CC3-301AD-FR

UL-94V-0 FIRE RETARDANT

THERMALLY CONDUCTIVE, LOW VISCOSITY POTTING RESIN

CC3-301AD-FR is a fire retardant version of CC3-301AD. It offers the same excellent heat transfer, high voltage insulation and dimensional stability over a wide temperature range. As an encapsulant for power devices, it distributes heat evenly throughout the casting; providing greater efficiency and a longer working life. This compound has good wetting properties and low surface tension. Its high fluidity and good air release recommend it for potting intricate circuitry. Glass diodes potted in CC3-301AD-FR have shown good resistance to cracking under severe temperature cycling. The filler used in CC3-301AD-FR may settle out during storage. It is very important to stir the material in the shipping container prior to use.

CC3-301AD-FR meets MIL T-27, Grade 5, Class H; MIL STD. 202.111, FED TEST METHOD STD. 406-2021; MIL 1-16923, Types C and D; and UL-94V-0.

TYPICAL APPLICATIONS
Densely packaged power supplies, integrated circuits, thick film hybrid devices, D/A converters, delay lines, oscillators, minidac, operational amplifiers, binary devices, relays, transformers and semiconductors.

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.
H-lOLV HARDENER

- Cures overnight at room temperature or 3 hours at 65'C.
HEAT CURE
 
H-34 HARDENER


- Cures over night at 65'C or 4 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 4 hours at 125'C is recommended.

MIXING INSTRUCTIONS

Mix CC3-301AD-FR 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.
