Sig Micro-Balloons are expanded glass beads, microscopic in size. They are so small, they have the appearance of powdered sugar and are extremely light.
They make a strong light weight putty when mixed with Sig-Ment, Sig Polyester Glass Resin, or Sig Epoxy Glue. Instructions for mixing are on the container.
The primary purpose of Micro Balloons is to expand and extend other adhesives in such a way that they can fill in voids or perhaps form things like wing fillets yet not be as heavy as solid glue or solid epoxy would be.
