Vanconol® LFS-1900 Series Low Foam Surfactant
1 🎯 Abstract
Vanconol® LFS-1900 Series are low foam surfactants, composed of a mixture of acetylenic diol and isomeric alcohol polyether. They possess excellent dynamic surface tension, low foam, permeation, emulsification, dispersion and washing properties, serving as outstanding emulsifiers with powerful emulsifying ability. Stable to acid and alkali solutions, they have strong compatibility with other nonionic and anionic compounds, suitable for cleaning and printing formulations requiring low foam.
