COMACC Sodium

Comar has developed a new Sodium Accelerator, that replaces the traditional Potassium Accelerator, which is used in the curing of Unsaturated Polyester Resins. The advantage of Sodium over Potassium is that its use will lead to lighter coloured cured resins, while providing all the functions of Potassium in conjunction with Cobalt.

 


 

COMACC Copper

Copper is used to retard the cure of unsaturated polyester systems and is known to lower the peak of the exotherm in certain formulations.

 


 

COMACC Co-21/N

This product is a cobalt feeder, and is used in conjunction with standard Cobalt Accelerators. Its function is to maintain the activity of the cobalt accelerator of a period of time.
