摘要:
The invention pertains to a dish support rack having outstanding resistance to chemically harsh environments, and possessing improved mechanical properties, said dish support rack comprising a metal wire frame coated with a polyamide composition [composition (C)] comprising: —more than 50% wt of a polyamide [polyamide (A), herein after], more than 50% moles of recurring units of said polyamide complying with formula: —HN—(CH2)6—NH—C(O)—(CH2)8—C(O)— [recurring units (R6,10)], and, optionally: —up to 10% wt of conventional filler(s) and/or additive(s), and to a method for its manufacture.
摘要:
An inkjet-based process for programmable deposition of thin films of a user-defined profile. Drops of a pre-cursor liquid organic material are dispensed at various locations on a substrate by a multi-jet. A superstrate that has been bowed due to a backside pressure is brought down such that a first contact of the drops is made by a front side of the superstrate thereby initiating a liquid front that spreads outward merging with the drops to form a contiguous film captured between the substrate and the superstrate. A non-equilibrium transient state of the superstrate, the contiguous film and the substrate then occurs after a duration of time. The contiguous film is then cured to crosslink it into a polymer. The superstrate is then separated from the polymer thereby leaving a polymer film on the substrate. In such a manner, non-uniform films can be formed without significant material wastage in an inexpensive manner.

Described herein are methods for producing a wear layer on a substrate comprising: applying a radiation curable composition comprising an acrylate component to a surface of a substrate; and irradiating the substrate to which said composition has been applied with a source of radiation having a wavelength from 100-280 rim, to form a wear layer. Uses of the products produced by the methods are also described herein.

Die Erfindung betrifft eine Vorrichtung zur Härtung einer auf ein Kabel (1) aufgebrachten Beschichtung, wobei die Beschichtung mindestens einen Fotoinitiator aufweist, aufweisend eine Vielzahl von UV-LEDs oder UV-LED-Packungen (2), deren emittierte Strahlung mindestens eine Wellenlänge im Bereich des Absorptionsspektrums des Fotoinitiators aufweist, wobei die UV-LEDs oder UV-LED-Packungen (2) radial so um die Längsachse eines innerhalb der Vorrichtung anordbaren Kabels (1) angeordnet sind, dass die Austrittsöffnungen der UV-LEDs radial in Richtung des Kabels (1) weisen, so dass die von den UV-LEDs emittierte Strahlung auf direktem Strahlwege auf das Kabel Wellenleiter (1) trifft.
摘要:
Apparatus for curing the coating of a workpiece (2), which comprises a tank (1) that contains an inert gas heavier than air and into which the workpiece (2) is inserted, and at least one UV-radiation source (4) situated on the exterior (E) of the tank (1) and facing at least one window (3) of the tank (1) to allow the UV radiation to pass through the window (3) towards the interior (I) of the tank (1). To prevent the interior of the tank (1) from overheating and to keep the inert gas atmosphere stable, the apparatus comprises at least one transparent filter (5) disposed between the UV-radiation source (4) and the window (3), where said transparent filter (5) is made of a material that absorbs IR radiation and is transparent to the UV radiation.
