ABSTRACT:
Easily removable conformable coatings having a controlled thickness with a predetermined minimum value are obtained by the application of a composition comprising a mixture of a viscous carrier material and small particles of a second material by any known method. When both the carrier material and the particulate material mixed therewith are selected to have high dielectric constants, the mixture may be used to obtain coatings suitable for protection of circuit boards supporting high impedance electrical circuits. A mixture of a commercially available grease, e.g., Amoco RYKON (TM), with glass microspheres comprising up to 50% of the volume and preferably in the size range 3-5 mils, provides excellent dielectric conformal coatings for high impedance circuit boards. By contrast, by selecting both the viscous carrier material and the particulate matter mixed therein to have high conductivity, electrically conductive coatings for particularized users may likewise be obtained according to this invention.
