MicroCure UV72 is a hydrophobic, oleophobic fluoro-acrylate UV-curable oligomer with excellent resistance to solvents, water, water-vapor, oils, stains and abrasion. Substrates for UV72 include PCBs, plastic, metal, glass and ceramic. UV72 can be applied by dip, spray, jet, roll, draw or brushing. When smooth and well-cured, contact angles to mineral oil of greater than 65° and roll-off angles of less than 3° can be achieved.
