Epoxy Resin vs UV Resin: Which Is Better for Your Business?
Understanding the Difference
Choosing between epoxy resin and UV resin is one of the most common questions from new craft business owners. Both have their place, but the right choice depends on your product line and production volume.
Epoxy Resin (AB Type)
Two-part resin that cures through a chemical reaction when Part A and Part B are mixed. Curing takes 12-24 hours at room temperature.
Pros: Crystal clear finish, strong and durable, ideal for large pieces (trays, tables, deep molds), cost-effective for bulk ($1.50-3.00/kg wholesale), no special equipment needed.
Cons: Long curing time, requires precise 1:1 or 2:1 mixing ratio, bubbles need heat gun/torch treatment, not suitable for quick-turnaround products.
Best for: Jewelry, coasters, home decor, large molds, deep pour projects.
UV Resin
Single-part resin that cures instantly under UV light (365-405nm wavelength). No mixing required.
Pros: Cures in 2-3 minutes under UV lamp, no mixing or measuring, perfect for small items and quick production, minimal bubbles, easy for beginners.
Cons: More expensive per unit ($0.35-0.60/pc wholesale), limited to thin layers (under 3mm), can yellow over time with sun exposure, requires UV lamp investment.
Best for: Small jewelry, quick repairs, layering thin coats, encapsulated flowers/glitter, high-volume small-item production.
