SikaBiresin CR86 with CH86- 2 (Fast), CH86- 3 (Medium), CH86-6 (Slow) hardeners
(FORMERLY PROINFUSION RT)
EPOXY INFUSION SYSTEM
VARIABLE HARDENERS, 250 CPS MIXED VISCOSITIES
DESCRIPTION
SikaBiresin CR86 is designed for production of composite structures by infusion or other methods
and offers three different hardener choices for variable pot life / working times for consideration
of part size and gel time set-up speeds. Applications include composite tools or parts for marine,
and several other areas. The system is suitable for infusion processing along with wet-layup,
vacuum bagging, and RTM processes.
PROPERTIES
High clarity
R.T. cured and post-cured options
Variable pot life/working time options
Very low mixed viscosity
Excellent ultimate properties
Hardener blending an option

PROCESSING
After mixing according to the indicated ratio, carry out impregnation of the reinforcements.
To ensure an optimal use and a good impregnation, please use packaging stored at a temperature
above 15 C.
CURE CONDITIONS
In order to avoid any risk of distortion or tooling shrinkage a precise curing cycle must be observed.
Demolding takes place only after a 24 hour R.T. minimum or 16 hour pre-curing at 40 C-60 C. material
can be used with R.T. cure only or with some (Post-cure) carried out.
HANDLING PRECAUTIONS
Normal health and safety precautions should be observed when handling these products :
Ensure good ventilation.
Wear gloves, glasses and protective clothes.
For further information, please consult the Safety Data Sheets.
STORAGE CONDITIONS
Shelf life of resin and hardeners are 12 months in original, unopened container stored in a dry 65-
77 F (18- 25 C) place.
Repeated exposure to low temperatures during storage may cause the resin to crystallize. If this
occurs, warm the resin to 120 – 140 F (49 -60 C) and stir to dissolve the crystals. Any opened can
must be tightly closed.
