When used as an additive at low dosage (0.5% - 5% w/w) in another UV-curable formulation, 1939 does not require special curing conditions. When a high content (25% to 90% w/w) of 1939 is desired, a suitable photoinitiators (such as Speedcure TPO-L) and reactive diluents (such as Sartomer SR351/TMPTA, SR238/HDDA and/or SR285/THFFA) may be needed. After diluting the mixture with butyl-acetate, ethyl-acetate or similar solvent, apply the mixture on the substrate using spray, roll, doctor blade, meter rod, etc. to obtain a coating of the desired thickness. After the solvent has evaporated, irradiate with LED lights (12W/sqcm @ 385/395/405 nm) for 3 seconds with the light source 4 mm from the mask (alternatively, if a MicroCure CTO-46 is used photo-initiator, irradiate with a medium pressure vapor mercury lamp (220-320 nm UV, if possible under inert nitrogen) to a pencil hardness of greater than #2 at 3 Joules per square centimeter for 60 seconds).
