PRO-SET High Temp Laminating Epoxy Hardeners
Description
PRO‑SET® High‑Temp Laminating Epoxy Hardener (HTP‑286 Slow / HTP‑284 Fast)
PRO‑SET® HTP‑286 (Slow) and HTP‑284 (Fast) are high‑temperature laminating epoxy hardeners formulated for advanced composite parts and tooling applications requiring elevated thermal and mechanical performance. These hardeners are designed for use with PRO‑SET® HTP‑182 High‑Temp Laminating Epoxy Resin to create a high‑performance laminating epoxy system.
Two cure speeds are available so you can match working time and gel time to your project size and shop conditions. Both versions provide consistent fabric wet‑out, reliable cure, and excellent laminate quality when properly mixed and post‑cured with HTP‑182 resin.
With proper elevated‑temperature post cure, the HTP‑182 system can achieve a glass transition temperature (Tg) up to 300°F (149°C), making it suitable for high‑temperature composite tooling and structural components.
This product includes the hardener only. Must be used with PRO‑SET® HTP‑182 resin at the specified mix ratio to achieve full performance properties.
Key Features
- High‑temperature laminating epoxy hardener
- Designed specifically for HTP‑182 laminating epoxy resin
- Available in Fast and Slow cure speeds
- Supports high‑strength, high‑Tg composite laminates
- Excellent laminate quality and surface finish
- Suitable for composite parts and tooling
Speed Selection Guide
- HTP‑284 Fast: Shorter gel time and faster turnaround for smaller parts and quicker production cycles
- HTP‑286 Slow: Longer working time for large layups and complex tooling laminates
Processing Notes
- For laminating, vacuum bagging, and composite tooling processes
- Working and gel times vary by hardener speed and temperature
- Elevated temperature cure required for full high‑temperature properties

Laminating Hardener Comparison (Verified)
| Speed | Typical Working/Open Time* | Initial Gel / “Green” | Best For | Notes |
|---|---|---|---|---|
| Fast (HTP-284) | ~1-2 hr | ~4-6 hr | Small parts, cool shops, quick turn | Minimize batch size to control exotherm. |
| Slow (HTP-286) | ~4–5 hr | ~8-10 hr | General laminating, day-to-day work | Balanced pot life and cure speed. |
*Times are approximate; actual values vary with temperature, batch size, and layup. †Published at ~29 °C / 85 F; at ~25 °C / 77 °F expect slightly longer.
