Overview
Trigonox 279 is a peroxide formulation based on acetylacetone peroxide and tert-butyl peroxybenzoate, specially developed for the cure of unsaturated polyester resins at elevated temperatures in combination with a cobalt accelerator (e.g. Accelerator NL-49P, 1% cobalt). As one of the recommended international brand products in our organic peroxide range, Trigonox 279 is supplied with supply chain resource support for formulators sourcing a fast-curing peroxide blend for elevated-temperature processing.

Applications of Trigonox 279 in Elevated-Temperature Resin Curing
The cure system formed by Trigonox 279 plus a cobalt accelerator can be used for application areas such as continuous laminating, resin transfer moulding (RTM), filament winding, and centrifugal casting. This combination is intended to deliver rapid, efficient crosslinking of unsaturated polyester resins at elevated processing temperatures.
Why the Dual-Peroxide Blend Matters
Because Trigonox 279 combines acetylacetone peroxide with tert-butyl peroxybenzoate, formulators get a cure profile shaped by two distinct decomposition behaviors rather than a single peroxide type. This blend approach is one reason the product is positioned for higher-temperature, higher-throughput processes such as continuous laminating and filament winding, where rapid crosslinking supports faster cycle times.
Why Sourcing Consistency Matters for Buyers
Because total active oxygen content and color specifications directly affect cure behavior and finished-part appearance, formulators should confirm current specifications for this peroxide blend against the latest technical data sheet before scheduling a production run. A supplier that consistently delivers this peroxide blend within its stated active oxygen and color specifications reduces the need to re-qualify a curing recipe with every new batch.
This is particularly relevant for continuous laminating, RTM, filament winding, and centrifugal casting operations, where cure speed and consistency at elevated temperature are directly tied to peroxide purity and cobalt accelerator dosing. Buyers should confirm current batch documentation against the latest technical data sheet before finalizing a production schedule.
What to Consider When Sourcing Trigonox 279
Buyers evaluating Trigonox 279 for the first time should confirm that its total active oxygen (4.3-4.7%) and color specifications (100 Pt-Co / APHA max.) match their process requirements, and should review which cobalt accelerator and dosage level their process uses alongside this peroxide blend. Requesting the current certificate of analysis alongside the safety data sheet is a practical way to confirm that a given batch matches the specifications listed above.
Packaging, storage temperature requirements, and transport classification should also be confirmed directly with the supplier, since organic peroxides are subject to specific handling and shipping regulations. Buyers sourcing this peroxide blend for time-sensitive production schedules should discuss lead time and temperature-controlled logistics requirements before finalizing an order.
General Handling and Storage Guidance
As with other organic peroxides, this product should be stored in accordance with the supplier’s safety data sheet, typically in a cool, temperature-controlled, well-ventilated area away from direct sunlight, incompatible materials, and sources of heat or ignition. Personnel handling this material should follow the personal protective equipment and handling procedures specified in the SDS, since organic peroxides can decompose exothermically under certain storage or contamination conditions.
Buyers should request and review the current safety data sheet for Trigonox 279 prior to receipt, and confirm that on-site storage conditions, including temperature control, are compatible with the product’s recommended storage requirements. Proper inventory rotation and adherence to the stated shelf life help maintain the active oxygen and performance characteristics described above.
