PERGAQUICK A150 PM
Amine accelerators / Polymerization / Curing / Crosslinking
The curing of unsaturated polyester resins at ambient temperatures can in general not be performed by an organic peroxide alone. The radical formation which is necessary - to start the polymerisation reaction - is too slow at ambient temperatures with most generally applied organic peroxides.
To speed up the radical formation in a controllable way, organic peroxides must therefore be used in combination with a so called accelerator. For diacyl peroxides like Dibenzoyl peroxide - the PEROXAN BP-types - aromatic tertiary amines have to be used as accelerator.
The following amines are available:
N,N-Dimethyl-p-toluidine PERGAQUICK A100 (high reactivity)
Ethoxylates of p-toluidine PERGAQUICK A150 PM (high/medium reactivity)
N,N-Dimethylaniline PERGAQUICK A200 (medium reactivity)
N,N-Diethylaniline PERGAQUICK A300 (low reactivity)
Each amine type has a different and specific influence on the decomposition of Dibenzoyl peroxide. Therefore, it is possible to adjust a wide variety of gel times and speed of cure by the proper choice of amine type and dosage level.
The cure system Dibenzoyl peroxide / amine accelerator can be characterized as being:
- not sensitive for moisture
- practically not sensitive to pigments and fillers
- applicable at low temperatures
Possible disadvantages can be:
- a limited pot life of the amine accelerator in the resin
- yellow to brown colour of the cured product
- poor UV light stability of the cured product
- a relatively high residual styrene content in the mouldings after a postcure at elevated temperature
especially at high amine accelerator dosages.
A special application of the amine accelerator is their use as promotor in a ketone peroxide / cobalt accelerator cure system. For this application mainly PERGAQUICK C24 AX is used.
Depending on application area and working conditions, the following accelerator dosage levels are recommended:
PERGAQUICK A150 PM: 0,2 to 0,5 phr
