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 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 before using.

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. |
| H-34 HARDENER |
- resilient, excellent mechanical and thermal
shock, plus high heat distortion, long pot life. |
| H-lOLV HARDENER | - variable hardness, excellent impact properties, long pot life. |

ROOM TEMPERATURE CURE
| H-1 HARDENER |
- Cures overnight at room temperature or
2 hours at 65'C. Do not heat cure if the mass
exceeds 200 grams. |
| H-7 HARDENER |
- Cures overnight at room temperature or
2 hours at 65'C. Do not heat cure if the mass
exceeds 200 grams. |
| H-1OLV HARDENER | - Cures overnight at room temperature or 3 hours at 65'C. Do not cure if mass exceeds 300 grams. |
HEAT CURE
| H-34 HARDENER | - Cures over night at 65'C or 3 hours at 125'C. For the 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 its shipping container to insure a uniform consistency. Weigh out the required amount of resin in a clean container. Add the hardener accurately by weight in the proper proportion as specified above. Mix thoroughly.
Use in a well ventilated area and avoid contact with eyes and skin.
