Properties

• Chemical nature: blend of organic and inorganic alkalis
• pH (3.5%): 12 - 13
• Solubility: 200 g/l in water at 20 °C
• Storage: at least 12 months in the closed original container, in a cool, dry place, between 5 and 25 °C
• Alkaline product: after contact with eyes or skin, rinse immediately with plenty of water

Uses

• Reactive dyeing: replaces sodium carbonate, trisodium phosphate and caustic soda and lowers the process cost
• Reduction clearing
• Scouring of polyamide, cotton, recycled polyester and other fibers. On polyamide and recycled polyester, start with 60% of the carbonate amount and check that the required pH is reached
• Machines with automatic bath feeding and low liquor ratio
• Add in three parts after reaching the fixation temperature: 10%, 30% and 60% of the total at 10-minute intervals, for a gradual pH change without leveling problems
• In dark shades, add more sodium sulfate at the start and/or 0.5 - 2 g/l caustic soda after the Alcali CDQ NEW
• Dissolve before adding to avoid lumps in the bath or the piping
