What is UV resin?

There’s a huge range of different resins on the market. Epoxy Resin, Eco Resin, UV Resin. But what exactly is UV resin and how can you use it?

UV resin, also known as ultraviolet resin, is a type of liquid resin that cures (hardens) when exposed to ultraviolet (UV) light. It’s often used in various crafting and DIY projects, particularly in jewellery making, model building, and small-scale prototyping.

UV resin typically comes in a one part (no mixing required) liquid form and can be transparent or coloured.

When you apply UV resin to an object or surface, it remains in a liquid state until it’s exposed to UV light. Once exposed to UV light, usually from a UV lamp or sunlight, the resin undergoes a chemical reaction called polymerization, where its molecules link together to form a solid, hardened structure.

What are the advantages of UV resin?

One of the advantages of this type of resin is its quick curing time. Compared to other types of resin, such as epoxy resin, UV resin cures much faster, often within minutes, under the right conditions. This rapid curing time makes it popular for projects that require speedy results.

Is UV resin safe?

Like all resins, it’s important to follow safety precautions when working with UV resin. Every brand will come with its own set of safety instructions which must be followed to ensure your safety. We recommend that you always wear protective gloves and ensure you have proper ventilation in your workspace. You should also use UV light sources responsibly to avoid overexposure and over heating of resin or electrical equipment.

UV resin can stick to most surfaces so we suggest you always cover your work space and clean any spillages as soon as possible.

What do you need to craft with UV resin?

The main things you’ll need are:

  • Moulds / pendants
  • UV Resin
  • UV Lamp / torch
  • Resin tape (if not using a mould)
  • Protective gloves
  • Colour / texture (like glitter or flowers)

We recommend the JDiction UV Resin Starter Kit which contains absolutely everything you could possibly need (and more). Its often on offer on Amazon too making it really good value for money.

Is UV or epoxy resin better?

We love UV resin because of its really quick curing time and the fact there’s no messy mixing. This makes it great if you don’t have a permanent crafting station and need to tidy away when you finish. You also don’t need to worry about leaving projects curing over night.

We think UV resin is perfect for making smaller pieces like jewellery and due to its low cost, you can make a relatively decent profit on items quite quickly.

If you’re looking to make bigger projects or add more colour and texture, then epoxy resin is absolutely still worth the effort.
