Our lab does not have a coating machine, so I am unable to process polycarb lenses when generating Safety glasses, is there a suitable sub-material that can be used???
Spectralite or another mid index lens?
Question on safety lens material?
Spectralite or another mid index lens?

My lab days were before Trivex, doesn't it need to be backside coated?Originally Posted by Jacqui
plastic at 3.0 is ansi Z87.1, only poly and trivex can achieve the Z87.2 impact resistance

Unfortunately the words only meant something to me.
No plastic needs to be coated in any way. Trivex will take a spin coating or even a dip-it style.

Ok, am I being dense, he/she doesn't have a coating machine, how could he use Trivex? Are there air dry hard coats?

YES, there are and they're wunnerfull !! OMS, BPI and others have them. Just dip, leave in solution for specified time and rinse, instant hard coat. Been around longer that spin coating. :D:D

k12311997, You really need to get back in the lab and catch up on the latest developements.

I won't say hard coat. Scratch resistant will be more appropriate. For what I know (But I may be wrong) this is a product who just make the lenses more slippery. But not really harder.
I use steel wool (0000) to test my hard coat and it don't scratch :D. I test this product once with steel wool and lthe lens looked like :shiner:.
But that was long ago and maybe the product is better now.
