Storage

Store in the original sealed container.
Recommended storage temperature: 6–28 °C.
Use within 6 months from the production date.
Avoid direct sunlight and contamination by acids, alkalis or other substances.

Prolonged storage at low temperatures may cause irreversible damage to the product. Keep the container sealed; otherwise, water evaporation will form an insoluble polymer film on the surface. Expiration of the 6-month shelf life does not mean the product is out of specification. Test before use to verify compliance with specifications and technical parameters.

Precautions

Adding a curing agent can improve fastness but may affect hand feel.
Waterborne resin added with crosslinking agent must be used within 24 hours.
Do not mix with other cationic resins.
