Product Description

Perkadox GB-50L Dibenzoyl peroxide

Product Description

 

Perkadox GB-50L 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, Nouryon recommends a maximum storage temperature (Ts max. ) for each organic peroxide product.

Ts Max.:25°C
Note:When stored under these recommended storage conditions, Perkadox GB-50L
will remain within the Nouryon specifications for a period of at least 12 months

 

Perkadox GB-50L 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.
SADT:55°C
Method: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).

 

Perkadox GB-50L Safety and handling
Keep containers tightly closed. Store and handle Perkadox GB- 50L in a dry well-ventilated place away from sources of
heat or ignition and direct sunlight. Never weigh out in the storage room. Avoid contact with reducing agents (e. g.
amines), acids, alkalis and heavy metal compounds (e. g. accelerators, driers and metal soaps). Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of Perkadox GB-50L. This information should be thoroughly reviewed prior to acceptance of this product.

Major decomposition products
Carbon dioxide, benzene, benzoic acid, diphenyl, phenylbenzoate

 

Perkadox GB- 50L is a free-flowing 50% peroxide formulation on a phthalate-free carrier for curing unsaturated polyester resins and (meth)acrylic resins at ambient and elevated temperatures. Provides excellent solubility in standard thermoset curing applications.


Perkadox GB-50L Packaging and transport
The standard packaging is a non-returnable cardboard box for 25 kg net. Both packaging and transport meet the international regulations. For the availability of other packed quantities consult your Nouryon representative. Perkadox GB-50L is classified as Organic peroxide type D, solid; Division 5. 2; UN 3106.

Application

Perkadox GB-50L is a free flowing, fine, granular powder containing 50% dibenzoyl peroxide, with max. 0.5% water.Perkadox GB- 50L is used for the curing of unsaturated polyester and (meth)acrylic resins at ambient and elevated temperature. At temperatures up to 80°C, Perkadox GB- 50L should be used in combination with an aromatic tertiary amine accelerator. Above 80°C the use of an accelerator is not required. Perkadox GB- 50L dissolves clearly in the resin system and is therefore very suitable for the production of cured parts with acrylic resins when a high degree of transparency is required.
