Usually it is combined with a peroxide initiator such as cyclohexanone peroxide or peroxide It should be matched with methyl ethyl ketone, the general dosage is about 0.2%-2.5% of the resin. At present, TC-D promoter is widely used in the molding of FRP products, especially suitable for casting buttons, artificial agate, Polaroid board, polyester furniture and light-colored handicrafts.

Appearance: clear  purple liquid

Resin casting body color: original resin color
