Application

SURFACE PREPARATION: Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove surface contaminants, e.g. dust, grease, curing compounds, impregnations, waxes, foreign particles and disintegrated materials.

MIXING: Pre-mix each component thoroughly. Place 2 parts by volume of component A and 1 part by volume of component B into a clean pail. Mix thoroughly for 3 min. with low-speed drill or Jiffy type mixer (400-600 rpm) until uniformly blended. Mix only the quantity that can be used within its gel time.

TO BOND FRESH CONCRETE TO HARDENED CONCRETE: Apply by brush, roller, broom, or spray to cured concrete substrate. Place fresh concrete while SLOW SET BONDING AGENT is still tacky. If coat of SLOW SET BONDING AGENT loses tackiness, before pouring concrete, roughen epoxy surface to create a bonding profile. Recoat with additional SLOW SET BONDING AGENT and proceed.

TO BOND OLD TO OLD CONCRETE: Apply the neat SLOW SET BONDING AGENT with brush, roller, broom, or spray to the substrate working in for positive adhesion. While coating is tacky, join the coated substrates and secure firmly into place. Glue-line should not exceed 1/8 in./3.2 mm.

TO PROVIDE CORROSION RESISTANCE TO STEEL: Clean steel with abrasive blast or power tool to a white metal finish, either SSPC-SP-11 or SP-5. Spray or brush a coat of SLOW SET BONDING AGENT on steel to point of rejection, leaving no voids, pinholes, or uncoated areas. Coating should be approx. 20 mls. thick. Allow to cure to tacky stage and immediately pour concrete.

Limitations

Cleanup

EQUIPMENT: Uncured material can be removed with Unitex CITRI-CLEAN or other approved solvent. Cured material can only be removed mechanically.

MATERIAL: Collect with absorbent material. Flush area with water. Dispose of in accordance with local, state and federal disposal regulations.

First Aid

EYE CONTACT: Flush immediately with water for at least 15 minutes. Contact physician immediately.

RESPIRATORY CONTACT: Remove person to fresh air.

SKIN CONTACT: Remove any contaminated clothing. Remove epoxy immediately with a dry cloth or paper towel. Solvents should not be used as they carry the irritant into the skin. Wash skin thoroughly with soap and water.

CURED EPOXY RESINS ARE INNOCUOUS.
