Dow Chemical Company Files Two Patents for “Greener” Rubberized Running Surfaces

Rubberized surfaces are commonly used for running tracks, playgrounds, and playing fields, but until now, the use of a two-part polyurethane and silane-PU adhesive to bond rubberizing particles to surfaces and to one another has been the only option.

Rubberized surfaces are commonly used for running tracks, playgrounds, and playing fields, but until now, the use of a two-part polyurethane and silane-PU adhesive to bond rubberizing particles to surfaces and to one another has been the only option. As a result, VOCs from solvents, catalysts,and additives have raised concerns.

To overcome this, Dow Chemical Company has developed ECOGROUND, an adhesive that features water-borne, acrylic based technology. The water-borne binder bonds the tiny particles of rubber together, and the company says that no organic solvents, inorganic fillers, or additional additives need to be used during application and that its product will be compatible with machine sprayers and pavers as well as being suitable for manual application. At the end of its useful lifespan, the surface can be recycled.

Dow notes that recreation facilities are in demand in countries with high population growth, particularly India and China. China has uncovered health issues related to rubberized surfaces at schools and sports and recreation facilities during the last decade, and Dow says that ECOGROUND will offer a “clean” alternative. The company reports that ECOGROUND is compliant with the International Association of Athletics Federations’ requirements for rubberized surfaces.
