MicroCure UV72 is a hydrophobic, oleophobic fluoro-acrylate UV-curable oligomer with excellent resistance to solvents, 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. MicroCure UV72 is stain resistance. Magic marker stains beads up and is removed by an alcohol wipe.
