Paper Wet Strength, Dry Strength & Sizing Agents
Paper performance is built with three additive families: a wet strength agent (PAE resin) for strength when wet, a dry strength agent for tensile/burst strength, and a sizing agent for water/ink resistance.
The three families
- Wet strength: PAE wet strength agent — keeps tissue and packaging strong when wet.
- Dry strength: polyacrylamide-based agents raise tensile and burst strength.
- Sizing: AKD/ASA and rosin sizes give water and ink hold-out.
On the machine
Added at the wet end (machine chest) or size press; dosage is set per ton of paper. See our paper chemicals.
Frequently asked questions
What is a wet strength agent in paper?
Most commonly a PAE (polyamideamine-epichlorohydrin) resin that lets paper and tissue retain strength when wet.
What is the difference between wet strength and dry strength agents?
Wet strength agents preserve strength when the paper is wet; dry strength agents increase tensile and burst strength of dry paper.
