Abstract: A U.V. curable composition for application to a substrate surface to provide a static dissipative coating which comprises a conductive matrix constituent having a crown type ligand selected from the group consisting of podands, coronands and cryptands in a guest/host relationship with a conductive dopant moiety. Such ligands included those provided by functionalized podands and functionalized coronands. The formulation further includes a polymer matrix constituent formed of a base oligomer system and a crosslinking agent which is reactive with the base oligomer system to form a crosslinked resin matrix which incorporates the conductive matrix constituent. A low viscosity diluent functions as a solvating liquid for the crosslinking agent and the base oligomer system. The formulation further includes a photoinitiator of the free radical or cationic type to initiate polymerization of the composition upon the application of electromagnetic radiation in the ultraviolet range.

Abstract: A composition and method for the removal of ionic salt deposits from a surface using an organic solvent of low polarity and a complexing agent. The complexing agent is chosen from a group which includes podands, cryptands, and coronands. The method provides nearly complete removal of ionic salt deposits with a single washing of the surface with the low polar cleaning mixture.

Abstract: In one form of the invention, an electronic device having a conformally coated Faraday cage, comprising a non-conductive conformal layer (30) substantially coveting the electronic device (10, 12) and a conductive conformal layer (34) substantially coveting the non-conductive conformal layer.

Abstract: The invention provides for a process of using a static dissipative, polymeric composition to prevent electrostatic discharge. The static dissipative, polymeric composition is both humidity independent and water insoluble. The present invention also provides an article comprising a substrate to be protected from electrostatic discharge.

Abstract: A metal tube is substituted for the plastic tube commonly connected to the actuator of aerosol spray cans of contact cleaning fluid. The brass tube is electrically connected by a wire to the electronic component being sprayed. An alligator clip or banana plug at the end of the wire provides a convenient connection to the circuit board. In one embodiment, a resistor connects the brass tube to a metal button positioned on the actuator to contact the finger of a person depressing the actuator to operate the aerosol can, and the person is grounded. In another embodiment, the brass tube is grounded as well as connected to the circuit board, and the person operating the actuator is insulated from the brass tube. In either embodiment, the brass tube effectively dissipates any static electricity generated by the aerosol stream or spray to the selected ground.
