This conformal coating creates a high‑density insulating barrier that protects electronic components from moisture, contaminants, and electrical shorts. Its waterproof, fast‑drying formula is easy to apply—just clean, coat, and let it cure for 24 hours. Designed for a wide range of circuit boards as well as for RC applications such as receivers and flight controllers. FEATURES: High‑density insulating barrier protects electronic components Waterproof formula blocks moisture and contaminants Helps prevent electrical shorts and extends component life Simple application: clean, coat, and air‑cure for 24 hours Fast‑drying, smooth‑flowing varnish with automatic gap filling Withstands temperatures from -40°C to 130°C Suitable for aerospace, industrial, automotive, and household circuit boards Ideal for RC electronics such as receivers and flight controllers SPECIFICATIONS: Product Name: Conformal Coating Content: 100ml Product size: about 4.5x9.5cm / 1.7x3.8inches INSTRUCTIONS: Before use: The surface of the object must be cleaned first and kept dry Preparation: Stir or shake the circuit board insulating varnish The first application: You can use a brush to apply it to the circuit board to keep the coating thin and even The Second application: Apply it to your circuit board again after an interval of 5 to 10 minutes to achieve the best adhesion effect Curing: After application, place it in a clean and well-ventilated environment to cure naturally (surface drying takes about 10-30 minutes, full drying takes 24 hours). INCLUDES: (1) Bottle of Conformal Coating(1) Brush NOTES: Not recommended to be used on connectors or ESC.
