MetaShieldUV is a thin, transparent, and durable coating that contains unique nanoparticles that block both UV-A and UV-B wavelengths. The nano-engineered formula drastically reduces the harmful effects of UV in both land-based and interstellar applications. This coating is compatible with a wide range of materials and can be applied in as little as 20 minutes, and within the current manufacturing process with little disruption. Since it is made with silica, the same base material as glass, it has many of advantages of glass, such as higher resistance to temperature, UV degradation, and weather conditions.
Plastics are finding increasing use in manufactured parts in automobiles and aircrafts. While plastics offer several excellent properties including light weight, formability, and low cost, plastics also have significant disadvantages such as damage from the sun’s ultraviolet(UV) rays. UV degradation affects plastics, wood, dyes, and many other materials that when exposed to sunlight suffer from discoloration, fading, cracking, loss of strength, or disintegration. The effects of attack increases with exposure time and sunlight intensity.
Window and automobile glass absorbs some harmful UV, but not nearly enough protection against photoaging – UV rays’ skin-aging effect.
UV-B causes sunburns and ages spots. UV-A causes skin to sag and develop wrinkles, and worse yet, lead to harmful diseases such as melanoma. When applied to glass, MetaShieldUV can block many of these harmful rays.
The $8+ billion market for UV protection is currently dominated by relatively thick laminates and inferior polymer-based coatings. These products have significant downfalls. In the case of terrestrial applications, such coatings are often labelled for indoor use only and are incapable of protecting materials outdoors where they are most susceptible to UV degradation. The cover glass sheets currently used to block UV offer good protection but relatively thick and heavy. This is a significant disadvantage for sending structures into space where every single bit of mass costs a premium.
