Understanding the Difference

Epoxy resin and UV resin are both popular in the crafting world, but they serve different purposes. Understanding their differences helps you choose the right material and purchase the right inventory.

Epoxy Resin

  • Curing: Chemical reaction between resin and hardener. Takes 12–24 hours.
  • Strength: Very durable, heat resistant, can be sanded and polished
  • Thickness: Can pour thick layers (up to 1 inch at a time)
  • Best for: River tables, coasters, large art pieces, jewelry with deep molds
  • Shelf life: 6–12 months once opened
  • Price: $20–$40 per gallon (resin + hardener)

UV Resin

  • Curing: UV light activation. Cures in 2–5 minutes under a UV lamp or 10–15 minutes in sunlight.
  • Strength: Hard but more brittle than epoxy. Cannot be sanded aggressively.
  • Thickness: Maximum 3–5mm per layer (thicker layers may remain sticky inside)
  • Best for: Small jewelry, charms, stickers, bookmarks, hair clips, phone cases
  • Shelf life: 12–18 months (unopened at room temperature)
  • Price: $15–$30 per 500ml bottle

Which sells better? UV resin kits outsell epoxy kits 3:1 on Amazon and Etsy — faster crafting time appeals to hobbyists. However, epoxy resin is preferred by professional crafters and bulk buyers.

Stocking Advice for B2B Buyers

Carry both product lines to maximize market coverage:

  • UV resin kits: Target hobbyists, gift shops, craft stores
  • Epoxy resin (clear, non-yellowing): Target serious artists, furniture makers, industrial crafters
  • Combination kits: Offer "starter bundles" with small epoxy + UV resin bottles, 2 molds, and pigments
