SpecPoxy Binder Green Conscious Product

ASTM 881 compliant low-mod, epoxy binder/adhesive

SpecPoxy Binder is a two-component, multi-purpose, low-modulus, moisture-tolerant epoxy binder adhesive. It meets ASTM C881 requirements and can be used as a multilayer, waterproof, skid-resistant polymer overlay system for bridges and parking decks. This low-viscosity binder is solvent-free and offers flexibility to sustain movement due to thermal changes.

  • Low Modulus, High-Strength Adhesive: Meets ASTM C881 requirements.
  • Moisture Tolerant: Can be applied in damp conditions.
  • Flexible: Capable of sustaining movement due to thermal changes.
  • Waterproof/Skid-Resistant Surfaces: Creates impermeable surfaces that are also shock-absorbing.
  • Easy Aggregate Blending: Ideal for mortar repairs, allowing easy blending of aggregates.

Application

  • Epoxy Mortar: Mix 3.5 – 5 parts clean dry silica sand to 1 part of mixed SpecPoxy Binder.
  • Mortar Overlays/Patching: Clean and prime the substrate with neat SpecPoxy Binder, then apply the epoxy mortar while the primer is still tacky.
  • Broadcast Overlays: Apply neat SpecPoxy Binder with a 3/16” notched squeegee, then broadcast clean, dry aggregate to rejection.

Mixing Instructions

  • Ready-to-Use: Do not thin with any solvents.
  • Temperature Requirements: Air, material, and surface temperatures must be at least 40°F prior to mixing or installation.
  • Mixing Process: Premix each component separately, then mix 1 part of Part A with 1 part of Part B for three minutes using a low-speed drill.

Surface Preparation

  • Ensure surfaces are clean and structurally sound.
  • Remove all oil, grease, dirt, laitance, curing compounds, and other foreign materials.
  • Optimal adhesion is achieved by creating an open profiled/roughened surface similar to sandpaper.

Packaging

  • Available in 1 gallon units, 2 gallon units, and 10 gallon units.

Shelf Life

  • Store in original tightly closed containers.
  • Shelf life is two years from the date of manufacture when stored properly.
