What type of coating is applied to protect the fabric from UV light?

The appropriate choice for protecting fabric from UV light is the finish coat. This type of coating is specifically designed to provide a protective layer that helps prevent degradation from ultraviolet radiation, which can cause the fabric to weaken and deteriorate over time. The finish coat includes UV-resistant properties, enhancing the longevity and performance of the fabric.

While primers serve as a preparatory layer to enhance adhesion and improve the binding of subsequent coatings, they do not offer the same level of protection against UV light. Enamel is typically used for its durability and aesthetic qualities but does not specifically protect against UV damage. Thinners, on the other hand, are solvents used to reduce the viscosity of paints and coatings but do not provide protective qualities on their own.

In summary, the finish coat is essential for creating a barrier against UV radiation, ensuring the fabric maintains its integrity and durability in outdoor conditions.
