What is desmodur?

Desmodur is a family of polyisocyanates used in the production of polyurethane coatings, adhesives, and plastics. It is made up of aromatic and aliphatic isocyanates, which react with hydroxyl-containing compounds to form a urethane linkage. Desmodur offers high-performance mechanical, thermal, and chemical resistance properties to the resulting polyurethane products. It is known for its fast curing time, high durability, and excellent adhesion properties. Desmodur is used in a wide range of applications, including automotive, aerospace, construction, and electronics manufacturing. It is commonly available in liquid or solid form and is typically used in combination with a polyol to form polyurethane products. Desmodur is produced by various chemical companies, including Covestro, BASF, and Wanhua Chemical.
