Urethan

Part of speech: noun

Definitions

1. A synthetic resin or polymer commonly used as a coating or adhesive known for its toughness and elasticity ; a chemical compound derived from isocyanates and polyols used in manufacturing foams, elastomers, and coatings ; a durable plastic material utilized in construction, upholstery, and sealants prized for resistance to abrasion and impact
2. A versatile polymer formed by reacting diisocyanates with polyols, often applied as paint finishes or cushioning foam ; a tough and elastic compound favored in industrial manufacturing for making binders, coatings, and flexible materials ; a resilient synthetic material used to create protective coatings, adhesives, and soft foams for a variety of products
3. A class of polymers produced through a chemical reaction yielding materials with flexible, strong properties used in adhesives and coatings ; a durable substance formed from organic compounds serving as sealants, foams, and surface finishes ; a rubber-like material valued for its resistance to wear and its versatility in industrial and commercial applications

Etymology: Jean Baptiste Dumas, the French chemist, coined the name in 1833 in his "Recherches de chimie organique," published in the Annales de Chimie et de Physique. The word was built from pieces of older chemical names. Etymologists generally read it as a blend of "urée" (urea) and "éther" (ether), with the "-ane" ending borrowed from the naming pattern for hydrocarbons such as "méthane" and "éthane," which made the new term sound like a member of that family. The compound was a deliberate invention, so no earlier usage or folk story sits behind it. The "urea" part points to its origin in the study of urine-derived compounds, while "ether" reflects its structure as a derivative of an ether-like molecule. Read together, the name records two chemical families that Dumas was working between when he named it.

Synonyms: urethane, carbamate
