MM-80 is a two-component, 100% solids content epoxy joint filler. When cured, MM-80 is a gray, semi-rigid (hard but slightly resilient) filler with a Shore hardness of A90-95.
MM-80 was developed to fill and protect joints in industrial concrete floors that are subject to hard wheeled material handling traffic and heavy loads. Its primary function is to support such traffic and protect joint edges. MM-80 is designed for use in areas where final temperatures are from 40¢ªF (10¢ªC) to +120¢ªF (49¢ªC). It is also ideal for joint and crack repair.
