Points to be concerned:
1. After adding this product, it is necessary to promptly test the physical indicators of the paper surface such as absorption weight, and adjust the dosage in time to avoid production fluctuations and impact on paper quality.
2. This product is of cationic. It should be avoided to be mixed with strongly anionic additives such as CMC, anionic PMA, anionic dyes, and brighteners.
3. During storage, avoid mixing with other chemicals to prevent unexpected reactions.
4. When transporting or storing this product over long distances, keep it sealed to prevent water evaporation and surface skinning. Store it in a well-ventilated and cool place (4-30℃), avoiding direct sunlight and freezing, and use it within the product's validity period.
5. The shelf life of this product is 6 months.
Package
