Product Application of Perkadox PF-DBM25 CAS#1931-62-0
As a versatile organic-peroxide curing initiator, Perkadox PF-DBM25 is well-suited for room-temperature cross-linking of methyl-methacrylate-based resin and acrylic solid-surface materials, with little risk of yellow-ing finished-goods. It works together with dedicated accelerators to speed-up the hardening procedure of composite thermoset substances. Besides its curing function, this peroxide serves as an efficient free-radical source in polymer synthesis and fine-chemical preparation. It also gets adopted in optoelectronic-related material processing and acts as a chemical intermediate for multiple industrial-grade organic reactions. Operators should strictly follow safe-handling guidelines during every-day industrial usage.
