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.

A solvent-free coating composition is useful for increasing the corrosion resistance of a surface is provided. The composition comprises a solvent-free coating material and an anti-corrosive agent comprised of a calcined mixture consisting essentially of magnesium oxide and zinc oxide with or without calcium oxide. The composition may also include a defined compound which can improve the corrosion resistance and fillers.

Solvent Recovery System is designed to process up to 125,000 SCFM of solvent laden air exhausted from the solvent drying zones of various coating lines. It is designed to operate in a semi-continuous mode to recover isopropyl alcohol. A solvent recovery system comprises the use of a heating component & a condensation component to distill the liquid and separate the solvent from water. Solvent recovery system distills & condenses solvents, thinners and cleaners.

Solvent recovery system is designed to operate in a semi-continuous mode to recover isopropyl alcohol (IPA), near it's azeotropic concentration, from an aqueous process stream generated in the production of a pharmaceutical. This system is subsequently operated in a continuous mode to dry the IPA, using azeotropic distillation.
