Top 5 applications of salt spray chamber for the easy testing process

The need for a salt spray chamber arises from the necessity to assess the corrosion resistance of materials, coatings, and products in a controlled and accelerated manner. Presto, Asia’s No.1 manufacturer of laboratory testing instruments has designed a high-quality lab testing instrument known as a salt spray chamber. When the materials should be tested against corrosion resistance, then manufacturers of the metal industry can get assurance about the durability of materials against corrosion.

Applications of Presto corrosion test chamber

1. Evaluation of Phosphate Surfaces: Salt spray chambers are extensively used to assess the corrosion resistance of phosphate surfaces that have been subsequently treated with paint, primer, lacquer, or rust preventive coatings. These surfaces are commonly found in various industries, such as automotive, aerospace, and construction, where corrosion protection is crucial.
2. Testing Zinc and Zinc-Alloy Plating: Salt spray chambers are valuable testing instruments for evaluating the corrosion resistance of zinc and zinc-alloy plated surfaces. Zinc coatings are widely used in industries like automotive, electronics, and hardware, where they provide excellent corrosion protection. The chamber helps determine the effectiveness and durability of these coatings in various environments.
3. Assessment of Electroplated Chromium, Nickel, Copper, and Tin: Electroplated metals, such as chromium, nickel, copper, and tin, are commonly used for decorative and functional purposes. Salt spray testing allows manufacturers to evaluate the corrosion resistance of these coatings, ensuring their long-term performance and durability.
4. Testing Non-Electrolytically Applied Coatings: Salt spray chambers are also used to assess the corrosion resistance of coatings that are not applied electrolytically. For example, zinc flake coatings, which are often used in the automotive and construction industries for corrosion protection, can be tested in the chamber to evaluate their resistance to salt spray corrosion.
5. Evaluation of Organic and Paint Coatings: Salt spray chambers are widely employed to test the corrosion resistance of organic and paint coatings. These coatings are applied to various materials, including metals and plastics, to provide protection against corrosion. The chamber allows manufacturers to determine the effectiveness of these coatings in withstanding salt spray exposure, helping them make informed decisions about their usage.
