Abstract: There is disclosed a method for treatment of an oil slick resulting from an oil spill on a body of water. The oil slick is treated with a mixture of a granular elastomeric gum comprising a block copolymer of ethylene/butylene and styrene and an oleochemical synthetic wax, the latter being used in amounts of from 1 to 33 weight percent of the mixture. The adsorbent mixture has a low density, typically from 14 to about 15 pounds per cubic foot and will absorb oil and form a dry solid which has a non-tacky and non-oily surface. The adsorbent mixture is broadcast on the surface of an oil slick in proportions from about 0.2 to about 1 part per weight part of oil. The wave action on the body of water is generally sufficiently turbulent to admix the absorbent with the oil of the oil slick, resulting in the formation of floating solids which are dry to the touch and which have a non-oily, non-tacky surface. These solids can be readily recovered from the water or from a shoreline after they have washed ashore.

Abstract: There is disclosed a composition useful as a solder mask coating for use in the manufacture of printed circuit boards and the like which comprises a mixture of an alkyd resin and an alkylated amino resin, a minor quantity of a hydrocarbon resin, an inorganic filler derived from sedimentary shale of a particular origin, and sufficient organic solvent to provide a working viscosity suitable for silk-screening applications. The invention comprises also the use of a preferred and particular inorganic filler known as Panamint Earth.
