AI Technical Summary
Existing coatings for automotive plastic parts cannot simultaneously meet the requirements for adhesion, water resistance, and appearance, resulting in the need for secondary coating, which leads to low production efficiency and high costs.
It employs a multi-component formulation of medium-hydroxyl acrylic resin, low-hydroxyl acrylic resin, polycarbonate resin, and high-hydroxyl acrylic resin, achieving high weather resistance, adhesion, leveling, and appearance through a one-coat process. Nano black paste is used to provide color coverage, while additives and curing agents enhance crosslinking density.
It achieves the performance of a two-coat process with a single coating, improving production efficiency, reducing costs, and ensuring the long-term maintenance of a high-gloss paint finish on the vehicle's exterior in various climatic environments.
