【Quality specification】
　

【Application】
This product is used in wet process of tannery as leather chemicals. It is stable in the solutions of formic acid, acetic acid and ammonia. Its function can be strengthened when it is in acid solution，which improves brighten and color-fixing effect. Besides, its flocculation settling in treating dyes wastewater can greatly reduce the residual dye in the wastewater and decrease the tannery’s burden in wastewater treatment to protect environment.
【Use】
Please first have a small test to confirm the correct method and dosage.
Reference method and dose: Normally, before dyeing, increase 0.5-1.0%, pH of staining solution should be 3-6. Increase appropriately and process color-fixing and oil-fixing When it is combined with the formic acid before finishing Fatliquor and color-fixing.
