RESIN FILLERS make resins more versatile
A general note about fillers: Microspheres, Silica and Fiber fillers can all be used as thickening agents in epoxy resins to use as adhesives. It is also possible to use any of the fillers for making fillets, however, only SILICA will prevent sagging. By experimentation you may find filler combinations that better suit your specific needs. Remember that regardless of how much of the fillers you use, the resin to hardener ratio remains the same.
