What Are the Formulas for Automotive Paint Mixing?

1 Answers

Automotive paint mixing generally involves four basic formulas: film-forming substances (resins), pigments (including extender pigments), solvents, and additives. Below is more information about automotive paint mixing: 1. Traditional automotive paint coating process: The traditional automotive paint coating process consists of four layers: electrophoretic primer, mid-coat paint, basecoat, and clearcoat. Among these, the electrophoretic layer provides anti-corrosion protection; the mid-coat paint helps the paint achieve better coloration; the basecoat is the most critical step; and the clearcoat enhances the gloss and hardness of the paint surface. 2. What is automotive spray painting: Automotive spray painting refers to applying a layer of paint to the car's surface to protect it. Automotive spray painting typically uses baking paint. In automobile manufacturing plants, after the frame and body are welded, the next step is spray painting. Types include standard paint, metallic paint, and pearl paint. The automotive spray painting process includes applying putty, sanding, and painting. 3. Classification of automotive paint: Automotive paint has undergone three major leaps in history: alkyd (enamel) paint in the 1920s, acrylic (enamel) paint in the 1960s, and clearcoat (urethane) in the 1980s. For easier understanding, automotive paint can be simply categorized into standard paint and clearcoat (mirror-finish clearcoat).

What is the warranty period for car batteries?

Car batteries generally have a one-year warranty period. The warranty duration is calculated from the date of vehicle purchase. Additional information: Below are precautions for battery maintenance: 1. Avoid long-term outdoor parking: Refrain from leaving the car parked in open-air parking lots for extended periods. If long-term parking is necessary, the battery must be removed and taken away to prevent freezing damage. 2. Engine starting: Car engines are harder to start in winter. Each starting attempt should not exceed 5 seconds, with intervals of no less than 15 seconds between attempts. If the engine fails to start after multiple attempts, check other aspects such as the electrical circuit, ignition coil, or fuel system. Avoid continuous starting attempts, as this may cause the battery to over-discharge and burn out. 3. Charging issues: Unused batteries will gradually self-discharge until they become unusable. Therefore, start the car periodically to recharge the battery. 4. Regularly inspect battery components and connections: Clean the battery terminals periodically and apply specialized grease to protect the wiring harness.
