Desmodur® XP 2406

Covestro (formerly Bayer MaterialScience) 科思创

Desmodur® XP 2406 is an aliphatic polyisocyanate prepolymer based on isophorone diisocyanate that is used as a binder for the formulation of flexible surface coatings and sealers. This product has an isocyanate content of approx. 2.8%, a monomeric IPDI in supply form of < 0.5%, a non-volatile content of approx. 80%, a viscosity at 23°C of approx. 7,000 mPa·s, and a hazen color value of max. 200. Desmodur® XP 2406 can be combined with Hardener® VP LS 2959 to formulate moisture-curing coating and sealing systems for large surfaces. The formulations are characterized by their very good storage stability and dry in thick coats to yield blister-free films. The films yielded by coatings based on Desmodur® XP 2406 are flexible, also at low temperatures.
