UV resin is a popular choice for curing glass, but many people struggle to achieve the perfect results they're after. Unlocking the secrets of UV resin can help take your creations to the next level. In this journal, I'll cover everything from the basics of UV resin to advanced techniques for curing glass with precision.

Nitty-gritty details

There are two types of resin. Two-part system Epoxy resin consists of a resin and a hardener. When these two components are mixed together, a chemical reaction occurs that causes the resin to harden and cure.

Second option is a Fast Curing UV Resin can get fully hardened in 40-45 seconds under the UV light or sunlight, surpassing most models of UV resin in the market which does not need to be mixed.

Unlike other types of resin, UV resin cures quickly and efficiently under ultraviolet light.

The curing process is initiated by exposing the resin to UV light, which triggers a photopolymerization reaction. This reaction causes the resin to harden and cure, creating a hard, durable surface. The curing process is affected by several factors, including the intensity and wavelength of the UV light, the thickness of the resin layer, and the temperature and humidity of the surrounding environment.

To achieve the best possible results when curing glass with UV resin, it's important to understand how these factors affect the curing process. By controlling these variables, you can achieve precise, consistent results every time.

Types of Glass Suitable for UV Resin Curing

Not all types of glass are suitable for curing with UV resin. In general, glass that is transparent or translucent works best, as it allows the UV light to penetrate the surface and initiate the curing process. Opaque glass, on the other hand, blocks UV light and prevents the resin from curing properly.

When selecting glass for UV resin curing, it's important to choose high-quality, clear glass that is free from scratches, chips, or other imperfections. Any imperfections in the glass can affect the curing process and result in a less-than-perfect finished product.

  • Borosilicate glass: This type of glass is highly resistant to thermal shock and is often used in laboratory equipment and cookware. It is also suitable for use in UV resin curing due to its optical clarity and high transparency.

  • Fused silica glass: This type of glass is extremely pure and has a high degree of optical clarity, making it ideal for use in UV resin curing.

  • Quartz glass: This type of glass is highly resistant to both thermal shock and chemical corrosion, making it a popular choice for use in high-temperature applications. It is also suitable for use in UV resin curing due to its high transparency and low impurity content.

To cure glass with UV resin, you'll need a few key tools and materials. Here's a list of the essential items you'll need:

  • UV light source: This is the most important tool you'll need for curing glass with UV resin. You can use a UV lamp, a UV flashlight, or even direct sunlight, depending on the size and complexity of your project.

  • UV resin: Choose a high-quality UV resin that is specifically designed for use with glass. Look for a resin that is transparent, self-leveling, and has a low viscosity for best results. (Hardener: The hardener is an essential component of the UV resin curing process. Make sure you choose a hardener that is compatible with your chosen resin.)

  • Mixing cups and stirrers: You'll need these to mix the resin and hardener together before curing.

  • Sandpaper or a polishing tool: Depending on the finish you're looking to achieve, you may need to sand or polish the cured resin surface.

  • Protective gear: As mentioned earlier, it's important to wear gloves and safety goggles when working with UV resin.

  • White spirit / Acetone: dissolves unhardened resin, ideal for cleaning tools and brushes off resin

Tools and Materials Needed for UV Resin Curing

Now that we understand the basics of UV resin curing and have prepared the workspace and gathered all tools and materials, it's time to get started! 

  • Clean the glass surface: Before applying the resin, make sure the glass surface is clean and free from dust, dirt, or other debris. You can use Isopropyl alcohol or rubbing alcohol to clean the surface.

  • Apply the resin to the glass: Use a brush or dropper to apply the resin to the glass surface. Be sure to apply the resin evenly and avoid creating any air bubbles.

  • Cure the resin using UV light: Once you've applied the resin, use the UV light source to cure it. Place the glass under the UV light and allow it to cure for the recommended amount of time. I recommend enclosing the light and the object inside a dark shoe box.

  • Sand or polish the cured resin: Depending on the finish you're looking to achieve, you may need to sand or polish the cured resin surface. Use sandpaper or a polishing tool to achieve the desired effect.

While curing glass with UV resin is a fairly straightforward process, there are some common mistakes that can affect the quality of the finished product. Here are some mistakes to avoid:

  •  Applying too much resin: Applying too much resin can result in the formation of air bubbles or a cloudy, uneven finish.

  • Using the wrong type of glass: Using opaque or low-quality glass can prevent the UV light from penetrating the surface and initiating the curing process.

  • Under-curing or over-curing the resin: It's important to follow the manufacturer's instructions for curing time and intensity to ensure that the resin cures properly.

Here are some frequently asked questions about UV resin curing:

Q: Can I cure UV resin without a UV light source?

A: No, UV resin requires exposure to UV light to cure properly.

Q: How long does it take for UV resin to cure?

A: The curing time depends on several factors, including the intensity of the UV light, the thickness of the resin layer, and the temperature and humidity of the surrounding environment. Follow the manufacturer's instructions for best results.

Q: Can I cure UV resin in direct sunlight?

A: Yes, direct sunlight can be used as a UV light source for curing UV resin.

Q: Can I use a different type of hardener with my UV resin?

A: No, it's important to use a hardener that is specifically designed for use with your chosen UV resin.

Conclusion and Final Thoughts

My preferred option for working with glass is the UV resin that dries quickly. It not only works as an adhesive but also adds a raised texture to the surface of the material. Moreover, I have utilized it to give a beveled edge to sharp glass. It can be removed from the glass surface using a scalpel, which provides me with greater flexibility in creating my designs.
