Mr.Resin Black Line UV Resin is a premium epoxy based low viscosity formula. Although it is epoxy based it will still require the use of a uv lamp for curing. Our black line resin is nearly odorless, easy to use, cures quickly, and uses a professional grade UV inhibitor for enhanced long term yellow resistance. The low viscosity of this formula enhances its resistance to bubbles. Great for jewelry making, keychain making, rock painting, polymer clay coating, etc.
