Cosmonate PI (Ortho-rich MDI) is a pure monomeric methylene diphenyl diisocyanate (MDI) with 45-55% 2,4’-isomer content. It is a light-yellow, solvent-free liquid at 20-35°C with an isocyanate functionality of 2.0. Cosmonate PI's slower reaction rates with polyols and increased working times enhance compatibility with polyol components. It is used in non-foam polyurethane applications, such as prepolymers for coatings, adhesives, sealants, and flexible and semi-rigid polyurethane foams.
