SP 4832
MONO-COMPONENT EPOXY SYSTEM
INTRODUCTION
SP 4832 is a highly thixotropic, gap filling paste. It is a single component epoxy system designed to co-cure at
moderate elevated temperature with Gurit s SE prepregs. The product is designed to be either applied between gel
coat and prepreg in sharp recesses in order to bridge any large gaps between the two, or used as a highly effective
low density core splicing adhesive. The colour is a very dark grey, to tone in with carbon prepregs.

INSTRUCTIONS FOR USE
MIXING & HANDLING
SP 4832 resin is a pre-catalysed, mono-component system and
therefore does not need to be mixed with another component.
Because it is pre-catalysed, care should be taken with storage
and handling. The system requires a temperature of 80 C to
cure fully but some polymerisation, which will thicken the
product and affect its handling properties, can occur at lower
temperatures. To ensure safe use the product should not be
used for a long time or stored at ambient temperatures above
40 C.
For long term storage, the product should be stored at -18 C in
a freezer, but it can be kept at room temperature (20 C) for up
to 20 days without affecting the handling and cured properties
too much. If stored in freezer conditions, the product should be
warmed to ambient temperature before dispensing. It should
be returned to the freezer immediately after use.
APPLICATION
The adhering surfaces should be dry, free of grease, oil, or
mould release or similar material, which would prevent
adhesion of the system. The pre-mixed system is available in
cartridges that fit a standard mastic gun, or it can be applied by
pallet knife or by a suitable dispensing/injection system. The
polymerisation reaction of the system does not generate
significant amounts of heat but in a controlled manner without
runaway exotherm and so large volumes in thicknesses up to
25mm can be applied safely.
SP 4832 is resistant to sag even in thicknesses up to 20-25mm
on a vertical surface. It retains its outstanding thixotropy even
at elevated temperature.
CURING
The system is designed to co-cure with Gurit s SE prepregs /
SPRINT
Materials.
A typical cure cycle is 12 hours at 80 C. Other cure times &
temperatures are possible but no data has been determined for
these alternative cure cycles. Exact times for any particular set
of conditions have not been determined and users should
satisfy themselves that adequate properties for the system are
obtained for the particular combination of mixed volume, cure
temperature, and elapsed time.

HEALTH AND SAFETY
The following points must be considered:
1. Skin contact must be avoided by wearing protective gloves.
Gurit recommends the use of disposable nitrile gloves for most
applications. The use of barrier creams is not recommended,
but to preserve skin condition a moisturising cream should be
used after washing.
2. Overalls or other protective clothing should be worn when
mixing, laminating or sanding. Contaminated work clothes
should be thoroughly cleaned before re-use.
3. Eye protection should be worn if there is a risk of resin,
hardener, solvent or dust entering the eyes. If this occurs flush
the eye with water for 15 minutes, holding the eyelid open, and
seek medical attention.
4. Ensure adequate ventilation in work areas. Respiratory
protection should be worn if there is insufficient ventilation.
Solvent vapours should not be inhaled as they can cause
dizziness, headaches, loss of consciousness and can have long
term health effects.
5. If the skin becomes contaminated, then the area must be
immediately cleansed. The use of resin-removing cleansers is
recommended. To finish, wash with soap and warm water.
The use of solvents on the skin to remove resins etc must be
avoided.
Washing should be part of routine practice:
nbefore eating or drinking
nbefore smoking
nbefore using the lavatory
nafter finishing work
6. The inhalation of sanding dust should be avoided and if it
settles on the skin then it should be washed off. After more
extensive sanding operations a shower/bath and hair wash is
advised.
Gurit produces a separate full Safety Data Sheet for all
hazardous products. Please ensure that you have the correct
SDS to hand for the materials you are using before
commencing work. A more detailed guide for the safe use of
Gurit resin systems is also available from Gurit and can be

TRANSPORT & STORAGE
SP 4832 contains resin, hardener and catalyst components. It is relatively latent at room
temperature but can represent a hazard if subjected to excessive heat (>40 C). The
material should ideally be transported frozen and should be stored at -18 C. Its shelf life at
-18 C is 24 months.
SP 4832 should be kept in a secured closed container (max. 25 kg) during transport and
storage. Any accidental spillage should be soaked up with sand, sawdust, cotton waste or
any other absorbent material. The area should then be washed clean (see appropriate
Safety Data Sheet).
