Q: Why is the piece for motorcycle helmet so narrow? Is it big enough?
A: Most of the motorcycle helmet visors are non-cylindrical, which means that they are curved both horizontally and vertically. We conducted many surveys and personally tried cutting the superhydrophobic film into various shapes to meet the three major requirements: wide visual field, good adhesion without curling, adaptability" The film may look a bit narrow, but the visor is close to the eye like glasses. Therefore, most of the visual field can be sufficiently covered.
If you really want your visor to be fully covered, you can apply the A5 model if your helmet visor is cylindrical. We guarantee it will be large enough.
Q: Which motorcycle helmet visors fit the CA160 film? Are there any restrictions?
A: Unidirectional curved cylindrical visors definitely fit , and common bidirectional curved shield visors can also use the product . We have tested on 90% of the visors on the market, and they all can fit ! Basically, as long as the curvature of the helmet visor is not too large, there should be no problem with application. If you are not sure which type of visor your helmet visor belongs to, you can refer to the picture below:
Q: Can the high-adhesive version be repeatedly peeled off?
A: Only the low-adhesive version can be peeled off repeatedly. After a period of time, the high-adhesive version cannot be peeled off intact. In other words, although the high-adhesive version can be peeled off, the film surface is difficult to avoid being damaged during the process of peeling, so it is not recommended to peel.
Q: What should I do if CA160 film cannot be flattened and fit perfectly with the visor?
A: Excluding the situation that the helmet visor was not properly cleaned and dried before covering by the film, if the film is still not well attached, you can use a hairdryer to heat the detached area while using a scraper to smooth it out. After repeating this process several times, the detachment should be improved. If the hairdryer still cannot fix the problem, you can use small scissors to cut a slit from the edge inward at the detached area, which will help the film adhere better.
Q. What is the difference between CA160 and other similar products?
A: According to our research, the core technology of other retail rainproof films and waterproof films are hydrophilic. Hydrophilic films require water droplets to form a water film on the surface before you get a clear vision, so they are basically ineffective when drizzling. In addition, water films can cause light distortion, resulting in image distortion and affecting vision. Finally, because water adheres to hydrophilic films, they are prone to water and oil stains. Without regular cleaning, they can easily become ineffective.
None of these issues occur with the hydrophobic CA160. But why does everyone make hydrophilic films instead of hydrophobic ones? Because hydrophilic films are easy to make and inexpensive. And chemical Hydrophobic films have limited effects while nano-structured hydrophobic films have high technical and cost thresholds. This is why CA160 is so rare. It is the world's first physically superhydrophobic transparent film, and its cost has been reduced to be mass produced , making it available to benefit society.
Q. Is it really "permanently" effective? What should I do if it fails?
A: CA160 achieves physical hydrophobicity through "nano-needle structures", rather than chemical hydrophobicity. As long as the structure is not damaged, it is effective. Therefore, strictly speaking, CA160 has no expiration date and can be stored for 20-30 years without losing effectiveness. However, on the other hand, once it is used and exposed to wind, sun, and rain, the nano-structure will inevitably accumulate damage that is barely visible to the naked eyes. Based on our experimental results and consumer tracking, if used for commuting every day, a piece of CA160 can last for about 8-16 months, and cannot be continuously used permanently! In addition to damage accumulated over long-term using, if CA160 accidentally comes into contact with oily substances, it will also fail temporarily. Therefore, when you find that your CA160 suddenly fails, first recall whether the usage time has reached the normal lifespan. If not, check for visible scratches or abrasions. If there are none, it is likely that it has come into contact with oil stains. At this time, you can use diluted dishwashing liquid or alcohol (75% is enough, 95% is better) to rinse it, and then gently absorb the moisture with a tissue, which can restore CA160 to its original effectiveness! (For detailed cleaning methods, please see the next question.)
Q. How to clean if it gets dirty? What can be used to clean it?
A: CA160 has a self-cleaning function, which is like a lotus leaf that stays clean even when it emerges from mud. It is actually difficult for dirt to stick to the surface. However, if it accidentally comes into contact with oily substances or a layer of thin scale builds up from long-term use, the hydrophobicity will become ineffective. For different situations of ineffectiveness, we have the following recommended cleaning methods:
1. During the installation process or within the first month of use, if it loses its effectiveness due to contact with oily substances (such as skin or food): >> Spray it with alcohol (75% is sufficient, 95% is better), then gently wipe it clean with a piece of tissue paper. It will regain its effectiveness. If there is no alcohol available, you can use diluted dishwashing detergent instead, then rinse it with clean water.
2. If it has been used for more than a month, and you feel that it has lost its effectiveness and the surface appears to be slightly dirty: >> Due to long-term use, the surface may accumulate microscopic dust or scale crystals, which should not be wiped off with tissue paper! The wiping process may accidentally use the tiny particles as abrasive materials and damage the surface of the film, leading to irreversible ineffectiveness. We recommend using a large amount of alcohol (75% is sufficient, 95% is better) to spray the film surface and use a "rinsing" method to dissolve and remove the particles. After spraying the alcohol, let it sit for one minute, then spray it again. For the third time, after waiting for one minute, gently touch the film surface with tissue paper to absorb the remaining alcohol and moisture. Do not wipe it! After the alcohol and moisture are completely dried, you can spray water to check if the hydrophobicity has been restored. If not, repeat the alcohol rinsing process several times. According to experiments, it usually takes three to four times to slowly wash away the dirt accumulated over the years, without damaging the micro-needle structure of the film surface. This is currently the safest cleaning method.
Even if the dirt on the film surface does not affect the hydrophobicity, we recommend using the above alcohol rinsing method for maintenance, because scale and oil stains that have been present for too long can become very difficult to clean. If there are any water scale or oil stains that cannot be rinsed off, as long as they do not affect the hydrophobicity of other areas, they can be ignored and continue to be used. *Note: When using alcohol for cleaning, wait until it has completely evaporated and dried before the hydrophobicity can be restored If there is still some alcohol residue, the hydrophobicity will become ineffective.
Q: Is it scratch-resistant? What should I do if it is scratched by flying sand or gravel?
A: The scratch resistance of CA160 is almost the best on the market. It is not affected even when using a plastic scraper or nails to scrape it hard. It is resistant to friction or collision with plastic objects. According to the test results, CA160 attached to the rearview mirror and side glass of cars and motorcycles will not be damaged even after several months because it is not directly hit by wind and sand. As for those attached to the helmet visor, which faces wind directly, only a few extremely fine scratches or marks appear after three or four months, but they do not affect its function.
Q: Is there a film for the front windshield of a car?
A: No! The reason is simple, it is too expensive... This material is technologically advanced and expensive to produce, so it is recommended to use a windshield wiper for the car windshield.
Q: Can CA160 prevent fogging?
A: No, it cannot. Anti-fog sprays or films are hydrophilic, while CA160 is hydrophobic and cannot prevent fogging. Therefore, we provide a complimentary Zeiss Anti-fog Wipes for the inside of the helmet visor. This way, the outside is waterproof, and the inside is anti-fog, ensuring clear vision both inside and outside!
Q: Can I apply it on a swimming goggle?
A: No, you cannot! If CA160 is forced to soak in water for a long time, the nanofiber structure will start to absorb water and become slightly foggy and opaque.
