Overview
Trigonox HMa is a methyl isobutyl ketone peroxide (MIBKP) formulation for the curing of unsaturated polyester resins, used either on its own or in combination with a cobalt accelerator across a temperature range of 60-150°C. As one of the recommended international brand products in our organic peroxide range, this curing agent is supplied with supply chain resource support for fabricators sourcing a MIBKP-based peroxide for filament winding and sheet production.
Specifications of Trigonox HMa
- Appearance: clear liquid

- Density: 0.99 g/cm³
Viscosity at 20°C is listed on the product’s technical data sheet; fabricators should always confirm the current viscosity value and full specification table against the latest technical data sheet before finalizing a formulation.
Applications
Trigonox HMa can be used in combination with a cobalt accelerator, such as Accelerator NL-49PN, for applications where a long gel time or production time is required at ambient temperature along with a fast cure at higher temperatures, for example 60-100°C. Typical application areas include filament winding and the production of flat and corrugated sheets.
This curing agent also shows high reactivity at elevated temperatures without the addition of a cobalt accelerator, which is demonstrated by its low activation temperature. It can therefore be used in the temperature range of approximately 80-150°C for the production of flat and corrugated sheets where discoloration from a cobalt accelerator is not acceptable, as well as a kicker for pultrusion applications in combination with a low reactive peroxide such as Trigonox 29-IN50 or Trigonox C. The low reactive peroxide must be included in the formulation to achieve a complete cure.
Why Cure Profile and Cobalt-Free Options Matter
Fabricators producing flat or corrugated sheet products often need to balance a long enough gel time for handling and lay-up with a fast enough cure at elevated temperature to keep production cycles efficient. A peroxide that performs well both with and without a cobalt accelerator gives formulators flexibility to adjust the cure profile to their process, while also offering a cobalt-free curing route for applications where accelerator-related discoloration would affect the finished sheet’s appearance.
In pultrusion, using this peroxide as a kicker alongside a low reactive peroxide is one way formulators manage cure speed through the die, since the low reactive component and the kicker peroxide play different roles across the cure profile. Fabricators should always confirm current dosage ratios and cure schedule recommendations against the latest technical data sheet for their specific resin system and process line.
What to Consider When Sourcing Trigonox HMa
When sourcing an organic peroxide curing agent for unsaturated polyester resin, fabricators typically evaluate active oxygen content, compatibility with cobalt accelerators, and cure behavior across their process temperature range. Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new peroxide for a filament winding, sheet, or pultrusion line.
Because organic peroxides are reactive and hazardous materials, buyers should confirm current handling, storage, and transport classification requirements against the latest technical data sheet and safety data sheet before introducing a new peroxide into their production process, rather than assuming requirements are identical to a different peroxide grade already in use.
