How To Make Resin Tray


Choosing the Right Resin

When it comes to making a resin tray, choosing the right resin is essential. Resin is a viscous substance that hardens when mixed with a curing agent and offers a beautiful, glossy finish. There are two main types of resins commonly used for tray-making: epoxy resin and polyester resin.

Epoxy Resin: Epoxy resin is a popular choice for making resin trays due to its exceptional clarity and good UV resistance. It is also known for its strong adhesive properties, making it suitable for bonding different materials together. Epoxy resin is self-leveling, which means it spreads evenly and minimizes the risk of uneven surfaces. Additionally, epoxy resin has a longer working time, allowing for more flexibility during the pouring and manipulation process.

Polyester Resin: Polyester resin is another option for making resin trays. It has a lower cost compared to epoxy resin and has good heat resistance. Polyester resin tends to cure faster than epoxy resin, which may be advantageous if you prefer a quicker project. However, it is important to note that polyester resin is not as clear as epoxy resin and may develop a slight yellow tint over time.

When choosing the right resin for your tray, consider the specific requirements of your project. If you prioritize clarity and UV resistance, epoxy resin is the ideal choice. On the other hand, if cost efficiency and faster curing time are more important, polyester resin may be the better option. Take into account the desired outcome and durability of your resin tray to make an informed decision.
