Overview
Trigonox K-90 is an organic peroxide initiator (90% active ingredient in an aromatic solvent mixture) used for the (co)polymerization of (meth)acrylates. As one of the recommended international brand products in our organic peroxide range, Trigonox K-90 is supplied with supply chain resource support for formulators sourcing an initiator for polymer production, thermoset composites, and acrylics production.

Applications
Trigonox K-90 can be used for the market segments: polymer production, thermoset composites and acrylics production with their different applications and functions. It is formulated specifically for the (co)polymerization of (meth)acrylates, which is relevant for formulators running acrylic-based polymerization processes that require a liquid, aromatic-solvent-carried initiator.
Because this initiator is supplied at 87.0–90.0% assay in an aromatic solvent mixture rather than as a neat peroxide, formulators should confirm dosage and compatibility with their specific monomer system against the latest technical data sheet before finalizing a formulation.
Why Active Oxygen and Assay Matter for Trigonox K-90
Active oxygen content and assay are two of the primary quality markers formulators check when qualifying an organic peroxide initiator for (meth)acrylate polymerization, since both values directly indicate how much active initiator is available per unit of product. With an active oxygen content of 9.14–9.46% and an assay of 87.0–90.0%, Trigonox K-90 is positioned to deliver consistent, repeatable initiation performance across production batches.
Because Trigonox K-90 is also characterized by a defined viscosity (10.9 mPa.s at 20°C) and density (1.05 g/cm³ at 20°C), formulators can use these handling properties to plan metering and dosing equipment for continuous or batch acrylate polymerization lines, rather than relying on assumptions carried over from other initiator grades.
What to Consider When Sourcing Trigonox K-90
When sourcing an organic peroxide initiator for (meth)acrylate (co)polymerization, formulators typically evaluate active oxygen content, assay, appearance, and color specification, alongside consistent batch-to-batch quality. Working with a supplier that can provide current documentation and responsive technical support can help reduce qualification time when approving a new initiator for a production line.
Because this is a peroxide product supplied in an aromatic solvent carrier, dosage and process compatibility should always be confirmed against the latest technical data sheet before finalizing a formulation, and small-batch trials are recommended prior to full-scale production runs.
General Handling and Storage Guidance
As an organic peroxide, this product should be kept in its original, tightly sealed container, stored in a cool, dry location away from direct sunlight and other heat sources, and handled according to standard organic peroxide safety practices.
Storage temperature limits, shelf life, and handling precautions vary by batch and packaging format, so formulators should always confirm current storage conditions and safety guidance against the latest technical data sheet and SDS for the specific batch of Trigonox K-90 they are working with.
