PEROXAN BP-Paste 50 PF 1 is a paste without phthalate used for the curing of unsaturated polyester resins at ambient temperature in combination with a tertiary amine accelerator. PEROXAN BP-Paste 50 PF 1 has been developped for the curing of putties, e.g. for car repair kits. PEROXAN BP-Paste 50 PF 1 shows excellent chemical and physical stability and is therefore very suitable for cartridge and tube filling. The rheological behavior of PEROXAN BP-Paste 50 PF 1 is that of a thixotropic long paste with a tendency of tailing. PEROXAN BP-Paste 50 PF 1 is available in different colors. The curing system PEROXAN BP-Paste 50 PF 1 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-Paste 50 PF 1: 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-Paste 50 PF 1: 2 to 5 phr Amine accelerator: 0,05 to 0,5 phr Curing according to DIN 16945 (20g Orthoptalic resin in a double-walled test tube at 21°C) PERGAQUICK A150 PM 0.3% mit PEROXAN BP-Pulver 50 W+ 4% PERGAQUICK A150 PM 0.15% mit PEROXAN BP-Pulver 50 W+ 4% PERGAQUICK A150 PM 0.5% mit PEROXAN BP-Pulver 50 W+ 2% PERGAQUICK A150 PM 0.3% mit PEROXAN BP-Pulver 50 W+ 2% PERGAQUICK A150 PM 0.15% mit PEROXAN BP-Pulver 50 W+ 2% 100 200 300 400 500 600 700 800 900 1,000 1,100 1,200 1,300 1,400 1,500 1,600 1,700 1,800 0 20 40 60 80 100 120 140 160 Time in s Temperature in °C Curing according to DIN 16945 (20g BPA vinylester resin in a double-walled test tube at 21°C) PERGAQUICK CP-24 A 0.5% mit PEROXAN BP-Pulver 50 W+ 4% PERGAQUICK CP-24 A 0.2% mit PEROXAN BP-Pulver 50 W+ 4% PERGAQUICK CP-24 A 0.5% mit PEROXAN BP-Pulver 50 W+ 3% PERGAQUICK CP-24 A 0.2% mit PEROXAN BP-Pulver 50 W+ 3% PERGAQUICK CP-24 A 0.5% mit PEROXAN BP-Pulver 50 W+ 2% PERGAQUICK CP-24 A 0.2% mit PEROXAN BP-Pulver 50 W+ 2% 1,000 2,000 3,000 4,000 5,000 6,000 7,000 8,000 9,000 10,000 11,000 12,000 13,000 14,000 0 10 20 30 40 50 60 70 80 90 100 110 120 130 Time in s Temperature in °C
