ONGHSD Epoxy UV Resin Clear Hard, UV Jewelry Resin Glue Sunlight Ultraviolet Curing Resin Crystal Liquid for DIY/Kids Craft Jewelry Making Supplies Mold Not Included (25g/0.88oz)

Quality of product.

I mix this with some of my builder gel, and when I say my nails are beyond hard as a rock!!!! I use a very good builder gel, but this helps to make it easier to install, as the gel is crazy thick and sticky. Couple of coats, cure, top coat - my nails have stayed on for ever three weeks and so have my clients.

This is a good resin if you are using it to adhere two things. No bubbles and medium fluid consistency. However I would not use it alone for making resin objects, domes, etc. The top does not completely harden to glass hard. It is a bit sticky and soft no matter how long I keep it under the LED light.

Works as it should

So I mostly like this UV resin and this is the only one I have used so far so I don't have anything to compare it too. It is stinky so wearing a respirator mask is wise. Also pay attention to the wave length it says it needs not just that it needs UV light. If you have lots of sunshine then that is great but if not not all UV lights are the same and that can make a world of difference in the ability to cure the UV resin. Plus the whole adding anything to color it is problematic. I've had lots of pieces not cure even though the lamp I use is within the right wave length and I do short bursts and cure from both sides before I demold a piece and then I cure more. I've even had issues with clear pieces not wanting to cure. Its a frustrating skill to learn for sure.
