PEROXAN BP-40 LS

PEROXAN BP-40 LS is used for the curing of unsaturated polyester resins at ambient temperature in combination with a tertiary amine accelerator. PEROXAN BP-40 LS is easy to handle, easy to disperse and dissolves quickly in unsaturated polyester. Moreover, PEROXAN BP-40 LS is suitable for continuous metering using automatic dosing equipment. The curing system PEROXAN BP-40 LS in combination with an amine accelerator shows a very fast cure that is hardly influenced by humidity and fillers. Even at low temperatures a relatively good cure will be obtained. A disadvantage may be the yellow color and poor light resistance of the molded product. For ambient temperature curing the following amine accelerators are available to adjust the gel time and speed of cure of the cure system based on PEROXAN BP-40 LS: PERGAQUICK A100 (N,N-Dimethyl-p-toluidine) for short gel times PERGAQUICK A150 PM (Ethoxylates of p-toluidine) for short to medium gel times PERGAQUICK A200 (N,N-Dimethylaniline) for medium gel times PERGAQUICK A300 (N,N-Diethylaniline) for long gel times Depending on working conditions the following peroxide and accelerator dosage levels are recommended: PEROXAN BP-40 LS: 2 to 5 phr Amine accelerator: 0,05 to 0,5 phr
