About this item

  • Premium Thickener: Also referred to as colloidal or hydrophilic fumed silica, our silica thickener is an excellent thixotropic agent designed to help control the viscosity of mixed epoxy systems
  • Measure And Mixing: Mix the amount of resin, Part A, and hardener, Part B, desired, then add silica thickener in increments, and mix thoroughly, stirring from the bottom to the top until the desired consistency is reached
  • Features: This epoxy thickener easily mixes into epoxy resin systems
  • Consistency: Silica Thickener can be used alone to create a very smooth, non-sagging, high-strength mixture, but can also be combined with other fillers or fibers to prevent sagging
  • Cleanup: Clean hands, exposed skin, and work surfaces with mild soap and water
