Description
The Chem-Set 829 Infusion Epoxy Series is a two-component, ultra-low viscosity epoxy resin system formulated for vacuum-assisted resin transfer molding (VARTM) and resin infusion applications. Engineered for professional composite manufacturing, it provides exceptional wet-out, high mechanical strength, and outstanding thermal stability—ensuring void-free, high-performance laminates.
Key Features & Benefits
- Three Cure Speeds: 829-FS (Fast), 829 (Medium), 829-SS (Slow)
- Low mixed viscosity (~291 cP @ 77°F) for rapid fiber wet-out
- High mechanical and thermal performance (Tg up to 232°F)
- Clear, void-free finishes for superior aesthetics
- Room-temp cure with optional post-cure
- Non-flammable and OSHA-compliant
- Available in drum kits for industrial use
Applications
- Marine composites (hulls, decks, panels)
- Aerospace and automotive laminates
- Wind turbine blades and nacelles
- Industrial tooling and carbon fiber fabrication
