PAPERMAKING CHEMICALS
Wet Strength Agents
Wet Strength Agents
These products provide strength to the paper when it is wetted, this is called wet strength.
They are used many grades of paper such as sanitary tissues, currency and packaging applications.
WET STRENGTH RESIN WS Series
- These agents are used in many grades of paper (household paper products, paperboard etc.).
- Due to their highly cationic nature, they can help retain anionic additives.
- Show a superior effect in high wet strength resin(WS) additive range by combination with DS or DA series.
