Summer Tips For Using Epoxy Resins in 2024

Mar 19, 2024

Epoxy resin is a versatile component commonly used in different crafting and industrial applications. Its ability to create a strong, durable, and glossy finish makes it popular for creating artwork, jewellery, coatings, and more. As the summer of 2024 approaches, it's essential to equip ourselves with the knowledge and techniques to navigate the challenges that high temperatures can cause when working with epoxy resins. Consider joining a resin art workshop to get hands-on experience working with resin in the summer.

In this blog, we will learn crucial tips for effectively using epoxy resins during the summer of 2024. From temperature considerations to storage recommendations and practical strategies for working with epoxy resin in warm weather, we aim to provide valuable insights for beginners and professionals alike. So, let’s get started!

1. Temperature and Humidity Considerations

Temperature and humidity are key factors for success when working with epoxy resins in the summer. Understanding how temperature and humidity affect epoxy resin is important for summer projects. Here are some things to keep in mind:

  • High temperatures can quicken up the curing process, which may lead to problems like shorter working times and faster changes in thickness.
  • On the other hand, low temperatures can slow down the curing process, causing longer drying times.

Ideal Temperature Range

For storing and applying epoxy resins, it's best to keep the temperature in the range of 75°F and 85°F (24°C to 29°C) to get the best results. Here's why:

  • Extreme heat can cause the resin to cure too quickly, making it harder to work with.
  • Extreme cold can cause the resin to cure too slowly, resulting in longer drying times.

Impact of High Temperatures

In hotter conditions, cured resin may become less clear and more yellowed due to excessive heat exposure. To prevent this from happening:

  • Try working in a temperature-controlled environment or during cooler parts of the day.
  • Keep your materials out of direct sunlight when not in use.

Curing Times and Viscosity

Higher temperatures can significantly shorten the amount of time you have to work with epoxy resin before it starts to harden. This is known as the "pot life." Here's what you should know:

  • The higher the temperature, the more limited the pot life.
  • Plan your projects accordingly based on the expected pot life at your working temperature.

Recommended Humidity Levels

Humidity refers to the amount of moisture present in the air. Here's how humidity can affect epoxy resin:

  • In high-humidity environments, epoxy resin may take longer to cure and may not fully harden.
  • Epoxy resin may cure too quickly in low-humidity environments, resulting in a weaker finish.

Aim for humidity levels between 40% to 60% during the curing process for best results. Here are some tips for controlling humidity:

  • Use a dehumidifier in order to remove excess moisture from the air.
  • Turn on an air conditioner or fan to increase air circulation.
  • Avoid working in overly humid or dry conditions whenever possible.

Understanding these temperature and humidity considerations is essential for successfully working with epoxy resins in the summer.

2. Storage Recommendations

Proper storage is essential for ensuring the quality of epoxy resin, especially during the summer months. Exposure to direct sunlight can have damaging effects on resin properties, leading to issues such as discolouration and accelerated deformation. To preserve the quality of epoxy resins, consider the following storage recommendations:

Avoid Sunlight Exposure

Store epoxy resin in a cool, dark place away from direct sunlight. Ultraviolet (UV) rays can initiate chemical reactions in the resin, causing it to turn yellow and become breakable over time. Consider using opaque containers or tinted bottles to shield the resin from light exposure.

Temperature Control

Maintain a consistent storage temperature within the recommended range to prevent fluctuations that could compromise the resin's composition. Extreme heat can accelerate the curing process within the container, leading to a shortened shelf life and a decrease in quality.

Sealed Containers

Ensure that the containers used for storing epoxy resin are tightly sealed to minimise air exposure. When applied, oxygen can interact with the resin, potentially leading to surface imperfections or a sticky texture.

3. Additional Tips for Working with Epoxy Resin in Summer

Consider following these additional tips for better results while working with resin in warm weather:

Monitoring and Controlling Temperature

Using a digital thermometer is crucial to ensure that the surrounding temperature and the resin mixture are within the recommended range for successful curing. This tool helps in making real-time adjustments to the working conditions, thereby preventing potential issues arising from temperature fluctuations.

Maintaining Airflow

Proper ventilation is essential to eliminate excess heat generated during the curing process. Simple measures such as opening windows, using exhaust fans, or using portable air circulators can significantly contribute to regulating the workspace temperature, especially in hot weather.

Avoiding Sunlight Exposure

Direct sunlight can accelerate the curing process and may lead to undesirable outcomes such as uneven finish or premature curing. Working in shaded areas or during cooler times of the day minimises the impact of external heat on the resin application, ensuring better control over the curing process.

Using Slower Curing Hardener

Utilising a slower curing hardener provides extended working time, which is advantageous when executing complex or large-scale projects in high temperatures. Adjusting the mixing quantities based on the slower curing hardener's specifications ensures that the resin can be applied and manipulated effectively before it sets.

Preventing Risks

In warm weather, epoxy resin mixtures may result in a shortened pot life due to accelerated chemical reactions, leading to increased exothermic heat release and higher chances of draining out. To counter these risks, carefully planning the application process, working efficiently with smaller batches, and implementing cooling measures become necessary.

Conclusion

As you wrap up your summer epoxy resin projects, remember to apply these tips for the best results. Find a well-ventilated area with a stable temperature to ensure smooth curing. Break down large projects into smaller pours to manage heat build-up and prevent cracking. Opt for a slower-curing epoxy during hotter months to allow for better air release. Explore the use of products like UV stabilisers or heat-resistant pigments to enhance durability in outdoor applications.
