• Reduces thermal shrinkage through slow expansion
• May close concrete cracks through self-healing
• Increases wet adhesion in tile adhesives
• Increases mechanical strength

Namex XA is a unique modified magnesium oxide that expands with water to counteract thermal shrinkage in concrete.

To the contrary of most magnesium oxides Namex XA has been given a reactivity that will allow it to be fully reacted in 90 days.

The reaction is topomorph (local and not through a dissolution process) and does not influence the quality of the product to which it is added.
