Sikadur Crack Fix
Sikadur Crack Fix is a two-component, 100% solids, moisture-tolerant low-viscosity high-strength epoxy adhesive in a single caulk-tube cartridge for gravity-feed and low-pressure crack injection. Part 770776 mixes 2:1 through a static mixer, holds a pot life of approximately 25 minutes, and viscosity is approximately 375 cps. At 73 F neat compressive strength reaches approximately 6,000 psi at 1 day and 13,000 psi at 28 days. It conforms to ASTM C-881 and AASHTO M-235.
