Storage

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 (T_s max.) for

each organic peroxide product.

For Trigonox 44B

T_s max. = 25°C

T_s min. = -10°C to prevent crystallization

When stored under the recommended storage conditions, Trigonox 44B

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 44B

SADT : 60°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

Carbon dioxide, acetyl acetone, mixture of aliphatic acids, water
