SpecPoxy 3000 FS

Fast-setting ASTM 881 compliant hi-mod, gel viscosity epoxy

SpecPoxy 3000 FS is a two-component, moisture insensitive, high modulus, structural epoxy bonding gel. This product is 100% solids, solvent-free, low odor, high strength, and non-sag, making it ideal for various structural bonding and patching applications.

  • Fast-setting with a gel time of only 10 minutes.
  • Can be used for both vertical and overhead applications due to its gel/paste viscosity.
  • ASTM 881 compliant for high-modulus applications.
  • Ideal for environments requiring quick turnaround times.

Mixing Instructions

  • Mix equal volumes of Part A and Part B for three minutes using a low-speed drill.
  • Ensure air, material, and surface temperatures are above 40°F (4°C) before mixing.

Surface Preparation

  • Surfaces must be clean, dry, and structurally sound.
  • Remove all contaminants by sandblasting, mechanical abrasion, or hydroblasting.
  • Ensure drilled holes are cleaned out with a nylon brush and oil-free compressed air.

Application Techniques

  • Bonding: Apply SpecPoxy 3000 FS neatly into the substrate and ensure the glue line does not exceed 1/8”.
  • Anchoring: For anchoring applications, prepare the holes and insert the bolts or dowels while the epoxy is still tacky.
