Step 1: What is epoxy resin?
Epoxy resin is a two-part system made by mixing resin and hardener.
Once Parts A and B are mixed in the correct ratio, a chemical reaction begins and the resin gradually cures.
Epoxy resin is commonly used for:
- Coasters
- Trays
- Clocks
- Nameplates
- Frames
- Jewellery
- Deep casting
- Flower preservation
- Varmala preservation
Fusion Resin offers Vitro 2:1 for coating and shallow projects.
For deeper casting, Flex 3:1 is designed for deep-pour applications.
Step 2: What is UV resin?
UV resin is a resin that cures when exposed to UV light.
This makes it convenient for small projects where you want a quick cure.
It's commonly used for:
- Small jewellery
- Tiny charms
- Small embellishments
- Miniature decorative pieces
Step 3: Which one is better for beginners?
It depends on what you want to make.
If you're making small jewellery or tiny decorations, UV resin can be convenient.
If you want to make coasters, trays, clocks, nameplates or larger resin artwork, epoxy resin is generally more suitable.
Step 4: Which is better for deep casting?
For deep casting, use a resin specifically formulated for deeper pours.
Fusion Flex 3:1 – 1.2kg is designed for casting applications such as:
- Flower preservation
- Varmala blocks
- Deep moulds
- Paperweights
- Large casting projects
Do not choose a coating resin simply because it looks clear. Pour depth is an important part of resin selection.
Step 5: Which one should you choose?
Choose epoxy resin if you want to make:
- Coasters
- Trays
- Wall clocks
- Nameplates
- Frames
- Jewellery
- Flower preservation
- Varmala preservation
- Deep blocks
Choose UV resin if you mainly want:
- Small charms
- Tiny jewellery
- Small decorative pieces
- Fast-curing miniature projects
