Epoxy resin is a strong and durable material that is used in a variety of applications, from jewelry making to boat building. It is usually cured with ultraviolet (UV) light, but can it be cured without UV light?The answer is yes, but it depends on the type of resin you are using. Some resins are designed to be cured with UV light, while others can be cured without it. Strong UV rays can even discolor or degrade some types of non-UV resin.
The UV curing resin works with a different mechanism. A monocomponent resin is stable until UV rays of a certain wavelength break down a component of the resin and cause it to cure. No, UV glue cannot be cured without UV light. UV adhesives and resins require UV radiation to harden. Leaving the glue exposed to sunlight may be enough if you don't have a flashlight or lamp, which is why some people think the glue will eventually harden.
However, UV glue cures by exposure to light and not by temperature or other environmental conditions. To prevent damage to objects, you should always use a UV lamp or flashlight for faster and more uniform curing. Another way to cure UV resin without the use of a UV light is to leave it at room temperature for 72 hours. You can use an oven or heat lamp to cure clear silicone rubber molds with this method.
