  • Half gallon size of talc thickener for resins, easier to sand than fumed silica. NOT for use below the waterline!
  • The talc is used with AeroMarine epoxies to thicken the resin for above water applications.
  • It is a low cost filler for thickening polyester and epoxy resins but it can add significant weightto your project.
  • We recommend pre-measuring the resin and hardener and mixing the talc inwith the resin prior to adding the hardener to save your work life.
  • Once the talc is thoroughly mixed into the resin add the hardener.
  • Do not use talc with urethanes as it can hold moisture.
