SINOMER® PM840-M15 is a modified polymercaptan curing agent. When mixed with epoxy resins (such as BER-128/E51) at a 1:1 ratio, it achieves rapid gelation and curing even at low temperatures and in thin films. It demonstrates significant advantages in rapid repair, winter construction, and low-temperature operations. This grade can rapidly cure standard epoxy resins within 15 minutes, ensuring high adhesion strength.
