Sika® Fibermesh® FN

MICRO-NYLON MONOFILAMENT FIBER

Sika® Fibermesh® FN is a monofilament nylon micro-fiber for use as secondary reinforcement in concrete.  Manufactured from 100% virgin nylon (polyamides).  Sika® Fibermesh® FN  is designed to control plastic shrinkage and settlement cracking as secondary concrete reinforcement. 

  • Reduces plastic shrinkage cracking
  • Reduces plastic settlement cracking
  • Improves hydration and reduces crazing cracking (hydrophilic fibers)
  • Improves impact, shatter and abrasion resistance
  • UV stability
  • High fiber count
  • Excellent tensile strength
  • High elasticity
  • Reinforces against abrasion
  • Helps reduce cracing from freeze/thaw

Usage

Sika® Fibermesh® FN act mechanically by supporting the aggregate within the concrete with multidimensional fiber network and developing a uniform bleed system.  Sika® Fibermesh® FN can retain approximentally 4-5% of their weight in water, slowing bleed water, aiding in hydration and reducing crazing cracking.  Typical applications include:
  • Slabs on ground
  • Architectural concrete
  • Precast elements
  • Stucco
 

Advantages

  • Reduces plastic shrinkage cracking

  • Improves impact, shatter and abrasion resistance
  • UV stability
  • High fiber count
  • Excellent tensile strength
  • High elasticity
  • Reinforces against abrasion
  • Helps reduce cracing from freeze/thaw

Packaging

Sika® Fibermesh® FN fibers are available in a variety of packaging options in degradable bags.
