From an etymological standpoint this is true. From a chemical standpoint, it is a polymer chain of urea molecules linked through alkyl groups via the nitrogen in the urea. It's not just many solid particles from urine mixed together. It's an elastomer...which means stretchy...that is used as a copolymer with polyurethane in Lycra.

As others have said, however, there's nothing really special about the Lucas product...at least not as far as bicycles are concerned.
