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.
How much cobalt? Dosages printed on our resin data sheets
Each grade below prints its own catalyst and accelerator dosage and the gel time on its technical data sheet. Use the sheet for the grade you buy rather than a general range. Workshop temperature and batch size change the working time, so confirm a new grade on a small trial batch before production.

Cobalt octoate is the accelerator; MEKP Hardener is the catalyst. Add each to the resin separately; never mix them directly with each other. For gel-time problems, read troubleshooting polyester cure speed.
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
