The invention relates to a coating composition comprising (i) a supporting medium, and (ii) a plurality of cellulose particles, having an average dry particle size of less than 10 .mu.m, dispersed in the supporting medium, excluding aqueous coating compositions adapted for application to paper. The invention also relates to a coating composition comprising (i) a supporting medium, and (ii) a plurality of cellulose particles, having an average dry particle size of less than 10 .mu.m, dispersed in...

The invention provides apparatus for electrostatically coating a pharmaceutical tablet core with powdered coating material. The apparatus comprises a first rotary drum (12) on which a core is held in electrical isolation from its surroundings but at a potential differecne to earth by an electrode which contacts the core. The core is carried past a coating station B at which particles of powder having an opposite potential difference to earth are held in a tray (18). The surface of the drum is he...

This invention concerns an epoxy coating for use as a non-skid surface for applications such as the deck of an aircraft carrier. The epoxy coating can be formulated from (a) an amine curing agent, (b) an epoxide-containing toughening agent such as a polysulfide and/or a polythioether, (c) an epoxy resin, (d) a rubber toughening agent, and (e) an optional fire retardant, a glass fiber thixotrope and impact toughening agent, an optional pigment, an optional corrosion inhibitor, an optional moistur...

A stent comprising a coating layer is disclosed. The coating layer has a hydrophobic component and a hydrophilic component, wherein a region of the coating layer on or about the outermost surface of the coating layer has a higher content or concentration of the hydrophilic component than the hydrophobic component.

There is provided a coating device which can quickly cope with a change in size of a container. A pair of coating belts (annular belts) (11, 15) are arranged on two sides of a conveyor (10). The coating belt (15) is rotated at a high speed while the coating belt (11) is rotated at a low speed. A container (bottle) (1) on the conveyor (10) is coated while being rotated. When the size of the container (1) is to be changed, a pressing roller (57) is moved by an adjusting mechanism (50) in accordanc...
