Using epoxy and other resins feels different. Epoxy resin comes in two parts. You mix resin and hardener before you use it. This gives you time to work, but you must measure well. Epoxy is thicker than other resins. It stays where you put it. This helps when you coat or fill a mold.
Polyester resin uses a catalyst and sets faster. It is easier for big projects, but you need fresh air. Polyurethane resin is bendy and pours well, but mixing can be tricky. UV resin is the easiest. You use it from the bottle and cure it with a UV lamp. This makes it good for quick crafts and jewelry.
Tip: UV resin is the simplest to use. Epoxy resin is better for big, strong projects.
Curing time is important when picking a resin. Epoxy resin takes longer to cure. Some types set in 15 minutes, but most need 8 to 30 hours to demold. Full curing can take up to 7 days. This slow time lets you fix mistakes and remove bubbles.
Polyester resin cures faster, often in a few hours. Polyurethane resin also sets quickly. UV resin cures in just minutes under a UV lamp. If you want to finish fast, UV resin is the best choice.
Resin Type | Pot-life | Demold Time | Full Cure Time |
|---|---|---|---|
Epoxy Resin | 15-100+ min | 8-30 hrs | 5-7 days |
Polyester | Short | 1-2 hrs | 1-2 days |
Polyurethane | Short | 1-2 hrs | 1-2 days |
UV Resin | N/A | Minutes | Minutes |
If you need more time to work or fix bubbles, epoxy resin is best.
Cost is a big thing to think about with resins. Epoxy resin costs more than polyester or polyurethane resin. For example, a 1.5 kg mix of epoxy resin can cost about £26.04.
