PRO-SET High Temp Infusion Hardener HTP-280
Description
PRO‑SET® HTP‑280 High‑Temp Infusion Epoxy Hardener ONLY
PRO‑SET® HTP‑280 is a high‑temperature epoxy hardener designed for use with PRO‑SET® HTP‑180 High‑Temp Infusion Epoxy resin. Together, this system is engineered for advanced composite manufacturing using resin infusion and VARTM processes where elevated temperature performance, long working time, and laminate quality are critical.
When combined with HTP‑180 epoxy and properly post‑cured, the system can achieve a glass transition temperature (Tg) up to 300°F (149°C). HTP‑280 provides controlled reaction speed, low mixed viscosity, and extended pot life to support complete wet‑out and reliable flow through dense reinforcements and complex laminate schedules.
Key Features
- Formulated specifically for use with PRO‑SET® HTP‑180 epoxy resin
- Designed for resin infusion and VARTM processing
- Supports high post‑cure temperature performance
- Low viscosity for excellent flow and fiber wet‑out
- Long working time for large or complex infusions
- Produces strong laminates with excellent surface finish
Handling Highlights (at 72°F / 22°C)
- Mixed viscosity approximately 600 cP (with HTP‑180)
- Hardener viscosity approximately 35 cP
- Pot life options approximately 120–180 minutes depending on mix mass and conditions
Cure Notes
- Requires elevated temperature cure for full high‑temperature properties
- Room‑temperature initial cure followed by staged post‑cure recommended
- Not intended for open‑mold wet layup applications
Typical Applications
- High‑temperature composite tooling
- Infused carbon fiber structural parts
- Aerospace and motorsport components
- High‑performance sandwich structures
