Fiberglass Filler: Heavy-Duty Repair Performance with SYNEW’s SY016
Fiberglass filler is a specialist repair material designed for heavy-duty work on glass fiber reinforced plastic (GRP), automotive bumpers, and welded metal substrates. Unlike light putties intended for small chips or cosmetic touch-ups, a high-quality fiberglass filler offers strength, excellent adhesion, and dimensional stability — all essential when repairing large cracks, deep scratches, holes, or structural defects. For bodyshops, fleet owners, and distributors seeking a cost-effective yet professional-grade solution, SYNEW’s SY016 Fiber Glass Putty delivers the performance required for demanding repair jobs while supporting one-stop procurement and dependable partnership.
What makes a good fiberglass filler?
A reliable fiberglass filler must combine several properties:
- High filling power for large voids and deep damage.
- Strong bonding to GRP, plastics, and metal substrates.
- Low shrinkage during cure to avoid sinkage and post-sand irregularities.
- Good sandability to create a stable, smooth base for primer and paint.
- Compatibility with common polyester, epoxy, and refinish systems used in collision repair.
SY016 Fiber Glass Putty — engineered for heavy duty repairs
The SY016 Fiber Glass Putty (also referred to as SY016fiberglass filler) is a heavy-duty polyester putty specially formulated for repairing large cracks, deep scratches, holes and other major defects on glass fiber reinforced plastic parts, automobile bumpers, and welded metal substrates. Engineered for superior filling and anti-shrink performance, SY016 provides a stable, sandable base that prevents post-spray weld unevenness. Its balanced formulation ensures easy application, strong mechanical properties after cure, and reliable long-term stability under paint.
