How many types of car chassis armor are there?
2 Answers
There are four types of car chassis armor, namely: 1. Asphalt-based chassis anti-rust glue; 2. Oil-based solvent chassis anti-rust glue; 3. Water-soluble chassis anti-rust glue; 4. Composite polymer resin paint. Car chassis armor is a high-tech adhesive rubber asphalt coating used for anti-collision, anti-rust, and sound insulation of the car chassis. The functional characteristics of car chassis armor are: 1. Chassis anti-corrosion; 2. Preventing stone impacts on the bottom plate during driving; 3. Eliminating resonance generated by the engine, wheels, and bottom plate, providing shock absorption; 4. Reducing noise generated between the vehicle and the ground during driving; 5. Preventing underbody scraping and reducing the degree of damage to the chassis.
There are quite a few types of automotive undercoating. After driving for over a decade, I've found the main ones to be asphalt, rubber, water-based, and polyurea. Asphalt coating is the most common - inexpensive and quick to install with decent rustproofing, though it may soften in summer heat and has a strong odor making it less eco-friendly. Rubber-based coatings incorporate elastic materials, providing exceptional noise reduction especially noticeable during highway driving for a quieter, more comfortable ride with comprehensive protection. Water-based undercoating uses water as its base - non-toxic, fast-drying, and environmentally friendly, making it the top health-conscious choice for family vehicles. Polyurea is the premium option - extremely impact-resistant with over a decade of durability, though significantly more expensive, ideal for off-roading or challenging terrain. Beyond these, some hybrid or specialized rustproof coatings exist. When selecting, consider your vehicle's usage: opt for economical options for city commuting, choose high-pressure-resistant coatings for rural rough roads, and maintain the coating regularly to preserve integrity and save on repair costs - practical and durable.
