MAS Colloidal Silica – Sag-Resistant Structural Epoxy Filler
MAS Colloidal Silica is a high-density thickening filler for epoxy. Mixed into MAS 2:1 Non-Blushing or Traditional Marine epoxy, it controls flow and stops runs on vertical and overhead joints, and it turns resin into a hard, strong paste for structural bonding, filling and filleting. Mix the resin and hardener thoroughly first, then stir in silica until you reach the consistency you need.
