Film-Forming, Self- Crosslinking, Aqueous Superabsorbent Coating

Aqueous Superabsorbent Coating (ASC) technology is a liquid polymer solution that dries to form an absorbent film. It can absorb up to 40 g/g by weight of water, depending on the chemistry used, and can absorb water vapor from the air up to 70% by weight. Tests have demonstrated a greater absorbency of fluids containing proteins than cross-linked sodium polyacrylates (ASC 8-10g/g versus SAP 6g/g). The material can be “dried” after hydrolysis with exposure to air at moderate temperature.
