A volume fraction of the glass beads in the solid content is not less than 10% to not more than 35%, and a volume fraction of the lead-free low melting glass particles in the solid content is larger than a volume fraction of the low thermal expansion filler in the solid content.

Various embodiments provide a method for applying a spacer to a planar substrate, comprising supplying the spacer to be adhered to the planar substrate; defining a first notch, a second notch, and a third notch in the spacer; applying an adhesive to the spacer; translating the spacer in a longitudinal direction; aligning a first end of the spacer with a first corner of the planar substrate; feeding the spacer and the planar substrate between a front carriage and a rear carriage along a longitudinal axis of an unadhered portion of the spacer while pressing the spacer against the planar substrate to adhere a portion of the spacer being pressed by the front carriage to the planar substrate, and rotating, with a six-axis robot, the planar sheet and adhered portion of spacer.

An insulating glazing includes two glass sheets spaced apart by an air- or gas-filled cavity, a spacer arranged at a periphery of the glass sheets and that keeps the glass sheets spaced apart, a transparent spacer made of transparent plastic and placed on at least one of the sides of the glazing, and a first leaktight barrier that is leaktight to water, formed by a structural seal, a material of which is watertight, and a second leaktight barrier that is leaktight to gases and to water vapor, the leaktight barriers being made of transparent material, wherein the spacer includes on at least one of its internal and external faces, the internal and external faces being respectively facing and on the opposite side from the gas-filled cavity, a coating which is thin and constitutes the second transparent barrier, the coating and the transparent spacer forming a single assembly.

A method of adhering a substantially cured or fully cured silicone based material to a substrate surface is provided. The silicone based material is obtained by curing a condensation curable composition. The condensation curable composition comprises: (I) at least one condensation curable silyl terminated polymer having at least one hydrolysable and/or hydroxyl functional group(s) per molecule; (II) a cross-linker selected from the group of silanes having at least two hydrolysable groups per molecule; and/or silyl functional molecules having at least two silyl groups, each silyl group containing at least one hydrolysable group; and (III) a condensation catalyst selected from the group of titanates and zirconates. The method includes applying a reactive interlayer to the substrate surface and applying pressure to sandwich the reactive interlayer between a surface of the silicone based material and the substrate surface, thereby causing chemical bonding of the silicone based material to the substrate.

An object is to enable sealing of a peripheral portion of a glass panel with less effort and time. A first metal introduction device 5A is moved from one first corner A at which two sides intersect each other of a pair of rectangular glass plates, toward another end of a first side Vab of the two sides, while performing filling with a metal material. Before the metal material filling the first corner A is solidified, a second metal introduction device 5B is moved from the first corner A toward another end of another second side Vad, while performing filling with a metal material. After the first side Vab and the second side Vad are filled with the metal material, both glass plates are rotated by 180 degrees, and the first metal introduction device 5A is moved toward another end of a fourth side Vcd of two sides intersecting each other at a second corner C diagonal to the first corner A, while performing filling with a metal material. Before the metal material filling the second corner C is solidified, the second metal introduction device 5B is moved from the second corner C toward another end of another third side Vbc, while performing filling with a metal material.

A single axis application unit for processing a glass workpiece includes a workpiece supporting table, an applicator movable on a traveler shiftable along a first linear axis and a central suction unit that is activateable to grip the glass workpiece that travels along a second linear axis oriented generally perpendicular to the first linear axis. A central suction unit brake selectively secures the central suction unit both rotationally and translationally. The central suction unit is freely moveable both translationally and rotationally when the central suction unit brake is released. A mid-peripheral suction unit is located at a fixed location remote from the central suction unit and selectively activateable to grip the glass workpiece to hold the glass workpiece in a fixed orientation. A corner suction gripper is movable with the applicator parallel to the first linear axis, and is selectively activateable to grip the glass workpiece.

There is provided a gas trapping material and vacuum heat insulation equipment where the gas trapping material can be activated in a sealing step of the vacuum heat insulation equipment, and production efficiency can be enhanced by maintaining a high gas trapping characteristic even when a gas is released in a baking step or in a sealing step under an air atmosphere. The gas trapping material contains porous metal oxide and silver particles having an average particle size of 0.5 nm to 100 nm inclusive.

Embodiments herein relate to window spacer assemblies including surfaces with relatively high surface energy. In an embodiment, a window spacer assembly is included.
