R3501 3:1 Infusion Epoxy
Description
Description
R3501 Epoxy Resin
R3501 is a high-quality, low-viscosity epoxy resin formulated for vacuum infusion and other closed-mold processes. It wets out reinforcement quickly and flows uniformly to help produce void-free laminates with consistent fiber volume.
Required hardener:H5000 Hardener(sold separately). Use only with the matched H5000 curing agent to achieve the specified cure and properties.
Key Features
- Low viscosity for infusion: Promotes fast wet-out and even resin distribution.
- Clean processing: Designed to minimize air entrapment and dry spots in complex layups.
- Consistent results: System-matched with H5000 for predictable cure and strong, durable laminates.
- Shop friendly: Suitable for hand layup, VARTM/vacuum infusion, and light RTM workflows.
- Made in the USA (per supplier information).
Typical Applications
- Composite panels, marine parts, automotive and general fabrication
- Molds, plugs, and repairs where uniform wet-out and flow are critical
- Vacuum infusion (VARTM) and other closed-mold processes
Mixing & Use
- Mix R3501 with H5000 Hardener at the ratio specified on the system TDS (by volume or weight).
- Measure accurately and blend thoroughly, scraping sides and bottom of the cup to ensure a uniform mix.
- Control exotherm: pour into a shallow tray or apply in thin sections; larger masses gel faster.
- If surface amine blush is present after cure, wash with clean water and a light abrasive pad before sanding or overcoating.
- For maximum properties, follow any recommended post-cure schedule on the TDS.
Safety & Storage
- Wear chemical-resistant gloves and eye protection; ensure adequate ventilation.
- Avoid skin contact; wash with soap and water after handling.
- Store sealed in a cool, dry location. Consult the SDS and TDS for full safety and handling guidance.
