Solvent dyes are suitable for use in transparent lacquers flexographic and gravure printing inks and wood stains and for colouring anodized aluminum and plastics such as cellulose nitrate, cellulose acetate and polyester resins.

Petromate Liquid Dyes are used in coloration of petroleum products, primarily Gasoline, but also in Aircraft and Diesel Fuels, Lubricants, Hydraulics Fluids, High Boiling Distillates, Grease, Home heating Oils, Gasoline Additives and Kerosene. Usages From identifying sources and tax enforcement to detection of leak the uses of Petromate Liquid Dyes are numerous. Thus these products also help in identification of. Fuel Adulteration - Corporate Identity - Tax Evasion - Errors in mixing/ Blending. Petromate Liquid dyes also help to create differentiation in various Petroleum products such as e Leaded & Unleaded - High & Low Octane Gasoline - High & Low Sulphur Diesel - Aviation Fuels Attributes: Petromate Liquid Dyes are virtually chemically identical to the equivalent liquid dyes of other manufacturers presently being used in petroleum industry. Therefore Petromate Liquid Dyes can immediatly substitute those liquid dyes which are currently being used in petroleum industry, without any disruption of operations. Petromate Liquid Dyes are true liquid dye solution and thus offer advantage of having near zero insolubles, a distict advantage over powder dyes based liquid solutions. Petromate Liquid Dyes are available in full range of colours, encompassing all applications in petroleum products while having little or no impact on the properties and behavior. Petromate Liquid Dyes are dust free, highly soluable and readily handled. They are not extracted by water and remain colour fast under normal conditions. Consistant quality of these dyes make them the most reliable colouring product in petroleum industry.

Reactobond Reactive colors are five groups of reactive dyes manufactured by Meghmani Dyes and Intermediates Ltd for all cellulosic fibres, silk and viscose rayon. Reactive colors form a chemical linkage with the cellulosic fibres in the presence of alkalies, and therefore are characterized by their excellent fastness. Reactive colors are easy to use and applicable extensively in various fields such as exhaust dyeing, continuous dyeing and printing etc. Bi-Fuctional Dyes are reactive dyes containing monochlorotriazinyl and vinylsulfone group as a reactive radical and useful for dyeing of cellulosic fibres. There colors are suitable for exhaust dyeing (600C, 1400F), continuous dyeing and printing. Vinylsulfone Dyes are reactive dyes containing vinylsulfone groups as a reactive radical. REACTOBOND colors are suitable for exhaust dyeing (60'C, 1400F) continuous dyeing and printing. H-E Dyes are reactive dyes containing monochlorotriazinyl group as a reactive radical and high fixation on dyeing fabric blends on polyester / cotton. These colors are suitable for exhaust dyeing (801C, 1761F) of medium/heavy colors as high color yield. H-Dyes are reactive dyes containing monochloratriazinyl group as a reactive radical. Those are useful the Printing of cellulosic fibres and viscose rayon. REACTOBOND H-type colors are applied to steaming at 100-105'C (212-22loF) Dichloro Triazine Type Dyestuffs are reactive dyes containing dichloro triazinyl as reactive group. These colors are suitable for exhaust dyeing and also can be applied to cellulosic Fibre at room temp 35"C. Reactive colors are five groups of reactive dyes manufactured by Meghmani Dyes and Intermediates Ltd for all cellulosic fibres, silk and viscose rayon. Reactive colors form a chemical linkage with the cellulosic fibres in the presence of alkalies, and therefore are characterized by their excellent fastness. reactive colors are easy to use and applicable extensively in various fields such as exhaust dyeing, continuous dyeing and printing etc.  

These are Monosulphonated 1:2 Metal Complex Dyes characterized by Excellent Fastness to light. Suitable for the production of medium & heavy shades for automotive end-uses where high fastness is of prime importance. Excellent Compatibility Good wet fastness Wide shade gamut Good level dyeing properties On Polyamide, optimum coverage of barre when dyes are applied at elevated temperatures (105 - 120 Deg. C.) Good partition on Wool / Nylon blends. Suitable for low temperature dyeing Suitable for dyeing of all fiber blends with wool. Selected dyes suitable for resist and displacement printing of carpets

Megavat range of vat dyes are derived from anthraquinone. they are applied on cellulosic fibres to achieve overall high fastness. these products are marketed in the following physical forms. High conc. Powder Micro disperse They are insoluble in water. however, when they are applied on cellulosic fibre they are converted into soluble "leuco" form by addition of sodium hydrosulphite in the presence of sodium hydroxide. here, sodium hydrosulphite is acting as reducing agent. insoluble form of dyestuff is regenerated by oxidation at the end of dyeing process.

Optical Brightening Agents (OBA) or Fluorescent Whitening Agents (FWA) is added to many substrates to reduce yellowing, improve whiteness and enhance the brightness of the product. Optical whiteners function by absorbing ultraviolet radiation and re-emitting blue light. The emitted blue light will reduce the yellow color of the substrate and impart a pleasing whiter-than-white appearance. Optical brighteners give more intensity to some colors as well.
