This test examined the effect of vari

ous initiators on the curing behav

iour of a glass fibre-filled polyester

resin using a laboratory mixer.

Initiators are chemical substances

which form so- called radicals under

the influence of energy (e.g. heat)

and which are thus able to initiate

curing reactions.

The processability of thermosetting

resins can be influenced by selecting

the right initiators and this way to

control the reaction time.
