Aerosol filling technology for automobiles
The global car ownership has exceeded 1.46 billion (Statista), with an aftermarket size of US$1.8 trillion. Aerosols, with their advantages of “precise spraying and instant use,” cover 85% of car care scenarios—from engine cleaning to air conditioning sterilization—covering more than 85% of car care scenarios, with a global annual growth rate of 5.3% (2023-2029 forecast).
As a Filling Equipment manufacturer, we have witnessed the industry's technological upgrades:
- Anti-settling filling → Uniform distribution of solid-containing formulations
- Ultra-strong anti-corrosion system → Resists corrosion from strong solvents
- Low-temperature preservation process → Protects fragrance activity
These innovative processes are driving the global automotive care industry toward greater efficiency and sustainability.
1.Aerosol cleaners for automobiles
(1)Surface cleaning
| Products | Key ingredients | Filling Process Essentials |
| Tire/Wheel Cleaner | Alkaline surfactant | Anti-corrosive filling head (pH>10) |
| Tar/Insect Stain Cleaner | Kerosene solvent + Emulsifier | Explosion-proof filling (flash point <23°C) |
| Windshield Cleaner | Ethanol base + antifreeze agent | Low-temperature, anti-volatile filling (5°C) |
| Foam Cleaner (Car Exterior/Interior) | Anionic surfactant | Steady-pressure filling to prevent premature foaming |
(2)Internal cleaning of the system
| Products | Technical characteristics | Filling Challenges |
| Carburetor/Throttle Cleaner | Chlorinated solvents (strong corrosive) | Hastelloy lines + nitrogen seals |
| Three-way Catalytic/Oxygen Sensor Cleaner | Weakly acidic formulations (pH=3-5) | Teflon coated for corrosion protection |
| Air Conditioning System Sanitizer | Quaternary ammonium salts + ejectants | Cold filling (8°C to preserve activity) |
2.Maintenance and protection aerosols
(1)Surface protection
| Products | Functional Core | Filling process |
| Surface Wax/Leather Conditioner | Silicone emulsions | High viscosity filling (screw pump) |
| Chassis Armor/Rust Spray | Asphalt/rubber granules | Anti-settling agitation + ceramic valve |
| Window Seal Protector | Silicone lubricants | Oxygen-free filling (oxygen content <0.1%) |
(2)Internal maintenance of the system
| Products | Application Scenarios | Special process |
| Line Protector | Engine Circuitry | High-temperature-resistant filling (viscosity reduction at 60°C) |
| Tire Self-Replenishing Fluid | Sealant + Fiber Granules | Solid-formula-containing anti-clogging nozzle |
| Refrigerant/Rapid Coolant | Air Conditioning System | High-pressure filling (1.2MPa) |
3.Repair of spray aerosols
| Type | Representative Products | Filling key technology |
| Paint Restoration | Scratch Repair Paint / Coating Spray | Nano color paste anti-settling |
| Corrosion Protection Primer | Rust Preventive Primer / Weld Protection Paint | Aluminum powder anti-settling filling |
| Interior Refinishing | Interior Repair Paint | Precise color mixing filling system |
4.Environmentally regulated aerosols
| Functions | Product Examples | Ingredient Characteristics |
| Defogging and anti-icing | Glass Antifogger/Ice Melt | Ethanol-based (flammable and explosion-proof) |
| Air purification | Deodorizer/Car Fragrance | Fragrance Cold Fill (4°C) |
| Water and dirt repellent | Wheel Nano Coating | Fluorocarbon Resin (high viscosity) |
5.Special function aerosols
| Application Scenarios | Product Examples | Filling Core Requirements |
| Safety Inspection | Leak Detector (Fluorescent Tracer) | Filling under light + low temperature storage |
| Emergency Repair | Tire Inflator and Repair Fluid | Anti-settling of fiber particles |
| Mechanical Maintenance | Circuit Dehumidifier Spray / Noise Reducing Spray | Purified filling of insulating components |
