During winter, the melting snow salt on the roads and the continuous erosion of muddy water during the rainy season can easily cause perforation and rusting of the car chassis. The chassis armor anti-corrosion coating made by combining emulsified silicone oil and organic silicone resin has become the standard protective layer for the chassis of the entire vehicle. It has outstanding water repellent and corrosion isolation performance.
After the silicone oil coating is sprayed onto the chassis steel plate and suspension metal parts, it forms a flexible waterproof film with extremely low porosity. The salt spray test can reach over 1000 hours, which is much better than ordinary rubber-type chassis armor. The unique water repellent property of the silicone oil prevents muddy water and melting snow salt from penetrating into the metal gaps, effectively inhibiting electrochemical corrosion from its source; the coating has a slight lubricity, and stones are not likely to fall off in sheets when impacted, and it is wear-resistant and impact-resistant.
Different from the ordinary rubber chassis paint in the aftermarket, the original factory silicone-based chassis coating uses low-volatile and environmentally friendly silicone oil. The VOC content complies with the national automotive coating standards, and there is no odor release during high-temperature driving. The flexibility of the coating is suitable for the bumpy deformation of the chassis, and it will not crack or peel under cold and hot alternation. The protection period can reach the entire life cycle of the vehicle's use.
In 2026, the popularization of lightweight aluminum alloy chassis for new energy vehicles will occur. Aluminum alloys are more prone to filamentous corrosion. The silicone oil anti-corrosion coating can stably combine with the aluminum substrate and meet the requirements of lightweight body protection. Domestic silicone oil raw material enterprises have developed special high-adhesion modified silicone oil for chassis painting, and have been equipped with multiple new energy vehicle chassis painting production lines. The market growth rate continues to rise.
