A composition is provided that includes aliphatic urethane acrylate; a multifunctional crosslinking agent; photoinitiator; a chemical initiator system of a peroxide or azo group containing catalyst, and a cure promoter; and a particulate filler. The composition is amenable to rapid cure to a sandable condition as compared to conventional products. By adjusting the amount of particulate filler present, a product is provided that operates as a primer, a putty, or a filler. A method of vehicle body repair includes the application of an uncured layer of the composition to the vehicle body. The uncured layer is exposed to UV radiation to induce cure of the uncured layer to form a coating in a time of between 2 and 20 minutes even with an ultraviolet wavelength emitting light emitting diode (UV LED).

A surfacing material includes a substrate having a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an electron beam radiation curable material applied to the bottom side of the substrate. The coating is an epoxy acrylic or urethane acrylic laid upon the substrate. The epoxy acrylic or urethane acrylic is irradiated with UV-radiation to produce a UV-radiation layer wherein the epoxy acrylic or urethane acrylic is neither hardened nor is an entire layer of the epoxy acrylic or urethane acrylic crosslinked but rather the epoxy acrylic or urethane acrylic is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

The present invention relates to a method for manufacturing a chromatography column, in particular for a gas phase chromatography, comprising a stationary phase made from a sol. This method comprises the following steps: (a) introducing this sol at the first end of the column, (b) moving said sol towards the second end of the column, so that a sol layer is formed on the internal wall of the column, this layer being able to form a gel on said internal wall, and (c) drying of the gel. The present invention also relates to a capillary column as well as to a microcolumn which may be manufactured according to this method.

The present invention provides a liquid crystal alignment film not only having an excellent alignment property and stability, but also having high film strength, and thus exhibiting excellent durability and a high residual image property, a method for preparing the same, and a liquid crystal display device using the same.

Transparent conductive coatings are polished using particle slurries in combination with mechanical shearing force, such as a polishing pad. Substrates having transparent conductive coatings that are too rough and/or have too much haze, such that the substrate would not produce a suitable optical device, are polished using methods described herein. The substrate may be tempered prior to, or after, polishing. The polished substrates have low haze and sufficient smoothness to make high-quality optical devices.

A method of forming a digital print on a surface (2) by applying powder of dry ink (15) including colorants (7) on the surface, bonding a part of the dry ink (15) powder to the surface (2) by a digital heating print head (80) such that the digital print is formed by the bonded dry ink colorants (7) and removing non-bonded dry ink (15) from the surface (2).

A new method capable of forming a circuit by performing metal plating on a desired portion on a substrate through a small number of steps regardless of the kind of the substrate. A method for forming a circuit on a substrate characterized in that when forming a circuit by plating on a substrate, the method includes steps of applying a coating film containing a silicone oligomer and a catalyst metal onto the substrate, and thereafter, performing an activation treatment of the catalyst metal in the coating film to make the catalyst metal exhibit autocatalytic properties, and then, performing electroless plating.

The present invention provides a liquid crystal alignment film not only having an excellent alignment property and stability, but also having high film strength, and thus exhibiting excellent durability and a high residual image property, a method for preparing the same, and a liquid crystal display device using the same.

A film forming method for forming a coating film by applying a coating solution onto a substrate having projections and recesses formed on a surface thereof by a predetermined pattern, includes: applying the coating solution onto the surface of the substrate to form a thick film having a depth of projections and recesses on a surface of the film of a predetermined value or less and having a film thickness larger than a target film thickness of the coating film; and removing the surface of the thick film to form the coating film having the target film thickness.

The present disclosure relates to polymer coatings covalently attached to the surface of a substrate and the preparation of the polymer coatings, such as poly(N-(5-azidoacetamidylpentyl)acrylamide-co-acrylamide) (PAZAM), in the formation and manipulation of substrates, such as molecular arrays and flow cells. The present disclosure also relates to methods of preparing a substrate surface by using beads coated with a covalently attached polymer, such as PAZAM, and the method of determining a nucleotide sequence of a polynucleotide attached to a substrate surface described herein.
