how long does it take for uv

[bigblue2]

I recently am trying out uv cured resin for clear coating it is taking a long time to cure under a 10 watt uv  lamp anyone  know why it is taking   so long I have heard it is suppose to take a matter of minutes but it is taking hours what am I doing wrong?

First, check to see that your uv lamp is the right one for your resin.

Then, use more than one light.  More light, closer to the bait will speed up curing.

Yeah, uv polyester resins require specific uv wavelengths to cure.  Maybe your light isn’t the right range.  As an alternative, you can put them outside for 10-15 mins and sunlight will do the trick, even on a cloudy day.

I got a 60watt uv flood lamp really speeds up curing time only 3 hours compared to 10 hours really happy about that!

I would get a different UV cure and verify the suggested wavelength.  I use Alumilite's UV and a fingernail UV curing light and it cures in 3 to 5 minutes.  I use to use Solerez and got the same results.

If you are having issues with hours, then the stuff you have is either separated (mix it), bad, or your lights suck.

I use Loon fly UV fly and knot cement with a small 9 LED hand held flashlight and it cures in seconds.

Something seems a little, OK A LOT, weird about your problem.
