Aqueous film coating is the most common film coating method currently used. [1] This type of film coating uses water to aid in the film coating process instead of organic solvents. [ 1 ] The result is a safer means of film coating, as it avoids the toxic and flammable properties of organic solvents.
Low-expansion foams, such as aqueous film forming foams (AFFFs), have an expansion ratio of less than 20, are low-viscosity, mobile, and can quickly cover large areas. Medium-expansion foams have an expansion ratio of 20–200.
Ethyl cellulose is commonly used as a coating material for tablets and capsules, as it provides a protective barrier that prevents the active ingredients from being released too quickly in the digestive system. [2] EC is also used as a binder, thickener, and stabilizer in a variety of food, cosmetic, and pharmaceutical products.
Modern automobile paint is applied in several layers, with a total thickness of around 100 μm (0.1mm). Paint application requires preparation and primer steps to ensure proper application. A basecoat is applied after the primer paint is applied. Following this, a clearcoat of paint may be applied that forms a glossy and transparent coating.

Xylan is generally used to reduce friction, improve wear resistance, and for non-stick applications. Additionally, it can be used to protect a metal from corrosion.The most commonly known application is in non-stick cookware but Xylan coatings have also been used extensively in the automotive industry and for corrosion protection in the oil and gas industry.
Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
