High molecular weight methacrylate (HMWM) is a relatively new monomer that has many of the advantages of methyl methacrylate (MMA), namely low viscosity, potential for curing over a wide range of temperatures and good wetting characteristics. However, the HMWM has low odor and a high flash point which are signigicant improvements over MMA.HMWM has been used to produce polymer concrete for overlays and other specialty applications. It has very good mechanical and durability properties, and bonds very well to portland cement concrete.One of its most important uses, however, is to seal cracks and restore structural integrity of portland cement concrete. Due to its excellent wetting characteristics, it penetrates even very fine cracks. It has been used for a wide range of crack repair applications in the United States, particularly for bridges.
