Levasil® CC301

Levasil® CC301 by Nouryon is a water-based epoxy silane-modified colloidal silica dispersion. Acts as a surface siccative agent for water-borne coating systems. The colloidal silica particles migrate to the surface of the paint during film formation inducing enrichment of silica, which in turn leads to improved film properties. It induces an extension of the open time for thickeners such as HM-PAPE, EHEC, HASE but the degree of extension varies between the thickening agents. One pack sol-silicate paints based on it are characterized by long term stability and enable concentrated formulations up to solid contents of 50 %wt.
