FluorAcryl 1939 is a bifunctional perfluoropolyether (PFPE) urethane acrylate. FluorAcryl is a surface modifier that improves gloss. It is compatible and miscible with low molecular weight reactive UV-curable diluents and acrylic monomers. Some of the properties of FluorAcryl 1939 include good release agent, good water and oil repellency and good chemical resistance. As a surface modifier this also offers good hardness, substrate-wetting and flow-properties. Recommended dosage is between 0.5–5% w/w. During application and UV light curing, FluorAcryl blooms quickly and effectively on the surface of the coating, imparting low surface energy and non-stick E2C properties. FluorAcryl is made for UV curable coatings use.

Chemical Resistance, Improved Hardness, Improved Substrate Wetting, Oil Resistance, Water Resistance. 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).
