More about this item

WEST SYSTEM 879-18 Fiberglass & Repair

This professional-grade release fabric is an essential component for vacuum bagging operations and advanced hand lay-up applications. The 60" x 9" size provides convenient coverage for smaller projects and repairs, while the tough nylon construction with release agent treatment ensures clean separation and optimal surface preparation.

Vacuum Bagging Applications:

In vacuum bagging operations, this release fabric serves as a critical barrier between the absorber, breather material, vacuum bag, and your laminate. It allows excess epoxy to bleed through while preventing the breather and bag from bonding to your work. After cure, the fabric peels away cleanly along with any excess resin, leaving behind a perfectly textured surface that's ready for secondary bonding or finishing without additional surface preparation.

Enhanced Hand Lay-Up Performance:

For hand lay-up applications, release fabric allows you to apply significantly more squeegee pressure to achieve better fiber wet-out and consolidation without damaging the laminate surface. It also protects your lay-up from contamination during the cure process, ensuring consistent, professional results.

Tough Nylon Construction:

Made from finely woven nylon fabric treated with a release agent, this material is engineered for reliable performance and clean release. The tough construction withstands the rigors of composite fabrication while the release treatment ensures it peels away easily without tearing or leaving residue.

Key Features:

  • Clean Release: Peels easily from cured laminates without tearing
  • Optimal Surface Texture: Leaves a smooth, textured surface ideal for bonding or finishing
  • Tough Construction: Finely woven nylon withstands fabrication demands
  • Release Agent Treated: Ensures reliable separation from epoxy
  • Versatile Use: Works in both vacuum bagging and hand lay-up applications
  • Convenient Size: 60" x 9" perfect for smaller projects and repairs

Common Applications:

  • Vacuum bagging composite laminates
  • Hand lay-up fiberglass work requiring high consolidation
  • Preparing surfaces for secondary bonding
  • Protecting laminates during cure
  • Creating textured surfaces for paint or gelcoat adhesion
  • Smaller repairs and patch work

Important Temperature Limitation:

This release fabric is not recommended for post-cure temperatures over 120°F. For applications requiring higher temperature post-curing, use alternative release materials rated for elevated temperatures.

Specifications:

  • Size: 60" x 9"
  • Material: Finely woven nylon with release agent
  • Maximum Post-Cure Temperature: 120°F

Whether you're performing vacuum bagging or precision hand lay-up work, this release fabric delivers the clean release and surface quality that professional composite fabrication demands.
