MM-80 is available in two versions; MM-80 with the original 5:1 ratio, used primarily for manual dispensing, and MM-80P, with a 1:1 mix ratio, intended for use in dual-component mechanized pumps.
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˚F (10˚C) to +120˚F (49˚C). It is also ideal for joint and crack repair.
