Epoxy Curing Agent Counterpart for Dyhard UR 500

KylinCure 500 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.   Applications Laminates for electrical circuit boards …
