MasterFiber M 70

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.

• Meets the requirements of ASTM C 1116/C 1116M, Section 4.1.3, Type III, and Note 2

• Meets the requirements of ICC ES AC32 Section 3.1.1 (plastic shrinkage reinforcement).

• Excellent distribution of monofilament fibers throughout concrete

• Excellent finishability of concrete

• Excellent reduction in plastic shrinkage cracking

What are the benefits of MasterFiber M 70 synthetic fibers?

MasterFiber M 70 modifies macro- and micro-cracking mechanisms and reduces plastic settlement. Its monofilament fibers produce concrete with extended service life that needs less maintenance and has enhanced resistance to impacts and surface abrasion.​
