MasterFiber M 70| Synthetic Monofilament Microfiber

How does MasterFiber M 70 concrete fiber additive work?

MasterFiber M 70 is a monofilament polypropylene fiber manufactured from 100% virgin homopolymer polypropylene resins. This residential concrete fiber additive meets the requirements of ASTM C 1116/C 1116M, Section 4.1.3, Type III, and Note 2 and the requirements of ICC ES AC32 Section 3.1.1 (plastic shrinkage reinforcement).

MasterFiber M 70 product disperses well in the concrete mixture, and visible evidence of a superior finishability makes it a good candidate for all residential concrete applications.

Recommended residential concrete applications:

Sidewalks
Decks
Patios
Residential driveways
Pool decks
Extruded curbs and gutter
Basement and garage floors
Stucco

What are the unique features of this monofilament fiber?

MasterFiber M 70 is formulated to meet key industry performance standards. Among concrete fiber additives, MasterFiber M 70 is an outstanding choice when a high-quality finish and minimal cracking are critical.
