Abstract
A liquid film coating process is provided in which a curtain (5) from at least one coating fluid (1) is poured on an object (10) being conveyed at right angles to the curtain (5). A fluid coating (6) is formed on the object (10) as a result. A mixture of a coating material and an organic carrier liquid, which has a surface tension of at most 40 mN/m, is used as the coating fluid (1). The fluid coating (6) is solidified to form the final coating. To solidify the fluid coating either the organic liquid is removed from the fluid coating formed from the mixture on the object by evaporation or a liquid that can be polymerized by heating is used as the organic liquid in order to solidify the fluid coating formed on the object by polymerizing the organic liquid.
Claims20
A liquid film coating process, comprising:
- a) forming a curtain of at least one coating fluid to pour the fluid on an object, the object being conveyed at right angles to the curtain;
- and
- b) forming a fluid coating on the object as the fluid curtain is poured on the object being conveyed;
- c) using an organic liquid as the coating fluid that can be solidified on the object or using a mixture of a coating material and an organic liquid as the coating fluid that can be solidified on the object;
- d) wherein the organic liquid has a surface tension of at most 40 mN/M;
- and
- e) solidifying the fluid coating.
A liquid film coating process comprising the steps of:
- forming a curtain of at least one coating fluid;
- disposing the curtain to pour the fluid on an object;
- during the pouring moving the object under the curtain to form a fluid coating on the object as the fluid curtain is poured on the object being conveyed;
- using an organic liquid as the coating fluid that can be solidified on the object or using a mixture of a coating material and an organic liquid to provide the coating fluid that can be solidified on the object wherein the organic liquid with a surface tension of at most 40 mN/M;
- and
- solidifying the fluid coating.
