Painting Coating

  • Q Is it environmentally friendly?

    A

    Yes, low-VOC options help reduce pollution.

  • Q What is the difference from zinc plating?

    A Coating is a spray process, not an electrochemical one.

  • Q How effective is its corrosion resistance?

    A Provides good cathodic protection, though not as durable as hot-dip galvanizing.

  • Q Is it suitable for on-site repair?

    A Yes, easy to maintain and reapply when needed.

  • Q What is the thickness range of zinc coating?

    A 10-100μm, adjustable depending on application.

  • Q Is it environmentally friendly?

    A Yes, chrome-free options help reduce pollution.

  • Q What is the difference from zinc coating?

    A Zinc plating is an electro/thermal deposition process, while coating is a spray application.

  • Q Is it suitable for outdoor use?

    A Yes, it provides strong resistance to atmospheric corrosion.

  • Q Does it sacrifice itself for protection?

    A Yes, the zinc layer corrodes first to protect the base metal.

  • Q What is the thickness range of zinc plating?

    A 5-150μm, depending on the process.

  • Q Is it suitable for high-frequency applications?

    A Yes, low resistance reduces signal attenuation.

  • Q What are its advantages compared to gold plating?

    A Lower cost and better conductivity, but more prone to oxidation.

  • Q How effective is its antibacterial property?

    A Naturally inhibits bacteria, suitable for hygienic applications.

  • Q Will it turn black?

    A Possibly, but after passivation it remains stable; environmental resistance is tested.

  • Q What is the thickness range of silver plating?

    A 1-25μm, thin layers are for contact, thicker layers for protection.

  • Q How is coating purity controlled?

    A Electrolytic parameters and testing ensure 99.9% pure gold.

  • Q What are its advantages compared to silver plating?

    A Better oxidation resistance but higher cost; ideal for high-reliability applications.

  • Q Is it suitable for medical applications?

    A Yes, it is biocompatible and tested for allergy risks.

  • Q Will it oxidize or discolor?

    A No, gold layers are highly stable with excellent oxidation resistance.

  • Q What is the thickness range of gold plating?

    A 0.5-5μm, thin layers are for contact surfaces, thicker layers for protection.
