How to Avoid Bubbles in Resin

WHY ARE BUBBLES A THREAT TO YOUR RESIN ARTWORK?

Bubbles are undesirable in resin products as they make the product both visually unappealing and potentially less robust. 

Even tiny bubbles, especially in large quantities, can make the appearance cloudy or hazy, significantly reducing their transparency. This ruins the intended visual effect, particularly for those resin pieces that desire a glass-like finish with the pressed-flowers aesthetics, be it jewelry, coasters, or keychains. Other than aesthetics and appearance, bubbles are a threat as they make the final piece brittle and prone to cracking or breaking under stress.

If you are a resin business owner, you should be worried about these imperfections as they give an unprofessional appearance and a lack of durability in your offerings.

Starting Right.

2. Mix Slowly and Steadily-

Proper mixing is crucial for minimizing bubbles. When combining the resin and hardener, mix slowly and steadily for 3-4 minutes. Avoid vigorous mixing, which can introduce more air into the mixture. Instead, use a gentle, consistent motion to ensure the components are well combined.

3. Hot Water Treatment-

For some resin projects, placing the resin container in a hot water bath can help release bubbles. Fill a separate container with hot water (around 60°C) and place the resin container into it. The heat from the water can help the trapped air bubbles escape, resulting in the desired clear finish.

Measures to take in the Pouring Stage-

4. Pour Layer by Layer -

For thick casting projects, pouring the resin in layers can help prevent bubbles from forming. This technique allows each layer to settle and release any trapped air before adding the next layer. By doing so, you'll reduce the likelihood of bubbles becoming trapped in the final product.

5. Blow Torch Gun-

A blow torch gun can also be used to remove bubbles from the resin surface. However, exercise caution when using this method, as the flame can be intense. Hold the torch at a safe distance and gently sweep it across the surface to release trapped air.

6. Bubble Remover Spray-

Specialized bubble remover sprays can be applied to the resin surface to help release trapped air. These sprays can be particularly useful for delicate or intricate projects where heat guns or blow torches may not be suitable.

 

By following these steps and using high-quality resin, you'll be well on your way to creating beautiful, bubble-free resin products that showcase your craftsmanship and attention to detail.
