UV resin is used in small DIY projects and can also be used to make jewelry. But is UV resin biodegradable and is it environmentally sustainable? We find out in this article.
What is UV Resin?
UV epoxy resin is a type of synthetic resin. UV-curing resins are materials that are polymerized and cured in a short amount of time by using the energy radiated from ultraviolet irradiation devices. Because of these properties, UV resin is commonly used as an industrial material for sealing, bonding, and coating surfaces.
UV resin doesn’t require mixing because it comes as a single liquid, which can be used immediately and without a hardener. It is generally more expensive than epoxy resin and is often packaged in smaller bottles.
UV resin cures (hardens) within a few minutes. The fastest way for UV resin to cure is under a UV lamp, but even natural light from the sun will assist in curing it. UV resin is best used on small DIY projects that can be cast using thin layers.
Is UV Resin Biodegradable?
Some types of UV resin are biodegradable.
Plant based eco UV resin is becoming increasingly common and is made from soy bean oil. Plant based UV resin will biodegrade naturally over time if left outside. You can speed up this process by using a composter.
Typical UV resins are made from free radical curing acrylic compounds (acrylates). These resins contain several synthetic additives and will not biodegrade naturally.
Polyester UV resin and epoxy UV resin also contain plastics and additives which will prevent them from biodegrading.
Is UV Resin Eco Friendly?
Most UV resin is not environmentally friendly.
UV resin is toxic and should be handled carefully. It contains organic volatile compounds (VOCs) and Bisphenol A (BPA).
UV resin should never be disposed of in liquid form. If poured down a drain or into soil it will harm natural wildlife.
It should be poured into a suitable container and allowed to cure before being thrown away in the garbage.
Plant based UV eco resin is non-toxic and is much more sustainable and eco-friendlier. It should still be handled and disposed of properly.
UV Resins are a very useful material but are very toxic. They are not sustainable, biodegradable or recyclable and should be handled with care.
The only exception to this is plant-based resins which are sustainable and much safer.
