SE 180
5 MINUTE CURING PREPREG
Epoxy Prepreg Optimised for Press Moulding Applications
Developed for Automotive Component Production
Good Surface Finish
Net Shape Components
Hot-in, Hot-out Press Processing
5 Minute Cure Time at 150 C
INTRODUCTION
SE 180 Prepreg has been specifically developed for high
volume press moulding applications and enables users to
perform cycle times of 5 minutes.
The products characteristics facilitate simple preforming prior to
moulding and the ability to fill edged detail during moulding,
allowing net shaped parts to be manufactured.

PREPREG PROPERTIES
PROCESING INFORATION
SE 180 can be cured at varying temperatures above 130 C. Cure
times are shown in the table below. Press closure cycle needs to be
determined by users as optimum press cycle will depend on part
and mould shape. Press closure needs to occur before gelation of
the resin, indicative gelation times are given below.
TRANSPORT & STORAGE
Store sealed & out of direct sunlight. Frozen transport should
be used when transferring between sites.
The storage time at 21 C is determined as the point that
changes in handling characteristics of the prepreg are evident
(tack and drape). As the prepreg resin reacts at room
temperature (21 C) changes in resin flow and minimum
viscosity can be observed this could affect the processing
characteristics of the prepreg.

All prepreg materials should be stored in a freezer when not in
use to maximise their useable life, since the low temperature
reduces the reaction of resin and catalyst to virtually zero.
However, even at -18 C (0 F), the temperature of most
freezers, some reaction will still occur. In most cases after
some years, the material will become unworkable After
removal from cold storage prepreg should be allowed to warm
to room temperature before plastic bag is removed to prevent
condensation.
