What Is UV Glue And How Does It Work?

UV glue is essentially a unique adhesive that is ideal for an epoxy resin or acrylic base. It is a polymer that works by being exposed to UV light that crosslinks and creates a solid bond at a molecular level.

As compared to adhesives that require a drying time, UV glues may require a lot longer time or a significant exposure to higher temperatures. As a rule of thumb, the higher the temperature, the faster the curing process. The light source can be anything from natural sunlight, LED lights, or UV gas discharge lamps.

Let’s now take a look at the best UV glues you can buy.

The types of UV glues differ based on their curing mechanisms and not necessarily their texture. Let us check out the most common types of UV glues in the next section.

Types Of UV Glues

  1. Heat Cured UV Adhesive: As the name suggests, this type of UV glue uses heat to allow high-speed surface mounts on polycarbonate boards.
  2. Moisture-cured UV Adhesive: This is used for a high-speed, conformal coating onto a printed circuit board and protect its components. This enables curing in the shadowed areas as well.
  3. Anaerobic UV Sealant: This is used by manufacturers for quick and effortless assembling of parts. The shadow cure areas then proceed to cure anaerobically to give permanent, long-lasting, and high strength bonds that are resistant to chemical and environmental anomalies.

Here are a few important safety tips while using UV glues.

Safety Tips For Using UV Glues

UV light, even though good for the curing of the glue, may end up being harmful to you. So, using a proper PPE, including gloves, lab coats, face mask, and safety goggles, is imperative when handling this kind of an adhesive.

Do not touch the UV light equipment directly during the curing process as it may reach higher temperatures and cause severe burns. Wait for 15 minutes before you pack up UV lamp or torch.

Ensure appropriate ventilation when working with UV glue. Lamps or lights that are not ozone-free may end up causing claustrophobia.

UV glues can be a great alternative to regular adhesives when you want strong, permanent, and durable results. Keep the points mentioned in the article in mind and pick a suitable glue from the above list. Get started on your next DIY project!
