MAS Epoxy Colloidal Silica Filler forms an extremely hard, high-density solid when added to resin — built for structural bonding, filling, and filleting.
Structural filling and bonding
Used alone as a filler, MAS Colloidal Silica forms an extremely hard, high-density solid, making it well suited to structural bonding, filling, and filleting work.
As a fairing agent
Colloidal silica (cab-o-sil) also works well as a fairing agent, helping to hide and blend repairs on GRP boats.
Recommended hardener
MAS recommends using Medium hardener with FLAG resin when bonding, filling, and filleting with this filler.
