Characteristics

Acrylic Polyurethane Topcoat offers the following key features:

Smooth and Even Finish: The coating forms a smooth, uniform surface with excellent mechanical properties and outstanding weather resistance.

High Gloss: The paint film delivers a high-gloss finish that can replicate the appearance of aluminum-plastic composite panels, providing an exceptional metallic texture and luster.

Chemical Resistance: It demonstrates excellent resistance to acids, alkalis, various chemical agents, and salt spray.

High Hardness: The coating features a high degree of hardness and strong adhesion, making it resistant to scratches and abrasion.

Environmentally Friendly: Some formulations of acrylic polyurethane topcoat have passed environmental safety tests, with low residual VOC content, making them suitable for export-oriented enterprises.

Application Scope

Acrylic Polyurethane Topcoat is widely used in surface finishing applications where high decorative performance is required, including:

Vehicles: Exterior painting of automobiles, motorcycles, bicycles, and other transportation equipment.

Metal Packaging: Coating for metal containers such as cans and beverage tins.
Hardware Components or Metal Parts: Surface treatment for various metal fittings and hardware items.

Plastic Products: Certain formulations are also applicable to the coating of plastic components.

Application Methods

Acrylic Polyurethane Topcoat can be applied using various methods, including spraying, brushing, and rolling. The standard application procedure includes the following steps:

Thorough Mixing: Prior to application, ensure the paint is thoroughly mixed to achieve a uniform consistency.
Dilution: If necessary, dilute with deionized water or clean tap water to adjust to the desired viscosity.
Application Temperature: Optimal application temperature ranges from 5°C to 40°C; performance improves under suitable humidity conditions.
Drying Time: Drying time varies depending on temperature. At 20°C, surface dry time is approximately 20 minutes, while full curing typically requires 72 hours.

Recoating Interval: The recoating interval also depends on ambient temperature, generally ranging from 30 minutes to 2 hours.
