SMM A00 Aluminum Ingot(CNY/mt)
On May 21, the price of SMM A00 aluminum increased by CNY 100/Mt to CNY 20,320/Mt compared with the previous trading day.The US dollar index fell for two consecutive days and the aluminum prices were supported. Aluminum ingot inventory has accumulated a small amount of 458,000 tons, a decrease of 4,500 tons from the previous month. Yesterday, LME aluminum inventory decreased by 3,000 tons to 391,000 tons.
Last week, the start-up of various downstream aluminum sectors continued to pick up, but due to the influence of various foreign policies, the high tariff level and the high aluminum price, the concerns about future demand still exist, causing downstream consumption to wait and see and the export performance of various downstream aluminum sectors has fallen significantly. This week, the export performance of aluminum products (aluminum plates, color coated aluminum coils) has gradually recovered.

Daily Questions about Color Coated Aluminum Coils
What is the cause of coating sagging in colored aluminum coils?
Uneven surface of aluminum substrate: Uneven surface of aluminum substrate and not timely treatment will lead to uneven thickness of coating, and causing thicker part sagging
Unclean surface of aluminum substrate: When grease, dust or other contaminants on the surface of aluminum substrate are not thoroughly cleaned, poor coating adhesion will lead to coating sagging or peeling.
High viscosity of coating: High viscosity coating will flow unevenly during processing, leading to coating sagging.
Coating thickness too thick: Too thick coating cannot be completely cured, leading to sagging or paint peeling of color coated aluminum coil coating
Uneven coating application: Inconsistent coating speed and pressure will lead to uneven coating thickness and sagging.
Insufficient curing: If the curing temperature is low or the curing time is insufficient, the coating may not be fully hardened and cured, leading to coating sagging or surface stickiness.
How to avoid coating sagging of colored aluminum coil?
Before coating, the surface of the aluminum coil should be thoroughly cleaned to remove any dirt, grease or contaminants that may affect coating adhesion. Choosing high-quality coating with good adhesion and anti-sagging properties and paint evenly to control the film thickness. When curing,the curing temperature should be set according to the coating thickness to ensure that the coating is fully cured and has maximum adhesion.
