How It Works
As an organic peroxide, Acetyl acetone peroxide decomposes by homolytic cleavage when heated near 55°C, generating free radicals. These radicals initiate the polymerization or crosslinking of unsaturated monomers (such as styrene, acrylates, vinyls and unsaturated polyester resins), making it a core radical initiator for thermoset and polymer manufacturing.
Primary Applications
Perodox 44B is applied across FRP, Hand Lay-Up, Spray-Up. Typical market segments include Thermoset Composites.
