FluorAcryl is a family of water, oil and chemicals repellent UV-curable coatings. These are transparent, anti-reflective and very tough. FluorAcryl 7298 is particularly good as an additive in other UV-curable inks and coatings to enhance water and oil repellency. A major application for FluorAcryl is as a negative photoresist that repels water, oil, biofluids, chemicals, protein, DNA, etc.

FluorAcryl 3298 FluorAcryl 3298

FluorAcryl 3298 is a hydrophobic, oleophobic fluoro-acrylate UV-curable oligomer with excellent resistance to solvents, oils, stains and abrasion. Substrates for 3298 include PCBs, plastic, metal, glass and ceramic. 3298 can be applied by dip, spray, jet, roll, draw or screen print methods after dilution. 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. 3298 is stain resistance. Magic marker stains beads up and is removed by an alcohol wipe. 3298 is also ice repellent.

FluorAcryl 7298 FluorAcryl 7298

FluorAcryl 7298 is a perfluoropolyether (PFPE) acrylate used as an additive in other UV curable coatings to reduce surface tension and improve water, oil and stain resistance. This fluorinated acrylate is transparent, hydrophobic and oleophobic with exceptional hardness, toughness, heat, and chemical resistance. Films and coatings with 7298 may be expected to provide anti-fouling and easy cleaning from fingerprints and other contaminants. FluorAcryl 7298 is compatible with many monomers, such as TMPTA. With or without pigments and other particulates, 7298 rapidly UV cures in the presence or absence of oxygen.

MicroCure UV72 MicroCure UV72

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.
