DESCRIPTION:

A solvent dye is a dye soluble in organic solvents. It is usually used as a solution in an organic solvent. Solvent dyes 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. They form a colloidal solution in solvents. They have poor (basic dyes) to good (metal complex based) light fastness. Solvent dyes are used for gold imitation (and other transparent metallic effects) of metalized polyester films. Also used in marking inks, inkjet inks, glass coloration, and so on. These dyes are used extensively in fuel, oil, lubricant, grease, wax, and plastics coloration applications. These highly-concentrated heat-stable colorants, available in liquid and powder form, are soluble in polar solvents and hydrocarbon-based oil and lubricants. Their high concentration allows the formulator to use minimal amounts of dye thereby causing no change to the product’s original physical characteristics. In addition, their stability to high heat makes them a good match for lubricants, engine oil, automatic transmission fluid, and grease. Some lubricants are water-based and would require our water-soluble dyes or possibly pigments. The fluorescent dyes are used for leak detection in engines and hydraulic systems, and oil/water path detection in oil-field applications. Petroleum applications include gasoline, diesel, jet-fuel, biodiesel, fuel additives, heating oil, and kerosene. APPLICATION: 1. Solvent dyes for Inks for rotogravure and rubber stereo printing; for coating copying paper and typewriter ribbons; for ball point pens, and in printing inks as shading and brightening agents and for double tone effects. 2. Solvent dyes for Petrol & Fuel Oils 3. Solvent dyes for Wax & Candles 4. Solvent dyes for Cosmetics 5. Solvent dyes for Wood Stain, Spirit & Varnishes. 6. Solvent dyes for Coloration of molding powders, construction material of cellulose acetate, celluloid, polystyrene, polymethacrylates, PVC, P/F, U/F. 7. Solvent dyes for Leather- spray finishing of dyed & undyed leather. 8. Solvent dyes for Aluminum foil printing, transparent lacquers, nitrocellulose, cellulose acetate, vinyl, alkyd, other synthetic resins or shellac.
