Cast-Coat Inc. CC3-402

Cast-Coat Inc. 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.

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-18 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.

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.
