Nouryon Perkadox GB-50L Dibenzoyl peroxide
Categories:	Other Engineering Material
Material Notes:	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. CAS number: 94-36-0 EINECS/ELINCS No.: 202-327-6 Applications: 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.
