FluoroPel hydrophobic and oleophobic conformal coatings are perfluoroalkyl copolymers. Applications for FluoroPel include coating membranes, plastic laboratory devices, microfluidic devices, printed circuit boards, ball-grit arrays, MR heads, micro-motors, MEMS, and hard disk drive components. Fabrics, mesh, filters and membranes coated with FluoroPel retain air permeability, Rayl values and acoustic penetrance. Oleophobicity grade of up to 8 can also be achieved. FluoroPel is provided as a clear, low viscosity, low surface tension solution usually at 0.2% to 10% polymer in either fluoro or organic solvents. FluoroPel has also been formulated to prevent corrosion, sweat damage, tin whiskers and dendrites.
