Coating, Grease, Repair

1. Coating

1) Technical Features:

Utilizing nano-scale composite coating materials, it offers high-temperature resistance (-40°C to 260°C), corrosion resistance (salt spray test ≥ 500h), and insulation resistance > 1012Ω.

 

Products include conformal coatings (acrylic/polyurethane/silicone), conductive silver pastes, and optical coatings.

 

2) Typical Applications:

▶ PCB moisture-proofing (IPC-CC-830B compliant)

▶ Automotive electronics salt spray coating (AEC-Q100 certified)

▶ Radiation-resistant coatings for aerospace components (meets MIL-I-46058C requirements)
