Bayer MaterialScience (Leverkusen, Germany) has developed raw materials for highly transparent two-component polyurethane casting compounds that can be used to manufacture lighting strips and other lighting elements with LEDs. The LEDs are given effective and long-term protection against moisture, weathering, and cleaning agents by being integrated into the elements. The casting compounds are formulated from solvent-free, aliphatic Desmodur® grades and solvent-free Desmophen® grades. The consistency of the casting compound can be adjusted from highly flexible to very hard, which allows production of high-quality lighting elements for a wide range of applications.
