CAS No. 17526-94-2
Molecular Formula: C13H20N4O2
Molecular Weight: 264.32
Synonyms: 1,1-(4-Methyl-m-phenylene)bis(3,3"-dimethylurea); Counterpart for Dyhard UR 500; Hardener & Accelerator for Epoxy Resin; Substituted urea accelerator
Description
KylinCure 500 is the most reactive blocked accelerator for Dicy - Epoxy systems allowing a long shelf life. Meanwhile, it provides with fast curing and high cross-linking density.
KylinCure 500 decomposes under heat to form NCO- (isocyanate-) groups and catalytically active dimethylamine. The dimethylamine accelerates the curing of the epoxy and the isocyanates react with epoxies to form additional linkages via oxazolidinones.
