Promoter: to reduce the working time and curing the resin

Retardant: to extend the working time of the resin.

Flexible resin, to mix with any polyester and achieve greater tenacity and strength.

Thickening: Aerosil to increase viscosity

Styrene and Paraffin Styrene: to lower the viscosity and eliminate the superficial tacky
