Abstract:
A method for coating a surface of an electrically non-conductive substrate with powder coatings, the method comprising the following steps: providing a substrate to be coated, pre-heating the substrate to be coated to a temperature of 40 to 140° C. in order to decrease the surface resistance of the substrate to less than 1012 ohms, preferably to within the range of 1010 to less than 1012 ohms, electrostatically coating the surface with powder coating in a single layer, which powder coating comprises a reactive system which, in particular, cures into a thermoset, curing the powder coating layer at a temperature of 170° C. or less.
Abstract:
Rapidly curable electrically conductive clear coatings are applied to substrates. The electrically conductive clear coating includes to clear layer having a resinous binder with ultrafine non-stoichiometric tungsten oxide particles dispersed therein. The clear coating may be rapidly cured by subjecting the coating to infrared radiation that heats the tungsten oxide particles and surrounding resinous binder. Localized heating increases the temperature of the coating to thereby thermally cure the coating, while avoiding unwanted heating of the underlying substrate.
Abstract:
A system and a method for providing a film having a matte finish is described. A coatable material is applied to a substrate. The viscosity of the coatable material is changed and a face-side roller contacts the coatable material to impart a matte finish thereon; and hardening the coatable material.
Abstract:
A machine can include a conveyor that receives and conveys a circuit assembly treated with a UV curable coating material; a UV zone that includes LED-based UV radiation sources; a circuit assembly sensor; a heating zone; and a controller that controls power to at least one of the LED-based UV radiation sources based at least in part on information from the circuit assembly sensor.
Abstract:
A method and an arrangement are disclosed for producing an electrically conductive pattern on a surface. Electrically conductive solid particles are transferred onto an area of predetermined form on a surface of a substrate. The electrically conductive solid particles are heated to a temperature that is higher than a characteristic melting point of the electrically conductive solid particles, thus creating a melt. The melt is pressed against the substrate in a nip, wherein a surface temperature of a portion of the nip that comes against the melt is lower than said characteristic melting point.
Abstract:
A prepreg for manufacturing a fibre-reinforced composite material, the prepreg including a body having a layer of fibrous reinforcement impregnated with a matrix resin material, and a powder coating layer of resin material on at least one major surface of the body and at least partly fused to the matrix resin material
Abstract:
A monitoring device includes a light source, an optical filter, and an optical detector. The monitoring device may monitor curing processes, such as ultraviolet (UV) curing processes to determine the progression of the level of cure of a light-activated material to a substrate. The light source emits light toward a light-activated material, such as a film, and/or a substrate. The optical filter is positioned so that a wavelength of the light is transmitted through the optical filter after the light is reflected off of the substrate and/or the film. The optical detector is positioned to detect the light that is transmitted through the optical filter.
Abstract:
Disclosed is a paint film which has excellent heat-radiating properties which comprises an undercoat paint film layer which contains from 1 to 20 mass % with respect to the total solid fraction of the paint film of carbon black and a top-coat paint film layer which contains 1 to 40 mass % with respect to the total solid fraction of the paint film of a pearl pigment and which does not contain aluminum powder and the paint film thickness of the top-coat paint film layer is from 11 to 50 μm.
Abstract:
A method for accelerated drying of at least one polymer which is located at least partially on a component, in particular at least a layer of paint and/or a sealing agent which is applied to an aircraft component in particular with a different material composition, involving the following steps of: a) at least partially applying the at least one polymer, in particular an epoxy resin and/or polyurethane-based layer of paint and/or a sealing agent, to an upper side of the component, and b) at least partially drying the polymer by means of electromagnetic radiation with a wavelength range of between 0.28 μm and 4.0 μm. Accelerated drying of the polymer, in particular the paint layer thereby becomes possible from an upper side of the component to an upper side of the paint layer.
