Abstract:
A method of forming a digital embossing (17) on a surface (2) by bonding hard press particles (67) to a carrier (68). A liquid binder pattern (P) is applied on the carrier by a digital drop application head. Hard press particles (67) are applied on the carrier (68) and the binder pattern such that some hard press particles are bonded to the carrier (68) by the liquid pattern and non-bonded press particles (67) are removed. The carrier (68) with the bonded hard press particles (67) is pressed to the surface (2) and an embossing is formed when the carrier (68) with the hard press particles (67) is removed.

Abstract:
A primer coating composition for a metal substrate is described. The primer has a suitable binder and is characterized in that there is at least one semiconductor photocatalyst dispersed throughout the primer coating composition. A process of coating a metal substrate is also described. The invention extends to the use of a semiconductor photocatalyst as a top-coat to primer adhesion promoter or as a primer to top-coat delamination inhibitor in a primer coating composition.
Abstract:
Coating systems and processes are disclosed for uniformly coating objects. The system comprises a pre-treatment unit, a first processing unit, a first post-treatment unit and one or more coating apparatus each configured to engage an object and rotate the object around or about two or more axes. The coating apparatus used in the system can comprise a first, second and/or third gimbals connected to rotational mechanisms to allow rotation of the gimbals around or about first, second and/or third axis. An object holder is connected to the third gimbal. When an object is present in the object holder, it can be immersed in a coating solution to form a coated object. The coated object is then rotated around or about two or three axes which produces a multidirectional centrifugal force which causes the coating solution to spread evenly over the surface of the object to produce a uniform thin film.

Abstract:
It is an object, with regard to a configuration for forming a macromolecular layer on a surface of a base material of an artificial joint component, to achieve a size reduction, to accurately control ultraviolet irradiation intensity, to form a macromolecular layer having a uniform thickness, to suppress the influence of ultraviolet light on equipment and workers, and to make the occurrence of a malfunction unlikely. A film-producing device body forms a macromolecular layer in an inner surface of a base material of an artificial joint component, by means of photograft polymerization. The film-producing device body includes a plurality of ultraviolet LED elements and a work holder. On the work holder, solution containing macromolecular monomers is in contact with the inner surface of the base material. The ultraviolet LED elements emit ultraviolet light to a wider area than an area that each of the ultraviolet LED elements individually irradiates.
Abstract:
The present invention provides a silicon oxynitride film formation method capable of reducing energy cost, and also provides a substrate equipped with a silicon oxynitride film formed thereby. This method comprises the steps of: casting a film-formable coating composition containing a polysilazane compound on a substrate surface to form a coat; drying the coat to remove excess of the solvent therein; and then irradiating the dried coat with UV light at a temperature lower than 150° C.
