Product Description

Composition
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.
Related Products
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.
Basic Use
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.

Advantages

MM-80's superior formulation yields sufficient rigidity to support
loads crossing joints, protecting edges from spalling, and sufficient
resiliency to prevent brittleness throughout the floor's life.
MM-80 exhibits low range tensile and adhesive strengths, characteristics
necessary to allow the joints to open as the concrete
shrinkage progresses.
MM-80's relative hardness has been gradually increased through
the years to reflect increasing demands on floors created by
heavier loads and smaller, harder vehicle wheels.
MM-80 is the joint filler upon which ACI and PCA standards are
based. You can specify and use MM-80 with the confidence that
comes from a project-proven track record of more than thirty
years and with the knowledge that you are relying on the best
floor joint protection available in the industry.
