TYPICAL PHYSICAL PROPERTIES (FOR FURTHER VALUES SEE SAFETY DATA SHEET)
DESCRIPTION
SikaBiresin CR62 FR is a halogen -free,
flame retardant, epoxy laminating system
developed for use in fabricating parts or
repairs on structures which require flame
retardant, self-extinguishing properties
with room temperature curing abilities.
This system offers two hardener options;
SikaBiresin CH62 (B) is designed for
vacuum bagging or closed mold
applications, while SikaBiresin CH62-1 (B)
Fast is designed for use in fabricating open
mold, hand laminated parts. 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
– Two hardener choices for fast or medium
pot life
AREAS OF APPLICATION
SikaBiresin CR62 FR is suitable for vacuum
bagging, open molding, 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.
