The problem of oxygen resistance of curing materials in liquid form, oxygen in the air will diffuse among them.

And then the free radicals will combine to form peroxide free radicals.
They will prevent the progress of curing.
It is not good to once it reflects uv curing effect.
Then the speed is not fast and so on.

The simplest way to solve the problem of oxygen resistance polymerization is to improve the radiation illumination.
So as to improve the initiation efficiency of the cured surface.
And increase the number of free radicals produced, shorten the curing time.
So as to reduce the time of free radicals contact with oxygen.
And reduce the depth of oxygen diffusion.
However, the disadvantage of this method is the existence of excessive radiation.
It may lead to heat deformation, aging and other problems of the paint film.
For industrial applications or demanding users, it requirs the qualitative and quantitative analysis.https://www.tank007.com/product-category/uv-flashlight/
