CC3-402  

 

 

General Purpose Potting Resin

 

CC3-402 is a general purpose, mineral filled epoxy potting resin exhibiting low abrasion resistance. It is

designed to be used where low viscosity and good wetting-out properties are important. Low shrinkage

and good thermal shock resistance minimize stress on potted components.  A choice of hardeners enable

the CC3-402  to be cured either at room temperature or with heat. Even though the entire CC3-402 series

offers a low percent of filler separation, it is advisable to always mix the contents in the shipping container

prior to use.

CHOICE OF HARDENERS:

 

H-1 Hardener:                         Rigid, good dimensional stability, fast cure.

 

H-7 Hardener:                         Resilient, excellent mechanical and thermal shock, low viscosity,

good air release, fast cure.

 

Ancamine Z:                           Resilient, excellent mechanical and thermal shock, plus high heat

distortion, long pot life.

 

H-10LV Hardener:                  Variable hardness, excellent impact properties, long pot life

ROOM TEMPERATURE CURE:

 

H-1 Hardener:                         Cures overnight at room temperature or 2 hrs at 65’ C.

Do not heat cure if the mass exceeds 200 grams.

 

H-7 Hardener:                         Cures overnight at room temperature or 2 hrs at 65’ C.

                                                Do not heat cure if the mass exceeds 200 grams.

 

H-10LV Hardener:                  Cures overnight at room temperature or 3 hrs at 65’ C.

                                                Do not heat cure if the mass exceeds 300 grams.

 

 

HEAT CURE:

 

Ancamine Z:                           Cures overnight at 65’ C or 3 hrs at 125’ C. For best physical and electrical properties, a slow cure for 16 hours at 65’ C followed by a post cure for 3 hours at 125’ C is recommended.

 

 

MIXING INSTRUCTIONS:

 

Mix CC3-402 thoroughly in it’s shipping container to insure a uniform consistency. Weigh out the desired amount of resin in a clean container. Add the hardener accurately by weight in the proper proportion as specified above. (ie. 7.0 grams of H-1 Hardener and 100 grams of CC3-402 for a total mix of 107.0 grams) Mix thoroughly. Use in a well ventilated area and avoid contact with eyes and skin.
