Product Introduction
1. The cohesive agent Seeyon®N-350 is an N,N-dimethylacetamide (DMAC) solution of an anionic dialkyl succinate sulfonate.
2. The cohesive agent Seeyon®N-350 is used in the polyurethane elastic fiber (spandex) industry to enhance the cohesion and adhesion between spandex filaments, reduce the volume resistivity of spandex filaments, improve their toughness and enhance their antistatic performance.
