We have synthesized a polymeric coating with pyrene units. It is showing fluorescence in UV region and not showing in visible region.
UV region based fluorescent coatings could be used as inks in anti-counterfiet applications.
Hi, I have a commercial epoxide material. It contains 10 mol% diol impurity in it. If anybody has information about the separation of the diol impurity from epoxide material, please share with me.
