RDH-9386 RTM Room Temperature Hardener
Description
RDH-9386 RTM Room Temperature Hardener
RDH-9386 is a versatile room temperature epoxy hardener designed for RTM and vacuum-infused composite systems. It provides a balanced pot life with dependable cure, making it ideal for production parts and tooling where consistent handling and strong mechanical performance are required. RDH-9386 offers excellent wet-out on carbon fiber, fiberglass, and Kevlar® reinforcements when used with compatible Premium Resin Tech RDR-series resins.
Key Features
- Room temperature cure: reliable cure schedule at typical shop temperatures for RTM and infusion processes.
- Balanced working time: provides ample open time for wetting reinforcements and filling complex molds.
- Excellent wetting & adhesion: formulated for strong bonds to carbon, fiberglass, and aramid fabrics.
- High mechanical performance: supports high tensile, flexural, and compressive strength in compatible resin systems.
- Production-friendly: consistent behavior batch-to-batch for repeatable RTM and closed-mold manufacturing.
Compatible Resins
Use RDH-9386 with the following Premium Resin Tech epoxy resins:
- RDR-3121 High Impact / High Temp Vacuum Infusion Epoxy
RDR-3212 High Impact Room / High Temperature Laminating Resin
- RDR-3410 Room Temperature Epoxy Laminating Resin
Available Package Sizes
- 2.75 lbs – approx. 1/2 Gallon
- 15 lbs – approx. 1.25 Gallons
- 165 lbs – approx. 18.15 Gallons (drum; may have additional lead time)
Sold by weight: all sizes are sold in pounds for accurate metering and consistent mix ratios.
Mixing & Use
- Mix only with the specified RDR-series resins at the recommended ratio (see product TDS).
- Condition materials to shop temperature before mixing for predictable viscosity and cure.
- Measure by weight, then mix thoroughly, scraping the sides and bottom of the container.
- Use in RTM, vacuum-assisted resin transfer, or other closed-mold processes where controlled flow and cure are needed.
- Follow the Technical Data Sheet (TDS) and Safety Data Sheet (SDS) for full cure schedules, post-cure options, and safety guidelines.
Applications
- RTM and closed-mold production of structural composite parts.
- Automotive, industrial, and aerospace components using carbon, fiberglass, or Kevlar® reinforcements.
- Composite tooling and fixtures where room-temperature cure and strong mechanical properties are required.
RDH-9386 RTM Room Temperature Hardener is part of the Premium Resin Tech epoxy family, engineered for consistent, high-quality performance in demanding composite manufacturing environments.
