Overview
Trigonox® K-80 is a high-purity cumyl hydroperoxide (CHP) initiator supplied as an 80.0-85.0% active clear liquid in aromatic solvent. With an active oxygen content of 8.40-8.94% and low viscosity (10.4 mPa.s at 20°C), it functions as a versatile radical initiator for polymer production, thermoset composite curing, and acrylic polymerization. Its higher decomposition temperature compared to ambient-cure peroxides such as MEKP or BPO makes it suitable for processes that require initiation or curing at elevated temperatures.
Key Benefits
- High active oxygen content (8.40-8.94%) supports efficient initiation at practical dosage levels
- Clear, low-color liquid (≤ 200 Pt-Co) minimizes discoloration in finished polymers and composites
- Low viscosity (10.4 mPa.s at 20°C) for easy metering and blending into resin or monomer systems
- Suited to elevated-temperature curing and polymerization processes where ambient-cure peroxides are not appropriate
- Consistent quality supported by technical documentation for every shipment

Applications
Trigonox® K-80 is used across three main market segments:
- Polymer production – as a radical initiator in polymerization processes, particularly where a higher decomposition temperature is needed to control reaction rate.
- Thermoset composites – as a curing initiator for unsaturated polyester and vinyl ester resin systems processed at elevated temperature, such as pultrusion, filament winding, and hot-press molding.
- Acrylics production – as an initiator for (co)polymerization of acrylate and methacrylate monomers.
For process-specific dosage and compatibility guidance, our technical team can help match Trigonox® K-80 to your resin system and cure profile.
Selection Guide: Trigonox® K-80 vs. Other Peroxide Initiators
Compared to ambient-cure peroxides such as MEKP or BPO, Trigonox® K-80 is designed for processes that run at higher temperatures, where a higher decomposition temperature is needed to control the reaction. If your process runs at ambient to moderate temperature, an MEKP or BPO-based system may be more suitable; for hot-press molding, pultrusion, or elevated-temperature polymerization, Trigonox® K-80 is typically the better fit. Our technical team can help confirm the right grade based on your process temperature, resin type, and target cure or reaction time.

FAQ
What is Trigonox® K-80 used for?
It is used as a radical initiator in polymer production, as a curing agent for thermoset composites (unsaturated polyester and vinyl ester resins) at elevated temperature, and as an initiator for acrylate/methacrylate polymerization.
How does Trigonox® K-80 differ from MEKP or BPO?
Trigonox® K-80 has a higher decomposition temperature, making it more suitable for elevated-temperature curing and polymerization processes, while MEKP and BPO are typically used for ambient-temperature curing.
Is COA/MSDS available for each batch?
Yes, Certificate of Analysis and Safety Data Sheet documentation are available on request for each shipment.
What is the MOQ and lead time?
MOQ and lead time depend on packaging format and destination. Contact our team with your target volume and delivery location for a specific quote.
How should Trigonox® K-80 be stored?
As with other organic peroxides, store in a cool, well-ventilated area away from direct sunlight and heat sources, and away from incompatible materials. Refer to the SDS for complete storage and handling guidance.
Can you help me select the right grade for my process?
Yes – share your resin/monomer system, process temperature, and target cure or reaction time, and our technical team can recommend the appropriate grade and dosage.
