Gilsonite is useful in bitumen mastic sealant becuase
  • Gilsonite is an effective alternate for high cost, end block resins for Kraton
  • Strong bonds broke concrete over 10% to 90% of the bond area
  • Viscosity adjustments are necessary to obtain “gunning” grade consistency

Sample Preparation

Kraton and the resin were dissolved in warm solvent. Prewetted filler was then mixed into the rubber/resin solution. Bonded specimens were dried for 5 days at 23°C prior to testing. Suggested Uses of Gilsonite Broad range application for bonding wood to wood, wood to dry wall, masonry to wood, and wood to glass and metal.
