Filler Compound

Gateway Composites 777 is a two-part, epoxy adhesive filler compound used to fill voids, crack repair and other concrete applications requiring high physical properties. Gateway 777 is designed for bonding applications requiring resistance to abrasion and erosion, as well as acids, bleaches, alkalis, solvents and other corrosive chemicals. Gateway 777 is especially suited for use in applications requiring high bond strength, physical properties and good chemical resistance.

  • Use trowel or mixing stick and blend thoroughly 1-2 minutes until uniform color is achieved.
  • Mix no more resin than can be applied within the work period.
