BobP Posted December 30, 2020 Report Share Posted December 30, 2020 You got me. I also have a bottle of Chinese uv resin, about a year old. It’s still the same viscosity liquid as when new. When I used it as clearcoat last week, it took about 40 minutes in my fingernail uv curing box to properly harden. Not much longer than it took when fresh, but maybe slightly longer. I think the longer cure time may just be typical for Chinese resins. The Alumi-UV resin reportedly cures in a few minutes. It’s also much more expensive, so “player’s choice”.

JimP Posted January 2, 2021 Report Share Posted January 2, 2021 I have a bottle of Loon UV that is a couple of years old and still cures the same as always. Try a different light maybe. Quote Link to comment Share on other sites More sharing options...
Anglinarcher Posted January 13, 2021 Report Share Posted January 13, 2021 My guess is that the UV is separating. Try mixing the containers well, very well. I have some Alumilite Mike sent me when he first started to sell it and it is still good. So...... I also have some older Loon for fly tying and it is also great. But, I suspect the Alumilite and Loon use higher quality emulsifiers. Quote Link to comment Share on other sites More sharing options...
mark poulson Posted January 13, 2021 Report Share Posted January 13, 2021 When I had my UV curing slower, I replaced the bulbs on my nail light box, and that fixed it. Evidently they do wear out. 1 Quote Link to comment Share on other sites More sharing options...

Evidently they do wear out. That is true. UV lights have a life, just like the light bulb in your living room. Except, they don't always burn out, but change frequency. 1 Quote Link to comment Share on other sites More sharing options...
