AC1 Cobalt Accelerator (1%)

The curing of unsaturated vinylester and polyester resins at normal ambient temperature requires both an organic peroxide (known as the catalyst, such as MEKP) and an accelerator, typically cobalt salt.

In most unsaturated polyester and vinylester resins, cobalt accelerator has already been added to the resin and does not need to be added at the time of use. However, pre-acceleration of resin systems reduces their shelf-life and therefore some more reactive resins are supplied un-accelerated and require a small amount of accelerator to be added at the time of use, as well as the catalyst, to cure properly.

AC1 is a cobalt accelerator in a concentration of 1% in styrene. AC1 should be added to un-accelerated polyester and vinylester resin systems (such as our VE140 Fuel Resistant Vinylester Resin) as a cure promotor, according to the recommendations of the resin supplier.

Important Information

Veiligheidsinformatie

Always fully mix the accelerator into the resin system before adding the catalyst. Never mix promotors, such as AC1 Cobalt Accelerator, directly with catalysts like MEKP, otherwise a violent reaction can occur. See SDS and TDS for full safety information.

Kopen

AC1 is available to buy online in 250g quantities.

It is typically added at around 4% meaning that a 250g pack is sufficient for 5kg of resin.

Houdbaarheid

AC1 Cobalt Accelerator has a shelf life of 3 months from date of manufacture.
