pH Buffers and pH Regulators

Pilbuffer 45

The product has an outstanding buffer capacity, which guarantees the highest possible pH constancy in dyeing baths.

• Ideal for polyester and wool dyeing
• No pH change through electrolytes and added substances to the dye bath, excluded acid or alkali.
• Stable in higher temperatures
• Easy and safe handling

Acro H-ET

Acid donor for polyamide dyeing.

• pH control during dyeing of PA and WO fibers and their blends with almost all dye classes at all stages of processing at boil and at HT conditions on a variety of dyeing equipment
• Gradually reduces the pH as temperature rises so that uniform build up and leveling of dyes hence excellent and reproducible

Pilnor DY

Alkaline donor for the use in reactive dyeing of cellulose. Pilnor DY is a chemical preparation mixture which can be used as a soda ash substitute.

• Uniform buffering capacity within the pH range of 11.5–12.0
• Excellent shade reproducibility and easy shade matching
• High stability at reactive dyeing temperatures, ensuring complete release of alkalinity for
• effective dye fixation on cellulose fibers
• Improved process reproducibility through precise pH control
• Reduced risk of stain formation
• Shorter dyeing time compared to conventional processes
• Higher dyestuff yield and improved fixation efficiency
