H5000-01 3:1 Infusion Hardener

H5000 Hardener (for R3501 Epoxy Resin)

H5000 Hardener is the designated curing agent for the R3501 Epoxy Resin(resin sold separately). Together, the system provides dependable room-temperature cure with the option for warm post-cure, delivering strong, durable bonds for laminating, bonding, coating, and general composite repair work.

Key Benefits

• System-matched: Formulated specifically to cure R3501 for predictable results and consistent quality.
• High adhesion & durability: Tough bonds and excellent mechanical strength after full cure.
• Good handling: Efficient wet-out and smooth film formation for hand layup or vacuum-assisted processes.
• Clean finish: Suitable for coatings and laminates that require a professional appearance.
• Versatile: Effective on composites, wood, and properly prepared metals and foams.

Typical Applications

• Composite laminating (hand layup, vacuum bag, general shop builds)
• Structural bonding, fillets, and secondary bonding
• Coating and sealing of patterns, plugs, and fixtures
• Field repairs and maintenance of composite parts

Mixing & Use

• Use only with R3501 Epoxy Resin (sold separately).
• Follow the mix ratio (by volume or weight) specified on the R3501/H5000 system TDS.
• Measure accurately and mix thoroughly, scraping the sides and bottom of the cup.
• Apply in thin films or small batches to control exotherm; larger masses will gel faster.
• If amine blush appears, wash with clean water and a light abrasive pad before sanding or recoating.

Safety

• Wear chemical-resistant gloves and eye protection; ensure adequate ventilation.
• Avoid skin contact; wash with soap and water after handling.
• Consult the product SDS for full precautions and first-aid information.

Note: Pot life, gel time, recoat windows, and final properties depend on temperature, batch size, and the specific application. For exact parameters and cure schedules, refer to the H5000/R3501 Technical Data Sheet.
