Perovion AAP-TBPB L27 is an organic peroxide blend combining acetylacetone peroxide (AAP) and tert-butyl peroxybenzoate (TBPB), formulated for curing unsaturated polyester and vinyl ester resins under ambient and elevated temperature conditions. When used in conjunction with a metal accelerator, this AAP TBPB peroxide blend initiates the crosslinking reaction in thermoset resin systems, supporting consistent cure across a range of composite manufacturing processes.
Key Features
- Organic peroxide blend combining acetylacetone peroxide (AAP) and tert-butyl peroxybenzoate (TBPB) for polyester and vinyl ester curing.
- Dual-peroxide formulation provides initiation activity across ambient and elevated processing temperatures.
- Suitable for curing in conjunction with a cobalt or other metal accelerator system.
- Applicable in GRP laminating, composite panel fabrication, and general thermoset processing.
- Intended for industrial and professional use only.
Typical Applications
Perovion AAP-TBPB L27 can be applied in curing unsaturated polyester and vinyl ester resin systems, including composite laminates, GRP fabrication, and thermoset processing applications where a dual-temperature initiation profile is required. The combination of AAP and TBPB peroxide chemistry makes this blend suitable for both ambient-initiated processes and systems requiring additional elevated-temperature through-cure.
