Abstract:
The invention relates to scratch-resistant coatings obtainable by radiative curing, by reaction of (meth)acrylates with mercapto groups, to processes for production thereof and to the use thereof.
Abstract:
Certain embodiments of the invention may include systems and methods curing a coated optical fiber. The method includes drawing the coated optical fiber through a gas chamber filled with a predetermined gas, drawing the fiber through a cure tube coupled to the gas chamber, and purging at least a portion of an inner surface of the cure tube with a purge gas as the coated optical fiber is drawn through the cure tube.
Abstract:
A process for producing polymeric films by applying a liquid composition onto a surface of a substrate under vacuum conditions in a vacuum chamber. The composition has a first component which is polymerizable or crosslinkable in the presence of a sufficient amount of an acid; and a cationic photoinitiator which generates an acid upon exposure to ultraviolet radiation, electron beam radiation or both to cause polymerizing or crosslinking of the first component. A gas which emits ultraviolet radiation upon exposure to electron beam radiation is introduced into the vacuum chamber. The composition and the gas are exposed to electron beam radiation to cause the cationic photoinitiator to generate an amount of an acid to cause polymerizing or crosslinking of the first component. The composition is exposed to both electron beam radiation and gas-generated ultraviolet radiation and cured.
Abstract:
The present provides a bondably coated metallic member comprising a metallic member having a low surface energy polymeric coating, said low surface energy polymeric coating having been surface activated on at least a portion thereof, and having on said surface-activated portion a bondable high surface energy polymeric coating. The present invention also provides a bondably-coated metallic pipe comprising metallic pipe having a low surface energy mainline polymeric coating thereon extending over the pipe except at a bare zone adjacent each end of the pipe that is free from said main-line coating; a portion of said mainline coating adjacent each bare zone having been surface activated and having on said surface activated portion a bondable high surface energy polymeric coating.
Abstract:
This application relates to omniphobic materials which are physically and chemically modified at their surface to create hierarchically structured materials with both nanoscale and microscale structures that provide the omniphobic properties. Methods of making such omniphobic surfaces with hierarchical structures and uses thereof, including as flexible films that repel contaminants are also disclosed in the application.
Abstract:
An ultraviolet curing apparatus having: a roller for guiding a film coated with a resin; a first nitrogen gas introduction port and a second nitrogen gas introduction port for introducing nitrogen gas; a UV irradiation portion for irradiating the film with ultraviolet rays from between the first nitrogen gas introduction port and the second nitrogen gas introduction port; an oxygen concentration meter for measuring an oxygen concentration between the film and the UV irradiation portion; an air introduction port for introducing air between the film and the UV irradiation portion; and a controller for controlling at least any one of: an amount of air introduced from the air introduction port, an amount of nitrogen gas introduced from the first nitrogen gas introduction port, and an amount of nitrogen gas introduced from the second nitrogen gas introduction port, so that the oxygen concentration is within a preset oxygen concentration set range.
Abstract:
A paint curing system is provided. The paint curing system includes a robot arm, a first light, a lamp panel, and a control module. The robot arm includes a first end and a second end that opposes the first end. The first light is disposed at the second end of the robot arm and is configured to cure paint on a first panel of a vehicle. The lamp panel is positioned adjacent to the vehicle and includes a second light that is configured to cure paint on a second panel of the vehicle. The control module configured to actuate the robot arm and position the first light relative to the first panel of the vehicle, selectively turn on and off the first light, and selectively turn on and off the second light.
Abstract:
A method for manufacturing a vehicle part, including the steps of applying a paint layer on a first face of a transparent or translucent part, applying a varnish layer on the paint layer, partially irradiating the paint layer and the varnish layer with laser radiation so as to etch the paint layer and the varnish layer, and overmolding a semi-transparent film on a second face of the transparent or translucent part opposite the first face.
Abstract:
A laminate includes a substrate; an atomic layer deposition film that is disposed on at least one surface of the substrate, and is made of an inorganic material; and a protective film that is bonded to and covers the atomic layer deposition film, and has an adhesive layer that is in contact with the atomic layer deposition film.
