Abstract:
The invention relates to the use of melam deposited on a substrate, in applications requiring high humidity resistance, such as further processing comprising retort or metal deposition, or applications such as solar or display. Melam to melamine ratio (w/w) in the barrier layer is in the range from 3:1 to 50:1. The retortable laminate comprises two plastic films and in between a crystalline melam layer, the laminate having a lamination strength of about 2 N/inch or more as measured in a 90 degree tensile testing at 30 mm/min.
Abstract:
Disclosed herein is an optical article including a multilayer optical film and a primer layer disposed on the multilayer optical film. The primer layer consists essentially of a sulfopolyester and a crosslinker. The multilayer optical film may be a reflective film, a polarizer film, a reflective polarizer film, a diffuse blend reflective polarizer film, a diffuser film, a brightness enhancing film, a turning film, a mirror film, or a combination thereof. A microstructured or unstructured optical layer may be disposed on the primer layer opposite the multilayer optical film. Also disclosed herein is a method of making the optical article. Also disclosed herein is a display device including the optical article.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur selektiven Beschichtung einer Oberfläche eines Substrates mit Flüssigkeit, wobei die mit der Flüssigkeit selektiv zu beschichtende Oberfläche Bereiche mit unterschiedlichen Oberflächenenergien aufweist, und wobei vor der Benetzung ein Fluor-haltiges Plasmagas auf die Bereiche mit unterschiedlichen Oberflächenenergien unmittelbar einwirkt.
Abstract:
Coated articles may comprise one or more coating layers, including water resistant coatings. A method comprises applying such coating layers by dip, spray or flow coating. The methods can make coated containers, preferably comprising polyethylene terephthalate, from coated preforms. In some methods, the aqueous solutions, dispersions, or emulsions are substantially or completely free of VOCs.
Abstract:
A method and apparatus for applying a coating of a hot flowable adhesive to one surface of a thin flexible substrate. The adhesive is heated to above the degradation temperature of the substrate, so as to coat the substrate. The adhesive is first applied to an intermediate carrier sheet while the opposite surface of the intermediate carrier sheet is in intimate contact with a heat sink, the heat sink being cooled to a temperature substantially below the degradation temperature such that heat is conducted away from the intermediate carrier sheet so that the intermediate carrier sheet does not reach its degradation temperature and is consequently undamaged. The adhesive is then contacted to a surface of a substrate that it is desired to coat with adhesive, while said adhesive is still above the minimum bonding temperature of the adhesive. This allows the adhesive to bond to the substrate. The adhesive is then cooled and bonded to the substrate permitting later removal of the intermediate carrier sheet.
Abstract:
This invention relates to a method of coating a non-polar substrate comprising the steps of applying a primer comprising one or more silane-functional non-polar polymers on the non-polar substrate and subsequently applying one or more layers of a pigmented coating over the primer layer. In a further aspect this invention relates to a primer for a non-polar substrate.
Abstract:
A plastic pipe (1) is provided with a barrier layer (2) which is applied to its outer side and is less than 1 mu m, preferably less than 0.1 mu m, thick. The barrier layer (2) consists of metal, preferably aluminium. The metal layer (2) is applied to the plastic pipe by physical vapour deposition under high vacuum, the plastic pipe (11) being smoothed on the outer side before the layer of metal (2) is applied.
Abstract:
An article of a plastic substrate and a bond layer of a plasma polymerized cyclosiloxane having select unsaturation and a method of forming same.
Abstract:
An inventive powder composition comprises one or more than one finely divided resin chosen from a thermoplastic degradable copolyester resin containing both aliphatic and aromatic groups, a degradable UV curable polyester, a mixture of a cyclic oligomeric polyester resin, a ring opening polymerization catalyst and a degradable polyester, a degradable thermosetting polyester resin and mixtures thereof, the powder having an average particle size or diameter, as determined by laser light scattering, of from 30 to 125 µm. The composition provides thin, degradable coatings for foamed and biodegradable substrates, e.g. starch disposal articles. An apparatus for holding foam or light weight substrates comprises one or more than one perforated female pattern or jig molded in the shape of a substrate and a stand for holding said jig(s) having within it at least one enclosed chamber attached to one or more than one vacuum line, wherein the perforations in each of said jig(s) lead into said enclosed chamber. Coatings may be provided by placing a substrate in the jig, applying the powder composition to the substrate, and heating the substrate to flow out or melt said powder and to, with vacuum assistance, coalesce the melt or flow out to form a film to thoroughly coat the substrate.
