PEROXAN A-40 L
Ketone peroxide / Polymerization / Curing / Crosslinking
PEROXAN A-40 L is used for the curing of unsaturated polyester resins at ambient temperature in combination with cobalt accelerators.
With the curing system PEROXAN A-40 L in combination with a cobalt accelerator a much faster speed of cure may be achieved than with curing systems based on a MEKP plus cobalt accelerator. Normally, the gel times with PEROXAN A-40 L are comparable to those with PEROXAN ME-50 L.
PEROXAN A-40 L 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 PEROXAN A-40 L plus cobalt accelerator will give a higher peak exotherm than a standard MEKP / cobalt accelerator system. Due to this fact, it is recommendable to avoid the production of too thick laminates in one operation. At low temperatures a reasonable speed of cure is still obtained when PEROXAN A-40 L is used in combination with a cobalt amine accelerator, e.g. PERGAQUICK C24 AX, which contains N,N-Dimethylaniline as promotor.
Depending on working conditions, the following peroxide and accelerator dosage levels are recommended:
PEROXAN A-40 L: 1,0 to 3,0 phr
PERGAQUICK C12 X (Cobalt, 1%): 0,5 to 2,0 phr
Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN A-40 L. This information should be thoroughly reviewed prior to acceptance of this product. The MSDS is available for downloading at www.pergan.com or through contacting Pergan directly.
