$110.29

MM-80 is a 100% solids, two component, heavy duty semi-rigid epoxy joint filler designed to fill and protect contraction and construction joints in industrial concrete floors. 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).

Higher relative hardness for improved durability
Contains no VOC's, LEED compliant
Used widely for more than 45 years

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. Metzger McGuire 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 is also available in a silicone free version for use in paint and automobile facilities. Please contact us for more details.
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 forty-five years, and with the knowledge that you are relying on the best floor joint protection available in the industry.

MM-80 is acceptable for use in floors subject to inspection/ regulation by USDA/FDA and Environment Canada/CFIA. MM-80 contains no VOC’s and fully complies with all LEED green building standards.
