive can bond glass to metal, plastic to metal, and glass to glass, but it cannot bond metal to metal, which is a bit of a drawback. Other than that, we think that this is a fantastic product to consider.

UV Glue Buying Guide

Before you go out and start buying any old UV glue, there are some important things that you should be aware of.

What is UV Glue and How does it Work?

First of all, UV glue is something quite special, something you may have never heard of before. Well, this is a special type of glue that is based off of either an epoxy resin formula or an acrylic formula, with acrylic usually being the better option. In essence, when it cures, this glue forms a type of hard and permanent plastic that is very hard to remove.

However, this still doesn’t explain where the UV light comes into play. When this type of glue is exposed to UV light, or in other words, UV wavelengths, it acts as a catalyst for a photochemical reaction (a reaction that happens due to UV light), which causes the acrylic or epoxy polymers to harden, and nearly instantly at that. Although you do require a special UV light to use this glue, it does qualify as one of the strongest types out there.

Types of UV Glue

What we mentioned above is that there are two main types of UV glue, those made with an epoxy based resin, and those made with acrylic. So, what’s the difference and what is each one ideal for?

Epoxy Based Resin

First off, we have the epoxy based resin, which does have many desirable features. This stuff cures within seconds when exposed to UV light. This type of glue adheres well to most plastics, glass, and metals. What is nice is that it can cure up to 15 mm deep, which is nice for gap filling and crack repairs, but it does shrink by up to 15% when it cures.

This type of glue usually does have a strong odor, although it disappears once cured, and it usually dries clear and does not yellow over time. There is no post-cure required when using epoxy based resin UV glue. Finally, for shadowed areas, this glue often has secondary cure mechanisms, whether heat or moisture. That said, this type of UV glue is usually not overly resistant to weather and solvents.

Acrylic

The second type of UV glue is the acrylic variety, and it is often the preferred type. This type of UV glue features good adhesion to metal and glass, as well as certain types of plastic. What is beneficial about acrylic UV glue is that it barely shrinks as it cures, and it is very resistant to chemicals, heat, and water.

This is why it is preferred. That said, this type of glue may take up to two minutes to dry, it is often a bit yellow and may also yellow over time, and it may require some post-curing with heat for added durability.

How to Use UV Glue

Using UV glue is actually very easy. Follow the steps as outlined below.

  • Make sure that the area is clean. Wash and dry the area if necessary. It should be free of all dirt and totally dry.
  • Apply the UV glue as instructed on the product.
  • If filling a gap, just fill it, and if repairing something, make sure to hold the two pieces together.
  • Once you have applied the glue, us the UV light pen to cure it.

For additional information on how to use UV glue the right way, take a look at the video which we have included here.

Safety Tips

  • UV rays can be harmful to the skin and eyes. Therefore, wear sunglasses that have a high UV rating, and also wear long sleeves and gloves, both to keep the UV off of your skin and to keep the glue off of your skin as well.
  • Always work in a well-ventilated area, as this type of glue can have very strong odors.
  • Always make sure to never get any on your fingers, especially when using the UV light, because this glue can bond to your skin.
