Product Features
Diphenylmethane diisocyanate monomer with high 2,4'-isomer content, stable against storage discoloration.
Prepolymer formulations for 1K and 2K polyurethane coatings and adhesives and related applications.
Desmodur® 2460M is a mixture of isomers of diphenylmethane diisocyanate monomer, liquid above 20°C.
Easier to store and handle than the 4,4'-isomers (eg Desmodur® 44M, Desmodur® 44MC) which are solid at room temperature.
Supplied form is solvent-free, colorless to yellow low viscosity liquid above 20°C and crystallizes at lower temperatures.

Processing
It is imperative to ensure that all containers - including empty ones - are always airtight. Most importantly, since Desmodur® 2460M reacts with water to form polyurea and carbon dioxide, it must be protected from contact with water. During storage, sampling, transfer and processing of Desmodur® 2460M, moisture must be prevented from ingress in any form (wet containers, anhydrous solvents, moist air), otherwise, the carbon dioxide produced will lead to a pressure increase in tanks and containers high and dangerous. Furthermore, the formation of polyurea in Desmodur® 2460M may cause turbidity and solid deposits which can clog filters, pumps and lines.
