Concrete Metal Bonder

CMB (Concrete Metal Bonder), formerly known as C2M (Concrete to Metal), serves as a robust bonder between new and old concrete, or between new concrete and metal such as steel rebars. It solves two major bonding challenges:  bonding new and old concrete, and bonding newly added concrete with hardened rust on rebars.

The pull-forces on CMB’s bonding surpass the maximum pull forces of most materials it bonds. While CMB is commonly used alongside Maxon’s primary corrosion neutralizing products (MCN and CEN), it possesses anti-corrosion capabilities of its own. 

CMB (Concrete Metal Bonder) is:

  • Eco-friendly and toxic-safe, with a VOC level below 24 grams/liter

  • Resistant to UV, abrasion, and freeze/thaw conditions

  • Broad performance range for thermal, salt, fog, and humidity

  • Cleans up easily and quickly with just water

  • Highly flexible, capable of bending 900 without cracking


CMB is produced in the USA

Description

MAXON Technologies CMB is a dual component system, consisting of CMB Emulsion, a uniquely blended binding agent, and CMB Powder, a super-fine specialized cement powder. CMB has the ability to bond with metal surfaces and provide a surface coating that encases and protects old deteriorating, ferrous products. CMB contains various anti-corrosion agents and superior bonding strength. High adhesion = high corrosion resistance.

CMB is a universal coating which can be used as a primer base coat as well as a top coat depending on project requirements. When properly applied, CMB provides both the applicator and asset owner with a cost-effective infrastructure maintenance program. CMB is environmentally friendly due to its use of recycled industrial material, extremely low VOC level, and ease of application and use. CMB has an advantage over other coating systems by providing asset protection against many freeze/thaw, chemical and abrasion threats.

NOTE: Maxon CMB is not a structural or restorative product and should only be used on substrates that are structurally sound.

Basic Usage

The primary use of CMB is to protect and restore ferrous materials from deterioration or further loss of structure through exposure to many naturally occurring elements. CMB also provides a unique method to bond metal substrates to concrete. Some common use-cases include:

  • Concrete Encased Metal
  • Metal Stairs and Ramps
  • Corrosion Under Insulation (CUI)
  • Exhaust Systems
  • Corrugated and Metal Roofs
  • Rebar
  • Steel Structures
  • Boilers and Furnaces
  • Metal Doors
  • Pipe Exteriors

Maxon Technologies CMB can be used in some cases as a stand-alone solution, although more often as a part of a more complex solution utilizing other Maxon Technologies' products.

Additionally, CMB may also be used as a functional primer or top-coat in other coating systems.
