Coated Aluminum Coil For Sale

The coated aluminum coil for sale is a high end aluminum product that are used in our daily life with beautiful appearance. Below are the various testing techniques and their importance to ensure the quality of color coated aluminum coil.

1, Film thickness of color coated aluminum coil:

Having the proper paint film thickness is critical to the long-term performance of the paint film. For primers, low film thicknesses may result in premature corrosion or poor adhesion. For topcoats, low thickness films may cause premature failure due to weathering.

2, The color of color coated aluminum coil for sale:

One of the main reasons for purchasing prepainted products is to provide a specific colored look. Since it is common for customers to match prepainted metal to other components of a building or product, matching specified color standards is important to the aesthetics of the final assembled product. For repeating colors, matching the criteria each run ensures that the colors remain consistent over time. Color must be consistent across the width of the strip and from coil to order. Many factors can affect color: paint formulation and quality, film thickness, substrate color, curing temperature (PMT) and dwell time in the curing oven, and even contamination from other paints.

3, Glossiness of color coated aluminum coil:

Gloss consistency is important to provide clients with a uniform look. The final product may consist of several components made from different coils. If the gloss level is not consistent, the final product will have a poor appearance and will not look good.

4, Adhesion of color coated aluminum coil for sale:

Several tests were performed to check various aspects of adhesion, including T-bend, impact and various scratch tests. Pre painted aluminum coil can undergo many types of forming to transform them into final products such as curved types in siding or roof construction, embossed garage doors, residential doors, ceiling grids, home and office furniture, pressed Flower refrigerators, drink cans and lids etc. One of the main advantages of prepainted aluminum coil is that it can be formed after painting, so these tests are very important to ensure that the paint will not be damaged or removed during subsequent processing. Factors that affect adhesion include paint formulation, film thickness, curing temperature (PMT), line speed, quality of treatment, aluminum and steel quality and cleanliness.
