The dyes listed here are water soluble anionic dyes selected from the acid, direct and reactive dye classes. They have good solubility in water and moderate solubility in glycols and alcohols. The suggested pH range for dyes listed herein is 5-9. We offer other specialty dyes for high PH and low pH applications.
Tracer dyes are commonly used for tracing water leaks, irrigation lines, fertilizer systems, etc., and are generally used at the rate of 1-5 parts per million. The rhodamine and uranine dyes are especially well suited for tracing since they are also fluorescent and can be detected with black light.
These specially selected dyes are intended for use in dyeing industrial products where color stability in acidic environments (pH<7) is critical. Acidic (Low pH) product (pH<4)
For use in dyeing industrial products where color stability in alkaline (pH>7) environments is critical.
Dyes can be added at varying concentrations to produce shades ranging from light to dark. Dye concentration is usually stated as a percentage based on the weight of the antifreeze. The following use rates represent typical applications for dyes in powder form. Blue, green and violet shades generally require less dye than do red, orange and yellow shades. Deep red shades require high use rates.
Robert Koch Industries' line of solvent dyes are soluble in oils, fats, waxes, resins, hydrocarbons, non-polar solvents, and to a lesser extent, alcohols. Solvent Dyes are insoluble in water.
Basic dyes are cationic (positively charged) dyes with excellent solubility in water and moderate solubility in many glycols and alcohols. These dyes are high in color strength and have characteristically brilliant color, including many beautiful fluorescent shades. Basic dyes are widely used in many applications.
We offer the following FDA certified colors for use in industrial and craft applications. We do not currently provide FD&C colorants to the food, cosmetic or pharmaceutical industries. FD&C dyes offer many advantages in technical applications, including high purity levels and low toxicity.
Absorption dyes are specially selected anionic dyes used to systemically dye fresh cut flowers and foliage. These water soluble dyes
Products suitable for dyeing with our immersion dyes include:
Dried flowers and foliage such as caspia, statice, broom bloom
Decorative foliage such as leaves and mosses
Materials derived from vegetable fibers such as raffia, jute, straw and various grasses
Wood products such as excelsior, paper, baskets, and potpourri products like wood chips and curls
High Lightfast (HLF) Solvent Dyes for Polar Solvents and Alcohols are metal complex-solvent soluble dyes. These dyes are soluble in polar organic solvents such as methanol, ethanol, acetone, MEK, etc. The dyes are characterized by:
Superior Lightfastness and Heat Stability
Good Resistance to Chemical Attack
Very High Dye Purity
