    Trigonox 44B VRN is an acetyl acetone peroxide formulation for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures.With the curing system Trigonox 44B VRN/cobalt accelerator a much faster speed of cure may be achieved than with curing systems based on a MEKP plus cobalt accelerator, at room and elevated temperatures. Normally the gel times with Trigonox 44B VRN are comparable to those with Butanox M-50.Trigonox 44B VRN is particularly suitable in those applications where a fast mould-turnover is required, e.g. for the cold press moulding or resin injection moulding techniques.The system Trigonox 44B VRN/cobalt accelerator will give a higher peak exotherm than a standard MEKP/cobalt accelerator system. Due to this fact, is it recommendable to avoid the production of too thick laminates in one operation. At low temperatures a reasonable speed of cure is still obtained when Trigonox 44B VRN is used in combination with large amounts of cobalt accelerator possibly in combination with AcceleratorNL-63-100 (N,NDimethylaniline) as promotor.
