Due to the normally high solids content of UV coating/varnish the surface of the cured film can be extremely reflective and glossy. 80 lb text and heavier weights of paper can be UV coated, however, cover weights are preferred. UV can be applied on spot locations of the paper or by flooding the page.
Marine canvas is typically used to protect materials susceptible to UV damage like varnished wood, non-UV resistant plastics, and outdoor stored sails. Other boat specific uses include hatch covers for interior sun protection and winch covers for protection from deterioration and fouling due to seawater, rain, and dirt exposure. [5]
The UVB range is 280 to 320 nanometers, and the UVA range is 320 to 400. Ecamsule protects against UV wavelengths in the 290–400 nanometer range, with peak protection at 345 nm. [4] [5] Because ecamsule does not cover the entire UV spectrum, it should be combined with other active sunscreen agents to ensure broad-spectrum UV protection ...
This reduces the absorption of UV rays by the polymer matrix and hence reduces the rate of weathering. Phenolic benzotriazoles (e.g. UV-360, UV-328) and hydroxyphenyl-triazines (e.g. Bemotrizinol) are used to stabilise polycarbonates and acrylics, [25] oxanilides are used for polyamides and polyurethanes, while benzophenones are used for PVC.
UV-absorbing compounds are used not only in sunscreen, but also in other personal care products, such as lipstick, shampoo, hair spray, body wash, toilet soap, and insect repellent. [2] Chemical filters protect against UV radiation by absorbing, reflecting, or scattering it.

A relatively new rating designation for sun protective textiles and clothing is UPF (ultraviolet protection factor), which represents the ratio of sunburn-causing UV measured without and with the protection of the fabric. For example, a fabric rated UPF 30 means that, if 30 units of UV fall on the fabric, only 1 unit will pass through to the skin.
