Abstract:
PROBLEM TO BE SOLVED: To provide a joining optical element for use in UV region having high light transmittance in UV region and good adhesion durability in the joining state of the optical element, where the adhesive can be cured in a short time under normal temperature. SOLUTION: This joining optical element for use in UV region is formed by joining optical elements 1 and 2 which transmit UV light through an adhesive layer 3. As the adhesive layer 3, a solution in which a solvent-soluble type organic fluoropolymer with no unsaturated bond in the molecule is dissolved in a fluorine-containing solvent having ≥150°C boiling point and no unsaturated bond in the molecule is used. The solvent in a part in contact with atmosphere is vaporized and the optical element is joined in the state in which the solvent in other part is left remaining. COPYRIGHT: (C)2003,JPO
Abstract:
PURPOSE: To provide the subject adhesive comprising the combination of a main agent comprising the aqueous solution of a polymer having specific reactive groups with a curing agent comprising a specific iminated silane compound, excellent in the stability of the adhesive emulsion and in the heat resistance of the cured product, and long in the pot life. CONSTITUTION: This adhesive comprises (A) a main agent comprising the aqueous solution of a polymer having at least one kind of halogen groups, carboxyl groups and ester bonds in the molecular chain region (preferably an ethylene- vinyl acetate copolymer emulsion, an acrylic polymer emulsion), and (B) a curing agent comprising an iminated silane compound produced by blocking the primary amino group of an amino silane compound having the primary amino group with a carbonyl compound. The amino silane compound composing the component B includes a compound of the formula (A , A are 1-10C divalent linear or branched aliphatic hydrocarbon; R , R are 1-5C alkyl; m is 0-2; n is 1-3) such as aminomethyltrimethoxysilane.

Abstract:
The present disclosure relates to a copper-clad laminate that may include a copper foil layer, a fluoropolymer based adhesive layer overlying the copper foil layer, and a dielectric coating overlying the fluoropolymer based adhesive layer. The dielectric coating may include a resin matrix component, and a ceramic filler component. The ceramic filler component may include a first filler material. The dielectric coating may have an average thickness of not greater than about 20 microns.
Abstract:
Embodiments of the present disclosure pertain to adhesive compositions that include a fluorinated molecule and a hydrogen-containing molecule that are non-covalently associated with one another. The molecules may be non-covalently associated with one another through dipole-dipole interactions that create a fluorine-hydrogen electronegativity difference between at least some of the fluorine atoms of the fluorinated molecule and at least some of the hydrogen atoms of the hydrogen-containing molecule. The fluorinated molecule and the hydrogen- containing molecule may be in different phases, such as a liquid phase for one molecule and a solid phase for the other molecule. Additional embodiments pertain to methods of enhancing an adhesiveness of a surface by applying an adhesive composition of the present disclosure to the surface. Further embodiments pertain to methods of making the adhesive compositions by mixing a fluorinated molecule with a hydrogen-containing molecule such that the molecules become non-covalently associated with one another.
