*Keep in mind, the deeper the pour, the more intense color you will achieve. The UV Light must be able to penetrate through the piece or it will not cure so some colors may be more transparent than others, but layering and adding glitter will do the trick.
Wattage and Time to Cure
We recommend using at least 24-36W UV lamps. Higher wattage will work, but could cause yellowing of the resin and more fumes, which is why our resin has a minimal cure time (60-120 seconds front and back). All brands of UV resin can let off fumes and have an odor. Some are stronger than others - Resin Rockers is much less.

My resin still feels sticky, even after the recommended cure time. What do I do?
If your resin still feels sticky even with more than the maximum cure time, make sure you are letting it rest for an hour or two after the initial cure. The resin will still need time to harden up to its full rock-hard, durable finish. Also take into consideration your work environment. If it is humid or cold, that will affect the cure also. Give it a little extra time, maybe even sit it in the window sill for a few hours. Also consider curing in thin layers. This is still a transparent resin, but due to the tint, it will take longer for the light to penetrate all the way through. Also be sure you are curing on both sides if you are using a mold. Be sure your mold is transparent and still in good condition. If your mold has turned white from excessive use, consider a new one because the UV light must be able to penetrate the piece.
What is the heat resistance for Resin Rockers UV Resin?
Resin Rockers UV Resin is heat resistant up to 150 degrees F but you should still protect your pieces in that kind of temperature as much as you can. Especially if you are using elements in the resin that may not be as heat resistant like vinyl, pigment, etc. Also remember metal is a conductor so if you are making keychains, they could get extremely warm where the metal is.
How do I know my piece is cured?
It will not be sticky to the touch. If doing a piece in layers it should be fine but anything over 1mm will need to be in a silicone mold and cured right side up, then upside down to make sure the UV can get everywhere it needs to. Our UV resin cures within 1 minute depending on the wattage and the type of lamp. You need an LED UV lamp of 24-36W.
Does it matter what kind of glitter I use?
YES! Always check the label and make sure it is manufactured with PET – a high heat and solvent resistant material.
Can I mix epoxy and UV?
Not in liquid form. You can however dome your pieces made with epoxy once they are cured or layer pieces by lightly sanding with 1200 grit sand paper, wiping with rubbing alcohol, then coating with UV resin and curing it.
Why is my piece textured after I cure it when I use glitter?
All UV resin can cause a little shrinkage during the cure so the glitter texture may be more prominent. Dome your pieces with more resin after you cure and you will get that nice shiny finish!
What is the difference between a UV lamp and a LED UV lamp?
An LED UV lamp will do a better job and cure it quicker. A plain UV lamp will take a lot longer, but it is much lower heat so it will aid in eliminating pinholes. You must be particular with your UV lamp if you decide to go without the LED. 36W is recommended. It will also take a little longer to cure without the LED.
Is UV Resin safe to use?
Absolutely - if you use the proper protective equipment! It is non-toxic and safe to use inside as long as you are in a well-ventilated area. All brands of UV resin can emit fumes. If you are using a higher wattage UV LED lamp, you will get a lot more fumes, which is why we recommend using the lower wattage (24-36W). Be sure to wear nitrile gloves and protect your skin in case those with sensitive skin have an allergic reaction or lung irritation. Every person is different so we always advise to be cautious no matter what kind of chemical you are working with. Safety is always #1! We recommend usage for ages 15+.
Why does my UV resin smell?
All brands of UV resin have an odor. There is not a way around it due to the chemical make up. However, Resin Rockers UV Resin has a less pungent smell than most and has a unique formula meant to emit the least amount of fumes possible with a very low wattage.
