- Product Applications
- Perkadox® GB-45C is a free flowing, almost dust-free, granular powder containing up to 45% dibenzoyl peroxide.
- Perkadox® GB-45C 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-45C should be used in combination with an aromatic tertiary amine accelerator. Above 80°C the use of an accelerator is not required.
- Perkadox® GB-45C 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.

The standard packaging is a non-returnable cardboard box for 25 kg net.
Storage & Handling
- Shelf Life
- 12 months
- Storage and Shelf Life Information
- 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.
- Maximum storage temperature is 25°C
- When stored under these recommended storage conditions, Perkadox® GB-45C will remain within the Nouryon specifications for a period of at least 12 months after delivery.
