Does UV Light Help Cure Resin?

Does UV light help cure resin? UV light can be used to harden particular glues, resins and inks by causing a photochemical reaction inside those substances. This process of hardening is called 'curing'. mixing in another substance that triggers the hardening process – Araldite is a well-known glue that uses this process.

Does epoxy resin cure without UV light?

Short answer: UV light won't affect the cure of non-UV resin. Strong UV may even discolor or degrade some types of non-UV resin. UV-curing resin works on a different mechanism. A one-part resin is stable until UV of a particular wavelength breaks down a component in the resin and causes it to cure.

Does resin harden faster with UV light?

Look for a UV light source that's strong enough to cure the type of resin you're using. 4 watts is typically enough, but check the directions on your resin product for any specific UV light strength or wavelength requirements. In most cases, UV lamps are stronger and will cure your piece faster than UV flashlights.

Will UV resin cure on its own?

The resin can be used for a very long time, as it does not cure without the aid of a UV lamp. Curing by UV light is completed within a very short time.

Can you cure epoxy resin with hair dryer?

A great way to quickly dry your epoxy resin is to use heat. In that case, you can use a warm room to do your craftwork. However, if you want the resin to dry extra fast, you can apply heat with a heat lamp, heat gun, or blow dryer. This option is quite effective for drying resin well.

How do I speed up resin curing time?

  • It is actually possible to make epoxy resin dry faster, just by using heat.
  • Increase the temperature to 75-85ºF / 24-30ºC in the room where your piece is curing.
  • The resin reaches 95% of its full cure within 24 hours, and 100% of its cure within 72 hours.

  • Why is my epoxy not hardening?

    If your epoxy resin hasn't cured properly, this means that the chemical reaction between the resin and hardener was not able to take place. Sticky resin is typically caused by inaccurate measuring or under mixing. Try moving your piece to a warmer spot: if it doesn't dry, re-pour with a fresh coat of resin.


    Will a black light cure epoxy resin?

    The "blacklights" you are talking about are a useless wavelength for what is needed to cure the resin. Yes, they will EVENTUALLY cure the repair but so will a fluorescent light in the right amount of time.


    What's the difference between UV resin and epoxy resin?

    UV resin requires no mixing because it is available as a single liquid, which can be used right away without a hardener. It is a bit more expensive than epoxy resin and is usually packaged in smaller volume bottles. UV resin is best to use on flat projects that can be cast using only thin layers.
