Overview

Trigonox 93 is a liquid organic peroxide formulation based on tert-butylperoxybenzoate and acetylacetone, developed for the cure of unsaturated polyester resins in combination with a cobalt accelerator, such as an accelerator with 10% cobalt content, in the temperature range of 60°C and higher. As one of the recommended international brand products in our organic peroxide range, Trigonox 93 is supplied with supply chain resource support for formulators sourcing curing systems for polyester and vinylester resin applications.

Applications of Trigonox 93 Across Cure Systems
This peroxide ester plus a cobalt accelerator can effectively be used as a match for Trigonox 21S in applications where Trigonox 21S is restricted by its official transport and storage temperature of 20°C maximum. Application areas for this cure system include artificial marble, polymer concrete, filament winding, and air-drying lacquers.
Why This Grade Suits Ambient-Temperature Vinylester Cure
The combination of this product plus a cobalt accelerator, and possibly an amine accelerator such as N,N-Dimethylaniline, is also suitable for the ambient-temperature cure of vinylester resins. In these resins, it gives a considerably faster cure than the commonly applied peroxides Butanox LPT-IN and Trigonox 239, which is a relevant consideration for formulators optimizing cure speed in ambient-cure vinylester systems.
Why Sourcing Consistency Matters for Buyers
Because assay and color directly affect cure performance and resin clarity, formulators should confirm current specifications for this peroxide ester against the latest technical data sheet before scheduling a production run. A supplier that consistently delivers this material within its stated assay and color specifications reduces the need to re-qualify a cure recipe with every new batch.
This is particularly relevant for artificial marble, polymer concrete, and filament winding producers, where cure speed and resin clarity are directly tied to peroxide purity and dosing consistency alongside the correct cobalt accelerator loading. Buyers should confirm current batch documentation against the latest technical data sheet before finalizing a production schedule.
What to Consider When Sourcing Trigonox 93
Buyers evaluating Trigonox 93 for the first time should confirm which of the primary use cases applies to their process, elevated-temperature cure of unsaturated polyester resin above 60°C, or ambient-temperature cure of vinylester resin with a cobalt and amine accelerator combination, since accelerator selection and dosing differ across these applications even though the same peroxide is used. 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 material 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, dry, 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 93 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 assay and performance characteristics described above.
