PRODUCT DATA SHEET
SikaBiresin L323 (Formerly EL-323TC)
Lightweight Composite Tooling Compound/ Tooling Dough
TYPICAL PHYSICAL PROPERTIES (FOR FURTHER VALUES SEE SAFETY DATA SHEET)
DESCRIPTION
SikaBiresin
L323 is an epoxy-based,
composite tooling compound designed for
the construction of tools, jigs, models,
sandwich structures and other tooling or
modeling applications. When mixed the
system results in a very pliable elastic
compound which can be applied to the
tool surface without crumbling or cracking.
SikaBiresin
L323 can be applied at any
thickness above ” without excessive
exotherm. Tools constructed with
SikaBiresin L323 maintain a very high
degree of dimensional stability, are light in
weight, and can be machined as well as
drilled and tapped. The SikaBiresin
L323
resin and harder are both syntactic dough
compounds, which minimize splash
hazards, in comparison to standard, room
temperature epoxy laminating systems.
PRODUCT BENEFITS
– Colored resin and hardener for mix
indication
– Pliable and formable with no cracking or
crumbling when mixed
– Can be machined or drilled and tapped
– Low density (lightweight)
– Very low coefficient of thermal expansion
(CTE) for excellent dimensional stability
– Low exotherm build
AREAS OF APPLICATION
SikaBiresin
L323 is ideal for lightweight
composite sandwich tools and structures. It is used
for tools, jigs, fixtures, models, and other
application types. SikaBiresin
L323 can also be
used for artistic formable models.
Tests with actual materials and conditions
have to be performed to ensure satisfactory
performance.

CR96 FR is a halogen- free,
flame retardant, epoxy laminating and
infusion system developed for use in
fabricating parts or repairs on structures
that require flame retardant, self-
extinguishing properties with room-
temperature curing capabilities. The low
mixed viscosity of SikaBiresin CR96 FR
also renders it suitable for vacuum
infusion processes. This system does not
contain PBDE, OBDE, or DBDE flame
retardant additives.

interiors and other areas where flame
retardant performance is required
– Non-halogen flame retardancy
– Self-extinguishing
– Epoxy (non- styrene)
– Excellent bond to all fabrics
– Low viscosity for good wet-out
– Vacuum infusion capable
AREAS OF APPLICATION
SikaBiresin CR96 FR is suitable for vacuum
bagging, infusion, or resin transfer molding
applications. Areas of application include
aerospace, transportation, architectural, and
others.
