Quick drying conformal coating - 10min, no-clean
5.0/5 rating 1 vote

We are a professional quick drying conformal coating producer from China. This product is one-component, light yellow transparent liquid with 10 minutes skin-over time, 3 hours curing time.  It has a strong adhesion, flexible and small stress after the formation. No free radicals, no corrosive, no damage to electronic component, a wide working temperature range. A high softening point after the formation, sticky at 130 ℃, but not drip (no damage to electrical insulation). It has a good stability to chemicals such as phenol, alkali, salt. Perfect characteristic of anti-salt fog, anti-mold, anti-humidity, and rapid film-forming.

Attention

Drying time:
Skin-over time 10min, curing time 3~5h a
t room temperature 25℃
completely cured
30min at 60℃.

Operating process:
1. Coating operation should be carried out in good ventilation conditions, prevent exposure to fire.
2. When air pressure is low and humidity, circuit board should be placed in oven 30 minutes  at
60℃ to remove moisture. Film will be shiny and bright while coating hot circuit board.
3. When performing the second coating, ensure the first layer is fully cured.
4. Tools used in operating process must be kept dry and clean. Keep away from water, dust during c
oating process.
5. Volatile solvent caused viscosity gradually thickening, please add our special dilution.


Storage:
Store in a cool, ventilated, dry warehouse, Keep away from open flames, direct sunlight.

Shelf life:
18 months(
