1/8" Chopped Strand Fiberglass Quart

1/8" Chopped Strand Fiberglass (Quart) is a high-quality reinforcing filler made from precision-cut 1/8-inch E-glass fibers designed to significantly increase the strength and durability of resin-based composites. When mixed into epoxy, polyester, or vinyl ester resins, these chopped fiberglass strands create a reinforced compound that offers greater tensile strength, improved impact resistance, and enhanced crack resistance compared to resin alone.

The short fiber length disperses evenly throughout the resin, producing a strong, workable mixture that is ideal for structural bonding, gap filling, fillet creation, corner reinforcement, and rebuilding damaged fiberglass components. Unlike longer fiberglass fibers, 1/8-inch chopped strands are easier to mix and spread while still providing excellent reinforcement for high-strength applications.

Perfect for marine, automotive, industrial, aerospace, and general composite fabrication, chopped strand fiberglass is commonly used to reinforce laminates, repair fiberglass boats, strengthen transoms, build fillets, reinforce molded parts, and improve the mechanical properties of custom epoxy putties.

Packaged in a convenient quart-sized container, this material is easy to store, measure, and dispense for projects ranging from small repairs to large composite fabrication jobs.

Note: 1/8" Chopped Strand Fiberglass is a reinforcing additive and should be mixed thoroughly with epoxy, polyester, or vinyl ester resin before application. For maximum strength, combine with an appropriate resin system and follow the manufacturer's recommended mixing ratios. Use proper personal protective equipment when handling dry fiberglass fibers.
