DESCRIPTION
SikaBiresin
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.
PRODUCT BENEFITS
– Meets FAR 25.853 flame testing for aircraft
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.
Tests with actual materials and conditions
have to be performed to ensure satisfactory
performance.
