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.
It can be used together with other coating agents, e.g. ethyl cellulose. Cellulose acetate phthalate is commonly plasticized with diethyl phthalate , a hydrophobic compound, or triethyl citrate , a hydrophilic compound; other compatible plasticizers are various phthalates, triacetin , dibutyl tartrate , glycerol , propylene glycol ...
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.

Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...

The coatings groups consist of the following business units: [46] [47] Decorative Paints; Marine and Protective Coatings; Automotive and Specialty Coatings; Industrial ...
Modern tablet coatings [13] are polymer and polysaccharide based, with plasticizers and pigments included. Tablet coatings must be stable and strong enough to survive the handling of the tablet, must not make tablets stick together during the coating process, and must follow the fine contours of embossed characters or logos on tablets.
Binders are the film forming component of a paint as it dries and affects the durability, gloss, and flexibility of the coating. Polyurethanes, polyesters, and acrylics are all examples of common binders. The solvent is the medium in which all other components of the paint are dissolved and evaporates away as the paint dries and cures. The ...
