Lanxess presents new low monomer urethane prepolymers




Lanxess presents new low monomer products for adhesives & sealants. With its Adiprene LF products the Urethane Systems business unit brings unparalleled performance and industrial hygiene to cast elastomers, coatings, adhesives & sealants applications. The company is a leading innovator in the development of low free (LF) isocyanate technology, on which the products are based.
“The focus of our development work is to broaden the range of prepolymers with very low free isocyanate content and to keep reducing the maximum amount of free isocyanate content,” said Dr Markus Eckert, head of urethane systems.
The Adiprene LF product range has been extended to include grades with less than 0.1 percent free MDI (methylene diphenyl diisocyanate) for adhesives and sealant applications. These new LF prepolymers offer three key benefits:
  • Improved industrial hygiene
  • Excellent performance
  • Better processing and increased productivity
Improved industrial hygiene
Adiprene LF urethane prepolymers minimize potential exposure to free isocyanate, a subject of increasing regulatory focus. Lanxess is the only manufacturer offering LF urethane prepolymers with levels of free isocyanate below 0.1 percent across a wide range of chemistries, including MDI, IPDI, HDI, TDI, and pPDI. The specialty chemicals company is constantly working to broaden this offering even further.
