What is desmodur used for?
PUs based on Desmodur® are used in upholstery, mattresses, car seats, thermal insulation (buildings, refrigeration), wheels, rollers and dashboards.
What is blocked polyisocyanate?
Blocked isocyanates are organic compounds that have their isocyanate functionality chemically blocked to control reactivity. They are the product of an isocyanate moiety (nearly always a di-isocyanate) and a suitable blocking agent.
What is desmodur?
Desmodur I is a monomeric cycloaliphatic diisocyanate. It is suitable for use in the manufacture of polyisocyanates and polyurethanes. It is also known as 3-isocyanatomethyl-3,5,5-trimethylcyclohexylisocyanate or isophorone diisocyanate (IPDI).
Is isocyanate in polyurethane?
Polyols and isocyanates are the core components in the production of polyurethanes. The chemical structure and functionality of polyols and isocyanates are expected to affect the properties of polyurethanes.
What is isocyanate used for?
Isocyanates are a family of highly reactive, low molecular weight chemicals. They are widely used in the manufacture of flexible and rigid foams, fibers, coatings such as paints and varnishes, and elastomers, and are increasingly used in the automobile industry, autobody repair, and building insulation materials.
How is isocyanate made?
Isocyanates are usually produced from amines by phosgenation, i.e. treating with phosgene: RNH2 + COCl2 → RNCO + 2 HCl. These reactions proceed via the intermediacy of a carbamoyl chloride (RNHC(O)Cl). Owing to the hazardous nature of phosgene, the production of isocyanates requires special precautions.
How is isocyanate produced?
Is isocyanates a hazardous material?
Isobutyl Isocyanate is a colorless liquid with a pungent odor. It is used in making other chemicals and pesticides. * Isobutyl Isocyanate is on the Hazardous Substance List because it is cited by DOT.

How do you protect from isocyanates?
Use personal protective equipment, including proper gloves, goggles, full-face shields, and respirators. Skin protection and ventilation are the most important factors to protect your health against isocyanate exposure.
What will dissolve expanding foam?
You can use a solvent such as acetone or nail polish remover to dissolve it when this happens. If you do not have acetone, then a lacquer thinner or gasoline will work as well.
