CAS Number: 136-52-7
Physical form: liquid
Accelerator? 553SN is a cobalt accelerator for curing unsaturated polyester resins.
appliance
Accelerator? 553SN is a metal complex solution based in part on cobalt salts in organic solvents. Accelerator? 553SN has a faster cure rate and comparable gelling time compared to commonly used cobalt accelerators. Therefore, Accelerator? 553SN is well suited for end products that require faster release times. Applications such as gelcoat, RTM, polymer concrete production. Accelerator? 553SN can be successfully used for the production of cobalt pre-promoted unsaturated polyester resins. The use of Accelerator? 553SN will significantly reduce the drift in setting time observed with standard cobalt. Accelerator? 553SN prevents foaming of VE resins containing standard MEKP, such as Butanox M-50.
