Passivation Solution

Core Value: Corrosion Resistance, Quality Preservation, Durability

Breaking traditional anti-corrosion limits (oiling, simple painting), this solution integrates "strengthened protection, performance preservation and cost reduction"—widely used in metal processing.

Ideal Application Scenarios

Widely used in long-term anti-corrosion needs:

Auto Parts: Engine fasteners, chassis components (resists road salt/humidity corrosion).

Hardware & Standard Parts: Bolts, nuts, hand tools (prevents rust; maintains appearance).

Construction & Steel Structures: Outdoor steel components, guardrails (improves weather resistance).

Electronic Products: Metal shells, connectors (ensures stability; prevents corrosion-induced contact failure).

Aerospace & Precision Parts: Meets strict anti-corrosion requirements without affecting dimensional accuracy.

Usage & Professional Support

1. Simple Usage

New Solution Preparation: Dilute the passivation solution with tap water at a ratio of 1:10-20 (adjust by metal); 20-40℃ for use.

Existing Lines: Add directly to treatment tank (no equipment modification).

Post-Treatment: Rinse with clean water; dry naturally or bake at 50-80℃.

2. Professional Support

One-stop services: customized formula adjustment, on-site process guidance, regular solution performance testing.

Key Advantages

• Superior Corrosion Protection

  High-barrier passive film boosts salt spray/humidity/chemical resistance. Salt spray resistance ×3-5; lifespan ×2+; prevents rust, discoloration and peeling.

• Performance Preservation

  Ultra-thin film (several to tens of μm) with good toughness—no impact on workpiece size, strength or conductivity. Compatible with subsequent assembly/welding/painting.

• Eco-Safe

  Chromate-free, low-toxic (no Pb/Hg/hexavalent Cr). Complies with RoHS; avoids pollution and health risks of traditional solutions.

• High Compatibility & Efficiency

  Suitable for carbon steel, stainless steel, aluminum/zinc alloys, galvanized parts. Simple processes (immersion/spraying/brushing); 3-15min treatment; integrates seamlessly into existing lines.

   

• Stable & Economical

  Solution stable for 15-30 days of continuous use. Reduces replacement frequency; 30% lower per-square-meter cost than traditional solutions.
