styrene copolymerization initiator UP resin initiator

Trigonox® BPIC-C75 Product Description styrene polymerization copolymerization initiator UP resin initiator Trigonox BPIC-C75, full name tert-butylperoxyisopropyl carbonate, is an aliphatic percarbonate used for curing unsaturated polyester resins at high temperatures. Specially designed for curing UP resin-based hot pressing formulations (SMC, DMC, BMC, etc.) in the temperature range of 120-170 °C. Trigonox BPIC-C75 is a recognized faster and more efficient hydrogen peroxide compared to Trigonox C, tert-butyl peroxybenzoate. This means faster, better curing with lower residual styrene content in the molded part. Combined with the optimum low profile or low shrinkage formulation, a very smooth and regular molded product surface can be achieved.  …
