Trigonox® BPIC-CP75, tert-butylperoxy isopropyl carbonate, is an aliphatic percarbonate, which is used for the curing of unsaturated polyester resins at elevated temperatures. Trigonox® BPIC-CP75 is especially developed for the curing of UP resin based Hot Press Molding formulations (SMC, DMC, BMC etc) in the temperature range of 120 – 170°C.
Trigonox® BPICCP75 gives a long shelf life stability of the compound.Trigonox® BPIC-CP75 can in comparison with Trigonox® C, tert-butyl peroxybenzoate, be characterized as a faster and more efficient peroxide.This means a faster and more optimal cure with a lower residual styrene content of the molded part. In combination with an optimal Low Profile or Low Shrink
formulation a very smooth and regular surface of the moulded product can be achieved. The decomposition products of Trigonox® BPIC-CP75 are low volatile compounds, which makes the peroxide very suitable for the production of e.g. microwave cookware. For a further increase of the reactivity, Trigonox® BPIC-CP75 can be used in combination with a high reactive peroxide like Trigonox® 21 or Trigonox® 141.
