PRODUCT DATA SHEET
SikaBiresin CR101 (Formerly EL-335)
Toughened Epoxy Laminating System with High Impact Resistance
TYPICAL PHYSICAL PROPERTIES (FOR FURTHER VALUES SEE SAFETY DATA SHEET)
DESCRIPTION
SikaBiresin CR101 is a high-performance,
toughened laminating system developed for
intermediate temperature laminating
applications up to approximately 225 F
(107 C). SikaBiresin CR101 composites exhibit
increased impact resistance in the fabrication
of parts which will be used in a intermediate
heat temperature environment where
stability and performance are required.
SikaBiresin CR101 is availble with a choice of
two hardener options with different pot lifes
for process flexibility.
PRODUCT BENEFITS
– For applications up to approximately 225 F
(107 C)
– High impact resistance and toughness
– Two hardener choices (fast and slow)
– Excellent cloth wet -out
– Good elongation
– Increased hardness at elevated
temperatures
– Excellent dimensional stability
– Good mechanical shock properties
AREAS OF APPLICATION
SikaBiresin CR101 is used for
prototypes, patterns, master models,
tough composites parts, trim, holding
and checking fixtures, intermediate
temperature use splash molds, and
potting bushings. SikaBiresin CR101 c an be
used for laminating with graphite, EL-Glass,
S-Glass and Kevlar fabrics.
Tests with actual materials and conditions
have to be performed to ensure satisfactory
performance.
