Common Coatings Used for Fabric Structures

Shelter System

Fabric structures have grown in popularity because of the many benefits they offer. Perhaps their most significant advantage is that they are movable. They likewise use less material and are lightweight.

A fabric structure is often coated to last a long and have a better appearance. Only the exterior is coated, as it is the part that is exposed to harsh weather conditions. DomeShelter Australia cites some of the most popular top coatings.

PVF Film Lamination

This coating is made up of Tedlar, which is also known as polyvinyl fluoride. The procedure for the application of the coating involves laminating the film layer to PVC fabric at the point of manufacturing. PVF film helps the fabric withstand weather elements and chemical agents. This makes the coating suitable for fabric structures used in desert regions, coastal areas, and industrialised towns.

Acrylic Top-Coating

This is perhaps the most popular top coating because it is budget friendly. The coating resulting from using acrylic is often thin due to its spray-on application. Materials coated with this type of coating are easy to fabricate and resistant to sun damage. Most acrylic-coated fabric structures are aesthetically pleasing because the coating gives the fabric a glossy finish.

PVDF Top Coating

PVDF is a mixture of carbon, hydrogen, and fluorine. This type of coating is better than an acrylic coating, as it provides higher resistance to UV degradation and prevents chemical damage. Fabric structures coated with PVDF also keep their colour for an extended period. Its application process involves chemically grafting the PVDF to the PVC.

Fabric structures with the above coatings can last approximately 10-20 years. Whilst the coatings do increase the cost of building a fabric structure, the benefit in terms of durability makes the price worth it. Lastly, coatings enhance the cleaning properties of the fabric.
