Acid donor and pH sliding agent
Acidon-PA is specially developed acid donor, based on sliding pH principle. Acidic pH is obtained with increase in temperature unlike conventional buffer which maintains pH irrespective of temperature. Acidon-PA is used for dyeing of polyamide, wool and their blends with acid dyes. Acidon-PA can be dosable.
| Key Features | Benefits |
|---|---|
| Sliding pH system
|
pH changes from neutral to acidic with gradual increase in temperature to 100 deg.C and maintains during the dyeing process
|
| Exhaustion | Better exhaustion and migration of dye by sliding pH
|
| Controlled dye-bath exhaustion | Not affected by dyebath auxiliaries |
| Stable to shear force | Applicable in soft flow/jet dyeing machine |
| Concentrated | Moisture content less than 1% |
| Physical appearance
|
Colourless liquid
|
| Ionic nature | Nonionic |
| pH of 1% solution | 4.5 +/- 1 |
| Miscibility | Miscible with water |
| Compatibility
|
Compatible with anionic, cationic and non-ionic products; stable to electrolytes
|
| Stability
|
Stable to dilute acids, dilute alkalies and hard water
|
Note :
Initial pH of dyebath along with Acidon-PA should be between 7-7.5
Precautions
Storage: Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature sunlight should not exceed 35 deg C. Close lids firmly to avoid contact with air and moisture
Shelf Life: 9 months from the date of manufacturing, if stored under controlled conditions.
