Solvent Containing Coating composition contains hydroxyl-containing saturated copolyester, a phenol-formaldehyde resin, a benzoguanamine-formaldehyde resin and/or a blocked polyisocyanate. Solvent containing coatings are used for osmosis prevention. The solvent containing coatings are classified as hazardous according to the ASCC approved criteria for classifying hazardous substances.
Solvent dye is a dye which is soluble in an organic solvent and is mostly introduced in the form of a solution in an organic solvent. These are used to color organic solvents, hydrocarbon fuels, waxes, lubricants, plastics, and other hydrocarbon-based nonpolar materials. Fuel dyes are one use of solvent dyes. Their molecules are typically nonpolar or little polar, and they do not undergo ionization. They are insoluble in water. It is usually used as a solution in an organic solvent.
Solvent extraction columns consist of a distributor for receiving feed liquid introduced into the column through an inlet port. The distributor comprises an endless open channel having a plurality of spaced apart apertures. The distributor is positioned adjacent the inlet port and feed liquid from the inlet port enters the channel and is distributed through the apertures over the column.
