LUBIO® Additive

Isocyanate Cross-Linkers

The LUBIO® Polykat series comprises different phospholene oxide derivatives CAS 31563-86-7 (e.g. 1-methylphospholene-1-oxide) which facilitate the cross-linking of isocyanates to carbodiimides. Depending on the LUBIO® Polykat type the isocyanate cross-linking takes place with a temperature between 50 and 150°C. The individual LUBIO® Polykat types vary with regard to reactivity and selectivity. Subject to the LUBIO® Polykat type both aromatic and aliphatic isocyanates can be transformed to carbodiimides.
