Surface Tension Reducer
CAS Number: 78-51-3
Fluorosurfactant-based surface tension reducer that dramatically lowers the surface tension of waterborne coatings and inks to ensure complete substrate wetting and spreading. It enables uniform film formation on low-energy substrates such as plastics, metals, and glass. Used at very low levels, it does not impair film clarity or recoatability.
