CYANURIC CHLORIDES FOR DYES AND BRIGHTENERS
Cyanuric chloride is a multifunctional intermediate for herbicides, reactive dyes, optical brighteners and
many other specialties.
The cyanuric chlorides are used in the synthesis of optical brighteners. The bluish fluorescence generated
makes the yellow or yellowish substrates appear whiter. Cyanuric chloride is also an important raw
material for the production of numerous reactive dyes. The dye is chemically fixed on the fiber. The result is
a high-grade, non-fading, colorfast dyeing.
WeylChem Wesseling is able to offer a variety of different grades and supply forms of cyanuric chloride. All
products are of very high quality standard. Whether solid or liquid, we can meet all your requirements.

EXEMPLARY APPLICATIONS
OPTICAL BRIGHTENERS
These are compounds which absorb invisible UV-light and emit visible light primarily in the blue spectral range. The bluish fluorescence generated makes the yellow or yellowish substrates appear whiter. Optical brighteners are therefore used in detergents, for the finishing of textiles, and in the manufacture of highly refined paper.
REACTIVE DYES
Cyanuric chloride is an important raw material for the production of numerous reactive dyes. Reactive dyes form a chemical bond with cellulose, the main component of cotton fibers. Other fibers that have nucleophilic groups can also enter into a covalent bond with the triazine substituents: that is, the dye is chemically fixed on the fiber. The result is a high-grade, non-fading, colorfast dyeing.
UV-LIGHT STABILIZER
Cyanuric chloride is a main component in the synthesis of UV-light stabilizers, which are used frequently in plastics. The UV-light stabilizers are either UV-absorbers or radical scavengers. They improve the functional life time of plastic materials, and prevent discoloration and brittleness.
