Curox M303 Catalyst is used with our range of Polyester laminating and gelcoat resins. You may purchase additional catalyst if you are working in a cold environment and wish to accelerate cure time (Please note this is done so at your own risk). Curox M303 is supplied as standard with all our polyester resin kits.

 

Colourless, mobile liquid, consisting of peroxides based on methylethylketone, essentially desensitised with phtalate plasticiser. This ketone peroxide is used as an initiator (radical source) in the curing of unsaturated polyester resins. Main application: gelcoats, curing of moulded, casted or winded glasfibre reinforced products at ambient temperature in combination with cobalt accelerators

  • POLYESTER CURING: Curing agent for all UP resin types at ambient temperature in combination with cobalt accelerators. Standard dosage level: 1-3% as supplied, with 0.5-2% of a 1% cobalt solution. Suitable also for gelcoats with improved osmosis resistance and lowest porosity due to low water- and hydrogenperoxide content. "Pot life" (gel time of resin + peroxide + accelerator) relatively short, but may be prolonged by adding Inhibitors, such as tert.butyl catechol.

     

    CURING PERFORMANCE: Moderate evolution of heat. Relatively long mould release time, moderate mould release factors. Temperatures below 20°C prolong curing times considerably, alternatively cobalt / amine accelerators should then be used.
