Pure MDI Prepolymer

Lupranate 5020 Isocyanate is a low free-NCO prepolymer based on pure MDI. The 9.5% free-NCO of Lupranate 5020 Isocyanate lends itself to one-component applications, such as but not limited to, moisture cure sealants, binders and coatings. In addition, the low free-NCO of this prepolymer helps reduce shrinkage in cast elastomers and one-shot systems.
