B-604 Silver-coated Copper Conductive Coating

Product Description: The B-604 is a conductive paint from Xinshengfeng Technology, made of highly conductive silver-coated copper. It is single-component, labor-saving, time-saving, convenient, has good adhesion, flatness, strong cohesion, and no loose particles. Suitable for the inner wall coating materials of shells for mobile phones, calculators, precision instruments, medical devices, etc., based on plastics and composite materials. After drying and curing, the paint layer maintains stable performance, ideal for single-item and batch spraying production lines.

Technical Specifications:

Color: Silver Bronze

Solids Content (%): 42±2

Density (g/cm²): 1.1 ± 0.05

Viscosity: 8 – 16 s (Paint - 4 cups at 25°C)

Resistor: Less than 0.3Ω/□ (15μm - 20μm dry film)

Spray Area: 3-4 m²/kg (Theoretical Area)

Drying Conditions: 65℃ for 20 minutes

Shelf Life: 6 months (Original Drum)

Instructions for Use:

Surface Treatment for Sprayed Parts: The base material must be clean and dry, free from oil stains and release agents. Clean or soak the surface of the equipment with alcohol or a specialized solvent.

Stirring and Dilution: Thoroughly mix before use to ensure uniformity without sedimentation. No dilution is required for normal use. If dilution is needed, use NEK or our company's diluent (BL-333) to dilute to the required working viscosity. Recommended dilution ratio: Oil 2 parts, diluent 1 part (2:1).

Spraying: W-71 spray gun, orifice size 0.5 – 2mm

Spray gun and object distance: 100 - 200mm

Spray Pressure: 0.4 – 0.6 MPa

Flow rate: 2-4 cycles; Film thickness: 15-25μm

Anti-settling operation: For small parts, return the gun once every 2-3 sprays, and agitate the oil once every 3-4 gun returns.

Large workpieces require a gun return after every 1st spray, and oil mixing must be done after every 4-5 gun returns.

Dry: Naturally dried at 25°C, surface dry in 5 minutes / fully dry in 2 hours

Drying at 65℃ for 20 minutes, followed by a 1-hour rest after drying will yield good resistance.

Cautionary Notes:

Keep away from heat and flame. Prohibitions: sparks, open flame, high temperatures.

Please read the instructions carefully before use.

3. Be cautious during handling, avoid direct contact with skin or eyes, and ensure proper protection measures are in place.
