Description
Concentrated solutions of meal complex dyestuffs.
This range has been carefully selected in order to obtain very brilliant colors with good heat and light fastness properties. DS are water and organic solvent mixable and can be used at any stage in the finish operations from spray dyeing to final lacquering; they are compatible with anionic or nonionic products normally used, as well as with emulsion and solvent lacquers. They cannot be used in two components PU lacquers.
The increasing popularity of the natural or unfinished look has brought about a great many changes in finishing technology. One of the most important developments has been the preparation of low VOC dyes that provide lively and more brilliant colors. In addition, these new dyes possess superior light fastness and fade resistance to those previously used.
This series of liquid dyes is far more environmentally suited for use in today’s leather finishing. These high flash, low VOC dyes may be cut with water or solvents for use in stain coats. They also have better compatibility with aqueous resins and auxiliaries than other dye series. However, they may still be used in lacquer emulsions and solvent borne lacquers.
With current regulations calling for reduced volatile organic compounds, and leather finishers using more waterborne systems, Leather Technologies new low VOC DS series dyes are sure to be an asset to the leather industries and the environment.
The base coat finishes, resin finishes or lacquering quantities to be used will vary according to the required depth of shade, we recommend 10-50 gr./liter. For spray dyeing DS can be used with water and organic solvents such as ethyl glycol (cello solve); ethyl alcohol; isopropyl alcohol or ethyl glycol substitute.
