Sikadur®-732

2-component epoxy resin bonding agent

Sikadur®-732 is a solvent-free, 2-component bonding agent, based on selected epoxy resins. After application to old concrete surface, it provides a perfect bond for new concrete.
Sikadur®-732 complies with ASTM C 881-02, Type II, Grade 2, Class B+C.

Sikadur®-732 provides a bond of far greater strength than the tensile strength of the concrete itself. Therefore, it is suitable for use wherever structural bonding of new concrete to existing one is carried out.
Other benefits are:
  • Easy to apply
  • Solvent-free
  • Unaffected by moisture
  • Highly effective even on damp surfaces
  • Workable at low temperature
  • High tensile strength

Usage

  • To permanently bond freshly mixed mortar or concrete to hardened concrete, glazed bricks, tiles, steel or other structural materials.
  • Sikadur®-732 is also used to seal hair lines cracks and as a protective coating to steel parts i.e. anchor plates.

Application steps

SUBSTRATE PREPARATION

All surfaces must be clean, free from standing water and all loosely adhering particles. Cement laitance should be removed, by mechanical means (i.e. sand blasting).

MIXING

Mix both components together with a slow speed electric drill (max. 600 r.p.m.) until a smooth consistency is achieved.

CLEANING OF TOOLS

Clean all tools and equipment immediately after use with Thinner C.
