What is the difference between automotive paint crystal coating and film coating?
1 Answers
Automotive paint crystal coating and film coating differ in the following aspects: 1. Different composition: The main components of film coating are generally organic and inorganic materials, while crystal coating primarily consists of silicon dioxide inorganic materials. 2. Different hardness: Crystal coating forms a crystalline structure, making it harder than film coating. 3. Different brightness: Crystal coating exhibits higher diamond-like crystal brightness. 4. Different durability: Crystal coating, being an inorganic crystalline material, offers greater stability and longevity. Additional information: The advantages of automotive crystal coating include: 1. Scratch resistance: Diamond crystal hardness reaches 6H, compared to the 2H hardness of standard car paint, effectively preventing most minor scratches. It also features elastic recovery properties, protecting the vehicle from daily minor scratches and reducing paint scratches by over 70% compared to regular film coatings. When external forces exceed the elastic protection range of the crystal, it typically only leaves scratches on the crystal layer without damaging the underlying paint. 2. Corrosion resistance: The ultra-fine nano-crystalline layer of diamond crystal isolates the paint surface from external elements, effectively preventing oxidation and resisting corrosion from bird droppings, insect residues, acid rain, etc.
