摘要:
A spray booth for providing a controlled environment for spraying of material comprises a roof portion (31), a side portion which extends from the roof portion to a floor, first and second end portions which extend from respective opposing ends of the roof portion to the floor, the roof portion, side portion and first and second end portions thereby defining a work space (21) having a substantially closed side, a pair of substantially closed ends, and a substantially open side, air input equipment (34) operable to provide an input airflow into the work space via the roof portion (31), and air extraction equipment (32,37,38,33) operable to produce an output airflow to extract air from the work space. In use, the volume flow rate of the input airflow is larger than the volume flow rate of the output airflow, creating an outpour of excess of input air acting as an air curtain (23) on the open side.

To provides a process for producing a resin substrate having a hard coating layer, which is capable of forming hard coating having sufficient abrasion resistance on a resin substrate, and a resin substrate having a hard coating layer excellent in the abrasion resistance. A process for producing a resin substrate having a hard coating layer on at least one side of a resin substrate, comprising, in the following order, a step of applying a hard coating composition containing an organopolysiloxane to at least one side of the resin substrate to form a coating film of the composition, and then applying a first heat treatment to the coating film to form a cured film; an irradiation step of applying a Xe 2 excimer light irradiation treatment to the cured film in an atmosphere having an oxygen concentration of at most 5 vol%; and a step of applying an oxidation treatment to the cured film obtained by the irradiation step and then further applying a second heat treatment to form the hard coating layer.
摘要:
A method for applying a multilayer coating comprising a basecoat and a clearcoat is disclosed. The basecoat is a curable aqueous composition comprising (1) polymeric particles prepared from ethylenically unsaturated compounds including a multi-ethylenically unsaturated monomer and a keto or aldo-functional monomer, and (2) a polyhydrazide.

Die Erfindung betrifft ein Verfahren zum Herstellen eines Paneels sowie ein solches Paneel, wobei das Verfahren die Schritte umfasst: Bereitstellen einer Trägerplatte (2), Aufbringen eines Dekors auf eine Oberseite der Trägerplatte (2), Abdecken des Dekors mit einem Lackaufbau (7), welcher eine oder mehrere Lackschichten umfasst, wobei eine äußere Decklackschicht (10) zunächst mit VUV-Licht teilpolymerisiert wird, sodass eine Mikrofaltung (14) auftritt, und anschließend eine vollständige Polymerisation des Lackaufbaus (7) mittels einer Elektronenstrahlhärtung ausgeführt wird.
摘要:
The present invention relates to a process for producing a gradient low refractive index coating, comprising coating a dispersion on a surface of a substrate, the dispersion comprising an ultraviolet (UV) radiation curable material, a photoinitiator; a solvent; and a plurality of nanoparticles, providing at least a 100 part per million (ppm) oxygen atmosphere adjacent the dispersion, irradiating the dispersion with UV radiation to at least partially polymerize the UV radiation curable material, forming an insoluble polymer matrix binding the plurality of nanoparticles, and including a plurality of nanovoids, the plurality of nanovoids being filled with the dispersion depleted of the polymerizable material and the nanoparticles, wherein a first volume fraction of the plurality of nanovoids proximate the surface of the substrate is greater than a second volume fraction of the plurality of nanovoids proximate an opposing surface of the insoluble polymer matrix; and removing a major portion of the solvent from the dispersion after at least partially polymerizing the polymerizable material.
