DES-N aerosol has been shown to be primarily a pulmonary irritant following a single exposure in mice. Both of these sustainable raw materials are available in large quantities now and will be in the longterm future. Logistics and Handling. Equivalent. Two of the six possible isomers are commercially important: 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7). Desmodur ® N 3790, N 3300, N 3390 and N 3600 are all TSCA listed. Niklas von der Assen and André Bardow Green Chem. Background - Rubber-to-Metal Bonding. This section provides links to the list of precautions (precautionary statements) and to the guidance on safe use, if they have been provided in REACH registration dossiers. It should, however, be noted that these joining techniques have their advantages and disadvantages and the most ap-propriate method will depend on application and service requirements. Equivalent. It is suitable as the hardener component for lightfast polyurethane coating systems. Engineered rubber-to-metal devices enable key performance attributes for automotive, industrial and aerospace applications. The 4,4' isomer is most widely used, and is also known as 4,4'-diphenylmethane diisocyanate. functional speciation†.

Chemical structure: C8H12N2O2; Synonyms: Monomeric aliphatic diisocyanate can be also called Hexamethylene-1,6-diisocyanate or 1,6-diisocyanatohexane. IPDI-Trimer (one possible structure) Viscosity. ” Most commonly, generic TDI consists of an 80:20 mixture of the. It can be used in combination with various Desmophen®, Baycoll®, Desmocoll® grades or other hydroxyl-bearing substances to formulate two-component polyurethane coatings and adhesives. CAS 75-78-5, chemical formula (CH₃)₂SiCl₂. A slender cylindric structure or device. Property Name Property Value Reference; Molecular Weight: 479.
