Polycaprolactone polyol, diol, triol, for polyurethane sealant
MDI (Isocyanate) introduction :
Cosmonate M-200 is polymeric MDI, generally used in manufacturing hard and semi-hard polyurethane foam. Cosmonate M-200 is liquefied in normal temperature and easily handled and stored down to -20ºC. It is solvent-free form with 2.7 average organic function and maximum of 125 cps (25ºC) viscosity which is mixed with monomer MDI of 4,4-diphenylmethane diisocyante and its oligomer above dimer, trimer and tetramer.
