Abstract:
PHOTOPOLYMERIZABLE FILM-FORMING POLYMER COATINGS ARE CURED BY SUBJECTING THEM TO LIGHT WAVES WITHIN THE RANGE OF 1850 TO 4000 ANGSTROMS IN THE PRESENCE OF AN ELECTROSTATIC FIELD.
Abstract:
Provided herein is a method of curing a waterborne coating comprising: (1) preparing a waterborne coating comprising: (a) at least one photoinitiator and (b) at least one pigment, wherein the pigment volume concentration of the waterborne coating is 2.0% to 68.7%; (2) curing the waterborne coating using UV radiation; and (3) curing the waterborne coating using EB. The method may further comprise the step of drying the waterborne coating prior to curing the waterborne coating using UV radiation. Also described is a waterborne coating prepared from the method described herein and an article to which the waterborne coating is applied.
Abstract:
An improved inside of can curing technology is provided. One implementation uses narrowband, semiconductor produced infrared energy which is focused into the inside of the can to affect a very high-speed curing result and will directly impact the coating covering the inside walls of the can to rapidly cure the coating. Detempering and annealing of the aluminum can body does not have time to occur, thus leaving a stronger can with the same amount of aluminum or a can of the same strength but with less aluminum. It is also possible to eliminate the natural gas fueled oven that is the current standard and replace it with a completely hydrocarbon-free curing alternative that has superior performance. This high powered radiant, narrowband energy will be digitally controlled to introduce only the needed heat and to not overheat the can.
Abstract:
An apparatus and to a method for treating layers using a plasma zone sealed from the outer atmospheric pressure are provided. The apparatus and method include a plasma reactor including a substrate carrier in form of a container receiving means, and a closing element that is joined with the substrate carrier by means of a lifting device.
Abstract:
The present invention discloses methods for producing an optically clear, biocompatible and durable hydrophilic coating for contact lenses comprising the steps of first applying a polymer coating on the contact lenses by plasma polymerization of monomers containing ethylene glycol groups, followed by incubating the coated contact lenses at an elevated temperature to remove the volatile residual monomers trapped inside the coating. Advantageously, such methods produce an optically clear, biocompatible and durable hydrophilic surface for contact lenses in a dry, solvent-free process.
Abstract:
To manufacture a coating for an article for a semiconductor processing chamber, the coating is applied to the article by a method including applying a sol-gel coating of Y2O3 over the article, and curing the sol-gel coating on the article by heating the article with the sol-gel coating and exposing the article with the sol-gel coating to plasma in a semiconductor manufacturing chamber.
