Sealants

As a professional supplier of electroplating-related solutions, our company offers a comprehensive range of substrate surface treatment products, including cutting-edge post-plating sealants. Our post-plating sealant is specifically designed to prevent surface oxidation, discoloration, and blackening of plated substrates while maintaining conductivity, solderability, and the high-gloss appearance of polished surfaces. Under proper application, treated components retain their integrity and luster for up to 2-3 years at room temperature without degradation. This product is water-based, eco-friendly, and free from hazardous substances such as chromates, fluorides, peroxides, and heavy metals, offering an ideal alternative to traditional sealing agents.

Technical Specifications

Key Advantages

• Superior Protection: It extends the lifespan of plated surfaces by preventing tarnishing, blackening, and oxidation for 2-3 years under normal conditions.
• Non-Toxic & Eco-Friendly: Chromate-free, heavy-metal-free, and compliant with RoHS/REACH regulations. Contains no fluorides, peroxides, or hazardous substances.
• Performance Preservation: It does not compromise conductivity, solderability, or appearance—ideal for electrical contacts, connectors, and decorative finishes.
• Enhanced Durability: It provides mild lubrication to improve wear resistance in high-contact applications (e.g., plugging/unplugging cycles).

Recommended Usage

• Dilution: 10% working concentration (using deionized water)
• Preparation:
  • Add approximately 50% of the total required water to the tank.
  • Introduce 100 mL/L of sealant concentrate.
  • Fill the remaining volume with DI water.
  • Adjust the bath temperature to operating range.
  • Stir thoroughly before use. Shake the product container well before pouring.

Bath Maintenance

• Monitor temperature and bath level regularly. Top up water and sealant concentrate as needed.
• Replace the working solution periodically based on throughput and usage time to maintain optimal performance.
