Measures to address poor adhesion of painted aluminum die-cast parts for marine vessels.
Identify the poor adhesion caused by insufficient degreasing. Explanation of the important process.
In the hull of marine parts, durability and reliability under harsh environments are required. In particular, the painting of aluminum die-cast parts poses a significant challenge, as poor adhesion of the paint film can directly affect product lifespan and safety. Paint peeling can be caused by various factors such as salt damage, water pressure, and physical impacts, but one of the root causes is inadequate degreasing processes. Residual release agents and processing oils on the material surface hinder direct adhesion between the paint and the material, and even trace amounts of oil that are not visible can compromise long-term durability. While there may be no issues immediately after painting, peeling can occur over time, often leading to additional costs such as re-coating or handling complaints. The first step in addressing poor adhesion is to standardize the degreasing process and review management conditions. 【Application Scenarios】 - Painting of hull parts for ships - Use in harsh marine environments - Ensuring long-term durability of the paint film 【Benefits of Implementation】 - Reduction of paint peeling risks - Improvement of product reliability - Reduction of re-coating costs
