Product details

Product TypeCobalt Octoate Accelerator / Promoter
FunctionCuring accelerator / promoter for compatible unsaturated polyester resin systems
Typically Used WithPeroxide-initiated cure systems such as MEKP
CategoryHardeners

Cobalt Octoate is Samrat Poly Resins' cobalt-based accelerator / promoter, positioned for compatible unsaturated polyester resin curing systems. It is commonly associated with peroxide-initiated cure systems such as MEKP, where its role is to accelerate and promote the curing reaction. Cobalt Octoate is not itself a polyester resin, a standalone hardener or a finished composite material — it is a separate accelerator component used alongside a selected base resin and peroxide catalyst. It is catalogued under Hardeners for browsing convenience alongside the other curing-system components; review the actual resin system, peroxide catalyst and current product data before finalising a curing formulation.

Cobalt Octoate is a separate accelerator / promoter component, typically used alongside a peroxide catalyst such as MEKP Hardener in a compatible unsaturated polyester resin system. It does not replace the base resin, the catalyst or any reinforcement material — confirm the actual resin grade and current product data before selecting a complete curing system.

Key features

  • Cobalt-based accelerator / promoter for compatible unsaturated polyester resin systems
  • Commonly used alongside peroxide-initiated cure systems such as MEKP
  • Supplied as a separate accelerator component, not a standalone hardener or resin
  • Catalogued under Hardeners for browsing convenience alongside other curing-system components
  • Chemically distinct from, and not a substitute for, the peroxide catalyst it is paired with
  • Suited to workshops already running an MEKP-initiated, room-temperature cure process

Applications

  • Unsaturated polyester resin curing systems where a cobalt-based accelerator is specified
  • FRP fabrication and moulding processes using MEKP-initiated cure
  • General composite manufacturing where a separate accelerator / promoter component is required

Frequently asked questions

Cobalt Octoate is a cobalt-based accelerator / promoter used with compatible unsaturated polyester resin curing systems, commonly alongside a peroxide catalyst such as MEKP.

No. Cobalt Octoate is a separate accelerator / promoter component. MEKP Hardener is the peroxide catalyst / initiator typically used alongside it — the two perform different roles within a curing system.

No. It is an accelerator / promoter component only, used alongside a separately selected base resin and catalyst — not a structural resin and not a complete curing agent on its own.

Please share the base resin system, intended application, expected quantity and delivery location so the team can understand the requirement before preparing a quote.

Request the current Safety Data Sheet (SDS) at the time of enquiry for storage, handling and PPE guidance.

Share your expected quantity when requesting a quote — packaging and bulk-order options are confirmed at that stage.
