Abstract:
The invention relates to a method for arranging particles at an interface between a soluble matrix and a matrix comprising a viscous material and particles. The method comprises the steps of: - contacting the soluble matrix and/or the matrix comprising a viscous material and particles with a support comprising at least one side, said at least one side of the support facing the soluble matrix and/or the matrix comprising a viscous material and particles, - placing the soluble matrix in contact with the matrix comprising a viscous material and particles thereby providing a structure comprising at least one interface between said soluble matrix and said matrix comprising a viscous material and particles, - subjecting the particles in said structure to an electric field and/or a magnetic field thereby forming the particles into at least one pathway of particles, said at least one pathway of particles comprising a termination at the at least one interface between the soluble matrix and the matrix comprising a viscous material and particles, and - fixating the viscous material so as to fixate the at least one pathway of particles, characterized in that said termination is exposable upon removal of the soluble matrix. The invention also relates to articles obtainable by said method, and to the use of said method in various applications.

Abstract:
The present invention relates to: a heat ray shielding adhesive which is used in bonding to a windowpane and the like and shields heat rays; a heat ray shielding transparent adhesive sheet; and a method for producing the heat ray shielding adhesive. The present invention provides a heat ray shielding transparent adhesive sheet which has high transmittance in the visible light region, low haze and more excellent transparency. [Solution] Transparency and ray shielding properties can be imparted in a simpler manner by using a heat ray shielding adhesive composition which contains fine heat ray shielding particles that have a half-value width of the first main peak of from 0.01° to 0.80° (inclusive) as determined by X-ray diffraction pattern, and a heat ray shielding transparent adhesive sheet is therefore able to be produced at low cost.

Abstract:
The present invention relates to a low VOC solvent based adhesive comprising a mixture of at least two organic solvents and a thermoplastic resin. Desirably the adhesive has a flash point of at least 100 DEG F. when measured in accordance with ASTM D3828-87. The solvent blend of the low VOC solvent based adhesive of the instant invention volatilizes at substantially reduced rates as compared to conventional solvent blends in solvent based adhesives. Furthermore, this novel low VOC solvent based adhesive is easy to apply, cost effective, and cures within a reasonable time without the use of heat, ultraviolet light or other mechanical devices. In addition, the novel low VOC solvent based adhesive has good storage stability in metal or non-metal containers.
Abstract:
Hot melt adhesives which include at least 5% of a thermoplastic elastomer block copolymer having a Vicat softening temperature of at least 60 DEG C. and a melting point of at least 100 DEG C., have improved thermal resistance properties and can be applied with conventional hot melt application equipment at temperatures of between about 149 DEG C. and about 204 DEG C. The adhesives are particularly suited to use in above-the-belt locations in automobile interiors and in furniture bonding. Especially suitable thermoplastic elastomers are polyether-polyester and polyether-polyamide segmented polymers with melting points above 149 DEG C. Hot melt adhesives based on these thermoplastic elastomers can be formulated to provide a range of properties including pressure sensitive properties and contact adhesive properties.
