Benzoyl Peroxides (see structure)
Luperox® ANS55 (Benzoyl peroxide)	Mainly used to cure at low and medium temperatures up to 80°C. Used with tertiary aromatic amines at ambient temperatures. The peroxide/amine system gives quick gel and cure times. Used for polyester repair putties and mine bolts. Good solubility in polyesters. May also be used in hot press molding for quick cycles at 100°C - 120°C. Other colors and concentrations on request.	Paste/ Plasticizer phthalate	3.63-3.83	60	Cold molding, Filament winding, Hot molding, Concrete & marble, Putties, and Acrylic Adhesives
Luperox® ACP35 (Benzoyl peroxide)	Used for the production of acrylic and polyester concrete, as well as standard applications, where the inorganic filler does not disturb, e.g. mine bolts.	Powder/ Inorganic filler	2.31-2.44	60	Concrete, marble and solid polyester
Luperox® A98	Anhydrous BPO.	Granular Dry Solid	>6.47	60	Silicone Adhesives where water is detrimental
Luperox® A75	75% BPO with water.	Granular Wet Solid	4.82-5.08	60	UPR composites applications
Luperox® AFR40	40% BPO in phthalate.	Pourable Paste	2.64-2.77	60	UPR composites applications
Luperox® ATC50	50% Anhydrous BPO in tricresyl phosphate	Paste	3.30-3.44	60	UPR composites applications and Adhesives
Luperox® APF55	55% Anhydrous BPO (non-phthalate proprietary diluent)	Paste	3.63-3.83	60	UPR composites applications and Adhesives

* Temperature at which reaction starts in the system composed only by resin and peroxide (no accelerator)
