Product Description

TRIGONOX K-90 Product Description

TRIGONOX K-90 stands for isopropyl hydroperoxide, 90% aromatics solution, initiator for polymerization or copolymerization of styrene, butadiene, acrylonitrile, vinyl acetate, acrylate, and methacrylate. Can also be used for curing unsaturated polyester resin, is a kind of epoxy curing agent, a more commonly used composite material.

Trigonox K-90

Without the addition of an accelerator the polymerization starts only above the activation temperature of 90°C. For the cure at lower temperature Trigonox K-90 must be accelerated by cobalt or vanadium. Together with cobalt accelerators the gel time at room temperature is very long and is therefore particularly suitable for those applications where a long production time is required, for instance in the production of large parts and in filament winding. Sufficiently fast gel and cure times are only obtained above 35°C.

Together with vanadium accelerators Trigonox K- 90 gives a short gel time and a fast cure at room temperature. This can be improved further by adding a special promotor, like pyruvic acid. With such a system it is possible to get a fast cure of UP resins, even at low temperature. Also for resins like vinylester resin, these combinations are very suitable.

Due to the relatively unstable nature of organic peroxides a loss of quality

can be detected over a period of time. To minimize the loss of quality,

AkzoNobel recommends a maximum storage temperature (Ts max.) for

each organic peroxide product.

For Trigonox K-90

Ts max. = 40°C and

Ts min. = -30°C to prevent crystallization

When stored under these recommended storage conditions, Trigonox K-90

will remain within the AkzoNobel specifications for a period of at least 3

months after delivery.

Thermal stability

Organic peroxides are thermally unstable substances, which may undergo

self-accelerating decomposition. The lowest temperature at which self-

accelerating decomposition of a substance in the original packaging may

occur is the Self-Accelerating Decomposition Temperature (SADT). The

SADT is determined on the basis of the Heat Accumulation Storage Test.

For Trigonox K-90

SADT : 70°C

The Heat Accumulation Storage Test is a recognized test method for the determination of the

SADT of organic peroxides (see Recommendations on the Transport of Dangerous Goods,

Manual of Tests and Criteria - United Nations, New York and Geneva).

Major decomposition

Acetophenone, 2-Phenylisopropanol, Methane
