Abstract:
The invention relates to a paint film comprising (a) a radiation-cured paint film which contains 40 to 90 % by weight, preferably 50 to 60 % by weight urethane acrylate, 0 to 20 % by weight, preferably 10 to 15 % by weight polyether acrylate, 10 to 50 % by weight, preferably 25 to 40 % by weight reactive diluent, 0 to 30 % by weight pigments and 0 to 10 % by weight, preferably 2 to 5 % by weight of a carboxy-functional (meth)acrylic ester, 0 to 10 % by weight of other usual paint fillers, and, in the event of curing with UV rays, 0 to 10 % by weight, preferably 3 to 6 % by weight photoinitiator, and (b) bears on one side an adhesive which has free NCO groups in the freshly spread adhesive, can be thermoplasticised, in particular in the treatment conditions provided and which has a very low surface adhesiveness.
Abstract:
A monolithic particle-containing layer in multi-layered sheeting (for example, sheeting of the type comprising resilient vinyl flooring) is produced by applying a composition comprising a suspension (17) comprising liquid carrier material (14) having dispersed therein decorative particles (13) to a surface (21) of a layer of the multi-layered sheeting, the application of the composition being preferably by the reverse roll (18, 19) coating method.
Abstract:
A method of continuously forming a coating film on a support having a large area with high productivity. The film can be an ultra-thin film having a uniform thickness. This method comprises coating continuously a coating solution having a solid content concentration of 0.05 to 40 wt.% to a support by using a gravure roll and forming a film having a dry thickness of 0.005 to 1 mu m.
Abstract:
A continuous painting method comprising the steps of forming a film of paint on a pickup roll by passing paint in a paint pan through a clearance between a doctor bar provided above the pickup roll and the pickup roll, by using a reverse roll coater; transferring a part or substantially the whole of the paint on the pickup roll on the surface of a painting roll rotating reversely with respect to the pickup roll; and then transferring a part or substantially the whole of the paint on the painting roll on the surface of a substrate board moving in a direction opposite to the direction in which the painting roll is rotated, characterized in that a metering roll (12) rotating in the same direction as the pickup roll (8) is provided close thereto to form meniscus (T) of paint between the pickup roll (8) and metering roll (12).
Abstract:
A substrate is coated with a coating material by rubbing substantially dry, discrete particles of the coating material across the surface of the substrate with a sufficient rate of energy input to cause them to adhere. Preferably, the particles are carried on the surface of a soft, resilient buffing wheel rotating sufficiently rapidly to give peripheral speeds of from 2 to 200 m/s. Exemplified coating materials include metals, metal oxides and plastics.
Abstract:
A method is proposed with which chemically defined bodies can be deposited on a substrate. Therefore, the bodies are fixed with a predetermined orientation on a stamping means which is then approached to the substrate whereby the bodies are deposited. While releasing the stamping means the bodies remain on the substrate keeping their orientation.
Abstract:
Articles such as plastics containers (1) for packaging are given a precisely-controlled band of barrier coating material (80) by a moving donor belt (4) or a rotating wheel, the material having been first applied to the belt or wheel, e.g. by a jet (12) such that excess material is removed before application to the articles. The remainder of the article can then be coated if desired by another method.
Abstract:
An application roll (5) is magnetically held against a surface medium (1) or against a mask. The material to be applied is evenly distributed over the surface of the application roll (5). Optionally, the container containing the material is movably fixed to a table.
Abstract:
A method and apparatus for coating a metallic substrate (22) with an oily substance. Use is made of a support member (30) having a ceramic coating (70) comprising an oxide ceramic material, onto which is applied the oily substance to form a film of the oily substance uniformly covering the surface of the ceramic coating (70), the film of oily substance breaking down into micro-droplets having substantially uniform size and distribution. The micro-droplets of oily substance are thereafter transferred onto a surface of the metallic substrate (22) without substantially altering the size and distribution of the micro-droplets, thereby coating the surface of the metallic substrate (22) with the oily substance. The invention is particularly useful for coating the positive electrode of a high-speed electrocoagulation printing apparatus with an olefinic substance containing a metal oxide.
Abstract:
The present invention relates to lubricant-containing pellets of thermoplastic resins, which pellets are characterized in that the lubricant is present thereon in the form of a film firmly adhering to the surface of the pellets, and to a process for their production and their use in injection molding machines.
