Bonding Agents

Now it’s possible to bond any material, counting concrete itself, firmly and also permanently to a hardened concrete surface. Such bonding, using epoxy-based “glues”, becomes as strong, and also frequently stronger, than could be gained by any mechanical means of connection. These glues or Bonding Agents are made up of 2 liquids- a base resin and a curing agent (or hardener) that are mixed immediately before use.

3 factors would influence the end properties of a bonded joint:

• Right choice of resin grade and hardener
• Proper surface preparation
• Careful application.

The epoxy based compounds would have very high strength at a very early age and also extreme chemical resistance, which measures that a bonded joint would remain unaffected by environmental contamination.

The strength of a bonding joint in the case made correctly would always far exceed that of even the best quality concrete. The flexural power of concrete, for example, would lie in the 600 to 800 psi range; a typical cured resin, on the other hand, would show a cross-breaking strength of around 5,800 psi, which means that any breakage might occur through the surrounding concrete rather than through the joint.

It always means, however, that a contractor would not expect too much from a Bonding Agents remember that in case a resin with a tensile power of 2,000 psi is used to join 2 concrete slabs each having a tensile strength of 300 psi, the effective power of the bonded until is still just 300 psi.

When dealing with epoxy bonding, however, remember that is beneficial to consult the manufacturer’s technical representatives before starting a job.

• Forms a superb bond to concrete.
• Offers superior flexural, adhesive, and also impact powers and also outstanding abrasion resistance.
• Delivers a tough, durable finish at a far lower cost than polishing or rubbing.
• Will not after yellow.
• Will not stain or discolor concrete.
• Prepared to use, needs no additional mixing.
• Decreases permeability.
