Desmodur® LS 2424

Covestro (formerly Bayer MaterialScience) 科思创

Desmodur® LS 2424 is a monomeric diphenylmethane diisocyanate with high 2,4'-isomer content. It is used in the formulation of prepolymers for use in one- and two-component polyurethane coatings and adhesives and in related applications. Desmodur® LS 2424 is an isomeric mixture of monomeric diphenylmethane diisocyanate that is liquid at temperatures above 20 °C. Storage and handling are greatly simplified compared to 4,4' isomer that is solid at room temperature (Desmodur® 44 M, Desmodur® 44 MC). This product has a vapor pressure at 20°C (MDI) of < 10^-5 hPa, a phenyl isocyanate content of max. 10ppm, and a degree of purity (MG 250) of min. 99.5% by wt.
