摘要:
The present invention provides for an etch and mar resistant low VOC clear coating composition most suitable for use as a top clear coat in multi-layered OEM or refinish automotive coatings. The coating composition includes isocyanate, carbonate and melamine components. The isocyanate component includes an aliphatic polyisocyanate. The composition may be formulated as a two-pack or one-pack coating composition, wherein the isocyanate functionalities are blocked with a blocker such as a mono-alcohol.
摘要:
A low VOC clear coat composition which comprises an epoxy compound, a melamine component and an aliphatic polyisocyanate having an average of 2 to 6 isocyanate functionalities, and optionally contains a catalyst (e.g., organotin catalysts, acid catalysts and combinations); a polyhydroxyl functional compound (e.g., polycarbonate polyol); or other additives (e.g., light absorbers and light stabilizers). Also disclosed is an article coated with the clear coat composition, a process of making the composition, and a process of applying the composition to, for example, an automobile body.

摘要:
This invention relates to rapid curing coating compositions that are particularly useful for automotive OEM and refinish applications. The coating composition includes a binder component that contains a novel highly branched copolyester polyol, and a crosslinking component that contains conventional crosslinking agents, such as polyisocyanate and melamine. This invention is also directed to a process for producing coatings from the rapid curing coating compositions. These compositions are especially useful in providing for mar resistant and flexible coatings.
摘要:
A full-color electrophotographic apparatus of the present invention is configured such that a toner image is formed on an intermediate transfer member. The intermediate transfer member is heated to a temperature equal to or higher than the softening start temperature of resin contained in a liquid toner and equal to or lower than the withstand temperature of a photoconductor member. A carrier-removing roller to which bias can be applied abuts the intermediate transfer member so as to remove a carrier while packing softened toner by the force of an electric field induced by bias. In a transfer section for transfer to a printing medium, a backup roller presses the printing medium against the intermediate transfer member, and the toner image is transferred from the intermediate transfer member to the printing medium. Before being pressed against the toner image on the intermediate transfer member, the printing medium is heated. Bias is applied to the backup roller such that the toner image on the intermediate transfer is attracted toward the printing medium by the action of an electric field, thereby assisting transfer. By so doing, the intermediate transfer member does not need to undergo cooling before coming into contact with the photoconductor member, thereby avoiding occurrence of thermal damage to the photoconductor member.
摘要:
In the present invention, a toner image produced through a development process of supplying a liquid toner onto an image bearing body bearing an electrostatic latent image is transferred from the image bearing body onto an intermediate transfer body and then transferred from the intermediate transfer body onto a printing medium by use of a backup roller in a transfer-and-fixation zone. The printing medium is preheated to a temperature required for transfer and fixation before the printing medium reaches the transfer-and-fixation zone. No heating means is provided in the transfer-and-fixation zone, and the intermediate transfer body and the backup roller are pressed against each other at a high pressure ranging from 10 kg/cm2 to 60 kg/cm2. Alternatively, the intermediate transfer body is provided with heating means; resin for use in the liquid toner has a softening temperature not higher than withstand temperatures of members other than the intermediate transfer body such as a photosensitive drum; and the intermediate transfer body is heated to a temperature not lower than the softening temperature of the resin and not higher than the withstand temperatures of the other members.

摘要:
A jukebox apparatus including a magazine, a drive unit, a carriage for conveying a disk between the magazine and the drive unit, and a temporary storage unit movable between a transfer position in front of the drive unit and an escape position. The carriage has gripping arms, pinch rollers, and a pushing arm for transferring the disk. A control unit is provided to carry out a retry of transferring the disk by displacing the carriage when the disk is not transferred. The pushing time of the pushing arm can be changed by a retry of pushing the disk by the pushing arm. The temporary storage unit is normally monitored.
摘要:
A cleaning apparatus for a liquid-development electrophotographic apparatus in which, after a toner image formed on a surface of an intermediate transfer member by use of a liquid developer is transferred to a printing medium, the liquid developer remaining on the intermediate transfer is removed and collected. The cleaning apparatus includes a cleaning-liquid application device for applying a cleaning liquid to the intermediate transfer member which has transferred an image to the printing medium; a bias voltage application device for applying a bias voltage opposite in polarity to charged toner particles of the developer to the intermediate transfer member; and a collection device for removing the cleaning liquid which has been applied to and the residual developer which remains on the intermediate transfer member from the intermediate transfer member without transfer of an image to the printing medium, and collecting the removed cleaning liquid and residual developer.
摘要:
A rapid cure sprayable liquid coating composition containing a highly branched film-forming polyester polyol resin, a polyisocyanate crosslinking agent, and a volatile organic liquid carrier. Low molecular weight film-forming silane compounds are incorporated in the coating for better film properties, such as improved adhesion to commercially available windshield adhesives, and also for reduced spray viscosity, which leads to higher spray solids and lower volatile organic content. The coating composition can be used as a clearcoat over a pigmented basecoat to provide an attractive exterior automotive finish.
