Thermoset composites
Detailed description
Trigonox® BPIC-CL75, tert-butylperoxy isopropyl carbonate, is an aliphatic percarbonate, which is used for the curing of unsaturated polyester resins at elevated temperatures. Trigonox® BPIC-CL75 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® BPIC-CL75 gives a long shelf life stability of the compound. Trigonox® BPIC-CL75 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 moulded 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-CL75 are low volatile compounds, which makes the peroxide very suitable for the production of e.g. microwave cookware. Trigonox® BPIC-CL75 can be used in combination with highly reactive peroxides such as Trigonox® 21 or Trigonox® 141 to further enhance activity.
