ABSTRACT:
An economical composition capable of maintaining satisfactory Durometer hardness is formed by reacting a polyol, a polyisocyanate, and an aromatic polyamine in the presence of an extender oil. The polyisocyanate can be present in a first container of a kit and the aromatic polyamine can be present in a second container of the kit. The resulting composition can be employed in a flat-free pneumatic tire as well as for filling cracks in the surface of a structure.
