Durapatch™ MMA
- Chemical Family
- Methacrylates
Durapatch mMa is a two component, methyl methacrylate based concrete patching material. Durapatch mMa sets very rapidly to minimize downtime or traffic disruption. When mixed, Durapatch mMa forms a durable polymer concrete which bonds tenaciously to the concrete substrate and develops very high compressive strength. Durapatch mMa resists freeze thaw damage and has excellent chemical resistance.

- Usage
Rehabilitation of bridge decks, airport runways and expansion joints; Cold weather patching; Industrial and commercial concrete repair application where quick turnaround is important; Chemical resistant patching applications such as in chemical / food processing or containment areas; Areas where high strength patching is required such as loading docks, high traffic aisles, tipping floors or floors subjected to steel wheel traffic
- Cleanup
When operations are completed or interrupted for more than 15 minutes, the mixing vessel and application tools must be cleaned. Clean tools and equipment before mate-rial dries and sets with xylene, xylol or the Part A monomer of the Durapatch mMa kit. If the monomer is used for cleaning, it can be saved and used for the next mix or saved for future cleanings. Adding coarse aggregate to the mixer while cleaning aids in removing the polymer con-crete.
- Markets
- Building & Construction
- Storage
Store factory sealed containers of unmixed ma-terial at 50° to 75°F temperatures away from direct sunlight and sources of heat. Temperatures in excess of 75°F cause premature aging of the material. Shelf life of properly stored material is one year from date of manufacture.
- Advantages
Cures rapidly for emergency repairs in high traffic areas; Superior compressive, tensile and flexural strengths; withstands high levels of abrasion and impact loading; Excellent bond to existing concrete; Optimum flexibility to withstand vigorous thermal cycling; Freeze thaw resistant; Excellent resistance to acids and alkalies; Exceptional ultraviolet light stability; Can be extended with up to 20 pounds (9 kg) of 3/8" washed dry pea gravel or used neat
- Applications
Use a mason's trowel or steel finishing trowel to place and compact mortar into voids to be filled. Deeper areas may be vibrated to properly consolidate the material. Larger ar-eas can be topped by spreading with a short pronged rake. Do not featheredge the material. Caution must be taken due to the rapid setting time of ma-terial. Do not overwork the surface.
- Limitations
Durapatch mMa is exothermic, generating a large amount of heat when initially mixed. After mixing imme-diately pour all of the material into the area to be patched to dissipate the heat.; It is important to use all of the Part A Resin and Part B Aggregate provided.; Durapatch mMa is extremely fast setting. Substrate must be completely prepared and ready before material is mixed.; Good ventilation of the repair area is recommended to aid in the thorough cure of Durapatch mMa.
