Sheet Molding Compound (SMC) and Bulk Molding Compound (BMC) are intermediate products which are finally pressed to end products in the hot press at temperature in the range of 150°C, so called Hot Press Molding. During pressing it is possible to use an in-mold coating to finish the exterior of the product during the curing step.

Nouryon curing agents

The SMC/BMC material is prepared with a combination of peroxides and inhibitors to secure sufficient shelf life during storage, while at the same time providing high-reactivity and efficient curing during pressing, leading to low residual styrene levels and high-surface quality.

The main peroxides used in SMC/BMC are Trigonox® 21S in combination with Trigonox C or Trigonox 22-C50.

Alternatively one can choose Trigonox 21LS, which allows for longer storage stability of the SMC/BMC or Trigonox 141 for high reactivity or Trigonox BPIC-C75 for a more smooth cure.

For PMC (in-mold Powder Coating), Perkadox® 14 and Perkadox BC are used which are reactive at high curing temperatures.

Main products

The end products are very diverse and include components for the automotive, electrical and building industry.
