Acid Donor  AG-52 Specification: Acid donor AG-52 makes the pH value of the dye bath slide and suitable for dyeing nylon and chlorinated mercerized wool. Acid donor AG-52 can be used in dyeing of mercerized wool and nylon on acid, reactive, mordant or metal complex dyes. Acid donor AG-52 makes the pH value of the dye bath slide from neutrality to acidity   Ingredients:      Organic mixed acid esters   Properties:  

Appearance	Colourless to Pale yellow transparent liquid
Iconicity	non-ionic
Solid content	99.5±0.5%
Solubility	soluble in any ratio of water easily
pH value	3~4
Chemical stability	Has good stability to hard water, salt and acid but easy to arise hydrolysis in alkali

  characteristics:       Acid donor AG-52 is an acid gradient, with the increasing of temperature, the organic acids is released gradually, so the PH value of dye bath reduced slowly . When using AG-52, the pH of dye bath will get lower as temperature rises and the dyes absorption speed could be controlled. Through this, it will be able to obtain good leveling and reproducibility; Because the pH value of water differs. When using this product, please adjust the pH of water to weak alkaline first. After adding this product, the dye bath willturn into acidity automatically as temperature rises; Solves the uneven dyeing problems caused by fast dyes absorption; Acid donor AG-52 can be used in dyeing of mercerized wool and nylon on acid, reactive, mordant or metal complex dyes low foaming ability; excellent stability to hard water, salt, and but easy to arise hydrolysis in alkali. no slide effects to light, wet, rubbing fastness. green,environmental protection,excluding APEO.    Application:        Acid donor AG-52 can be used in dyeing of mercerized wool and nylon on acid, reactive, mordant or metal complex dyes.     Method of use        After diluted with water,according to the amount of use occasions between 0.5 ~ 1.0g/l . Packing and storage:       1. 50kg or 120kg in one plastic drum;     2. can be storage for 12months,at room temperature and in cool and dry palce;     3.The product is non-hazardous,chemical properties stability,canbe used in any mode of transport.   Remarks:      All technical information quoted above is based on our experience, but it is only for reference of using this product and not given with guarantee and obligation.
