Frequently Asked Questions

CryoSkin is a radiative cooling enhanced self-adhering vinyl. It cools outdoor surfaces by around 15°F without electricity. It can be custom cut or purchased by the square foot for DIY projects. CryoSkin is also available in larger quantities for industrial applications such as vehicle wraps and commercial electronics.

Current testing indicates that CryoSkin should last many years if left alone. CryoSkin is inherently weatherproof, and its performance remains consistent even with dust and rain. CryoSkin cannot be cleaned, and it is damaged by oils and abrasion. Avoid car washes, pressure washers, or any other abrasive cleaning methods, and only clean with gently sprayed water. Do not apply overcoats or sprays. CryoSkin can be submerged, although the radiative cooling effect does not work underwater.

Radiative cooling reflects incoming heat and emits accumulated heat back into space. By minimizing sunlight absorption and maximizing heat emission, the material cools below ambient air.

• Flat orientation.
• Low humidity.
• Clear line of sight to the sky.
• Elevated temperatures.
• Best during solar noon.

Apply on parts facing the sky, such as the roof. Avoid wrapping perpendicular surfaces.

CryoTile is a MagSafe accessory for MagSafe compatible iPhones. It uses radiative cooling technology to minimize overheating. Under optimal conditions, it can be up to 15°F cooler than ambient air. The core radiative cooling material is encased in a durable, waterproof ABS and Polycarbonate shell. CryoTile is still under development.

CryoSkin is an automotive vinyl with a pressure sensitive adhesive built in.
Always handle CryoSkin with gloves or freshly cleaned and dry hands.
Make sure your work environment and the destination surface are cleaned as well to prevent contamination.
Never scrape the surface of CryoSkin with a tool.
We recommend using the back of the hand to push out bubbles since there is less friction and skin oils.
Stick along a straight edge about an inch wide then pull the protective wax paper evenly along the designated surface, like applying a band-aid.
You may use a heat gun.
Push out any large bubbles gently afterwards.
Small bubbles will escape over time due to the unique micro-channels in the adhesive.

Cryo X products only come in white due to the nature of radiative cooling materials and physics. In order to reduce the amount of energy absorbed, radiative cooling materials need to reflect in a wide spectrum of energy. This wide spectrum reflectivity is not just in the visible spectrum, but also infrared. Because of this, Cryo products appear a brilliant white. Adding any color would mean that it would absorb energy in a portion of the visible spectrum, decreasing reflectivity and performance.

Cryo products are not insulators. Think of an insulator as a brick wall for heat. It prevents heat from coming in, but also keeps it from going out. Cryo X Co’s radiative cooling materials act as a one way door for heat, preventing heat from coming in while venting any heat it absorbs to space. This is why it’s important to apply radiative cooling materials to non-insulating surfaces so that you can remove as much heat as possible from the object you are trying to cool.

No, radiative cooling products do not work behind other objects. Cryo products require a clear view of the blue to perform. Radiative cooling materials work in the infrared spectrum, meaning that objects that appear transparent to us are often not transparent in the infrared. There are a few very niche scientific materials that are compatible, but their price and availability make their implementation prohibitive. For this reason, we designed Cryo products to be durable and resilient on their own.

Water. Cryo products are designed to be self cleaning when exposed to rain, so if you would like to clean it yourself we recommend spraying with a hose. Do not ever use chemicals or abrasive cleaning methods, and pressure wash with at least 6 inches-1 foot away from the surface, be wary about the strength of any pressure washers. If you are to take it through a carwash, request that they turn off the top scrubbers and not use any protective coating chemicals. Remember that its effectiveness is a function of the total surface area still operational. Unless the paint is completely removed or disabled, it will still work.

CryoSkin is applied like a band aid, or the same way as any other automotive vinyl. It is even heat gun compatible. Always have clean hands or gloves, and make sure when working with the vinyl to do so on a freshly cleaned surface. Avoid dirt, dust, and grime contamination. Apply to a freshly cleaned surface as well. Use the back of your hand to push out bubbles gently to avoid scraping the surface. CryoSkin features advanced adhesive technologies that push out minor bubbles naturally within a few days, and a pressure sensitive adhesive that allows you to remove and adjust as much as needed within the first week of application. Note that after the first week the radiative cooling technology fuses to the vinyl and we cannot guarantee it will survive removal. The vinyl is surface safe for most surfaces, but consult with the 3M website for details on the 2080 series adhesive technologies.

CryoPaint is applied like any standard spray paint, which means that it has all the same recommendations. Apply 2-4 dry coats on a flat surface to avoid dripping or clumping. (Dry coat means that the nozzle is at least 1.5-2 feet away from the target surface, allowing the paint to “dry” faster upon impact.) Allow 30-45 minutes between coats for the surface to dry. Apply to a prepared surface that has been cleaned and ensure that it will have surface grip for the paint. You may have to sand the surface if it is particularly glossy. Apply outdoors with plenty of ventilation or with appropriate respiratory protection for high VOC paint.

Cryo products are applied to any surface that faces the sky. We recommend it be a flat surface with a clear view of the blue. The further you tilt it away from the sky, the lower its performance will be.

Cryo products are safe in their dried form, however we ask that you treat it like any other paint. Do not eat it, wash your hands after handling, and use common sense. CryoSkin comes dried, so it is safe to handle out of the box. CryoPaint is in its liquid form, so treat like any other high-VOC paint. Use adequate skin, eye, and breathing protection and handle with care. Refer to our safety disclaimer here
