News / FAQ

A: KISHO Glass Coating products are formulated with scientifically balanced silicon compounds. Depending on the product type, the total silicon content can range from 85% to 95%.

A: According to our testing results in Japan, the coating reaches 6H hardness. In Japan, 6H is the highest measurable standard under the local testing method. However, some overseas customers have reported results of up to 9H based on their own testing standards and equipment. Different testing methods may produce different results.

A: Polysiloxane and polysilazane products are classified as chemical products, and their flash points vary depending on the formulation. Generally, products with larger molecular structures are more stable and less flammable.

A: Under normal conditions, the coating will not fail completely within such a short period. However, gloss, hydrophobic performance, and slickness may gradually decrease depending on environmental conditions, washing frequency, storage conditions, and maintenance habits.

A: Coating durability is affected by several important factors:
1. Vehicle storage conditions
Vehicles parked outdoors for long periods are exposed to UV rays, rain, snow, and contamination, which can reduce durability. Vehicles stored indoors generally maintain coating performance much longer.
2. Vehicle paint condition
New vehicles usually achieve better coating durability compared to older vehicles with aged or damaged paint surfaces.
3. Environmental conditions
Climate, temperature, humidity, snow, rain, and UV exposure all influence coating performance. For example, vehicles in milder climates may maintain coating performance longer than vehicles exposed to harsh environmental conditions.
Horizontal surfaces such as the hood, roof, and trunk are more directly exposed to sunlight and contamination, so their durability may decrease faster compared to vertical panels.

A: Some customers perform direct adhesion tests by dripping the product onto a surface. However, this does not reflect the correct application method or actual product performance.
Ceramic coating products are designed to be evenly applied and leveled across the surface. Proper bonding occurs after spreading and curing on the paint surface. Once fully cured, the coating forms a durable protective layer that is difficult to remove without polishing.

A: Yes. Some KISHO coating products may crystallize when dropped into water. Warm or hot water can accelerate the crystallization process.

A: Product pricing depends on formulation quality, raw materials, manufacturing standards, and performance stability. As a manufacturer, we supply products directly, allowing customers to receive competitive pricing without additional dealer markups.
Our goal is to establish long-term partnerships and provide stable, professional coating solutions for distributors and detailing businesses worldwide.

A: We offer two types of coating liquids: transparent and light yellow. The light yellow formula is one of our key products and contains special gloss-enhancing ingredients designed to improve paint appearance and depth.
After application and wipe-off, the coating becomes completely transparent and will not change the original paint color.

A: Different coating products use different silicon compounds and solvent systems, so the viscosity may vary depending on the formulation.
Lower-viscosity coatings are generally easier to apply and wipe off, making installation more efficient and user-friendly. Higher-viscosity products may require more application experience and additional effort during leveling and wipe-off.

A: Under normal conditions, the application process for one vehicle can usually be completed within approximately 30 minutes.
However, installation time may vary depending on the technician's experience, application environment, and familiarity with the product.

A: The recommended storage temperature is between 4°C and 20°C. When stored in a cool, dry place away from direct sunlight, the shelf life is approximately 2 year.
After opening, please seal the bottle tightly and store it in a cool environment.

A: One of the key properties of ceramic coating products is resistance to environmental contamination, acid rain, and chemical exposure.
The coating forms a protective layer on the paint surface, helping reduce damage caused by environmental conditions.
Some businesses perform extreme acid and alkali tests for promotional purposes. However, we do not recommend destructive testing methods, as they do not accurately reflect real-world usage or long-term coating performance.

A: Although ceramic coatings provide long-term protection, regular maintenance is recommended to help preserve gloss, hydrophobic performance, slickness, and overall coating condition.
We generally recommend maintenance every 3–6 months, depending on environmental conditions and vehicle usage.
Before applying maintenance products, contaminants such as iron particles and dirt should be properly removed from the coating surface. Avoid using aggressive clay treatment directly on the coated surface, as improper use may reduce coating performance.
During rainy seasons, applying maintenance products can help reduce the risk of water spotting and environmental contamination.

A: Under baking booth conditions at approximately 60°C, the coating curing process generally takes around 2 hours.

A: Durability depends on formulation, application quality, environment, and maintenance. Proper maintenance helps extend coating performance.

A: Ceramic coating helps reduce minor swirl marks and improves surface protection, but it does not make the vehicle fully scratch-proof.

A: Yes. Proper coating products and application methods are important to maintain the original matte appearance.

A: Hydrophobic performance helps water slide off more easily, reducing water retention and making maintenance easier.

A: No. Ceramic coating helps reduce contamination adhesion, but regular washing and maintenance are still necessary.

A: Maintenance products help preserve slickness, hydrophobic performance, and overall coating condition over time.

A: Yes. Ceramic coating can enhance paint reflection, depth, and overall appearance.

A: High spots are usually caused by excessive product application or improper leveling during installation.

A: Water behavior depends on formulation, surface condition, and coating maintenance.

A: Yes. Some professional coating systems support layering for enhanced performance and durability.

A: Wheels are exposed to brake dust, heat, and contamination. Wheel coating helps simplify cleaning and improve protection.

A: Window coating improves water repellency and visibility during rainy conditions.

A: Yes. Temperature and humidity can influence flashing time and application stability.

A: Ceramic coating creates a smoother surface layer, improving slickness and reducing friction.

A: Surface preparation, environment, maintenance, and product formulation all affect durability.

A: Yes. Proper paint correction and preparation can improve coating performance on older vehicles.

A: Surface contamination or improper preparation can affect bonding and final coating performance.

A: Curing time is the period needed for the coating to stabilize and reach optimal performance after application.

A: Ceramic coating helps reduce the impact of UV exposure and environmental contamination.

A: In ceramic coating production, formulation quality, raw materials, and manufacturing consistency all directly affect product performance.
Extremely low-cost products may use lower-grade raw materials or simplified formulations, which can lead to:
• Inconsistent performance
• Reduced durability
• Unstable hydrophobic behavior
• Application difficulties
• Batch inconsistency
For professional detailers and distributors, stable quality and long-term reliability are often more important than simply choosing the lowest price.
Consistent products help create consistent results.

A: New vehicles usually have cleaner and less damaged paint surfaces, allowing the coating to bond more effectively.

A: Yes. Proper maintenance products can help refresh water behavior and surface condition.
