How to Choose the Right Resin for Your Projects
Each resin possesses unique properties, so different factors need to be carefully considered in order to be able to choose the one that best suits your project and your wishes. Below are 6 factors you need to consider carefully before deciding to choose resin.
Purpose of the Artwork
Clearly defining the purpose of your artwork is the first and most important thing in choosing the type of resin. Do you want casting, coating, or bonding? This will help you narrow down your resin options because different resins will have superior properties in different applications. For example, if you want to preserve your favorite flowers in resin, then transparent casting resin would be a perfect choice.
Depending on how long the project takes, you may need a resin that works quickly or a resin that allows you more time to manipulate and adjust. If this is your first time working with resin, a resin with a long set time is more suitable as it offers more flexibility in the fabrication process. However, faster-curing resins are often more expensive and may have less desirable properties, such as lower strength and durability. It is important to weigh the benefits and drawbacks of speeding up the curing process before making a decision. Normally, to completely cure: UV resin takes 5-10 minutes, epoxy resin takes 72 hours, silicone resin takes 24 hours, polyester takes 12 hours…
Durability is also an important aspect in making your resin selection decision. Different resins have different hardness, impact resistance, abrasion, and service life. Consider the environment in which your artwork will be displayed or used, and choose a plastic that can withstand those conditions. If you are making a piece of furniture that will be used heavily, you will need to choose a resin that is resistant to scratches, dents, and chips. Epoxy resin is a good choice for durable furniture projects.
The surface finish of your artwork is another important factor to consider as it directly affects the aesthetics of the artwork. Resins can create different surface finishes, from glossy and reflective to matte or satin. Determine the desired finish with the properties of the resin to ensure that the aesthetics and beauty of the artwork meets your expectations.
Safety and Health Considerations
Some types of plastic will have less odor and are safe to use, such as Polyurethane (PU), Polyethylene (PE) and Polypropylene (PP). On the contrary, some types have a very strong odor and emit toxic and harmful fumes. for human health. Make sure you choose a plastic that is safe for your health. If the plastic that meets all your other expectations is harmful to your health, you need to wear protective equipment such as masks, gloves and glasses. You also need to make sure to do it in a spacious, well-ventilated place
Budget and Cost Considerations
Different types of plastic come in different price ranges, and it's important to strike a balance between quality and affordability. If you are on a tight budget, you may want to choose a less expensive resin, such as polyester resin. However, keep in mind that polyester resin is not as durable as some other types of resin.
