WebWith PVA’s Atmospheric Bonding process complex multi axis curvatures are able to be optically bonding with LOCA (Liquid Optically Clear Adhesive) The use of optical contact bonding allows the production of a final product with properties as good as the bulk solid. This can include temperature and chemical resistances, spectral absorption properties and reduced contamination from bonding materials. See more Optical contact bonding is a glueless process whereby two closely conformal surfaces are joined together, being held purely by intermolecular forces. See more Intermolecular forces such as Van der Waals forces, hydrogen bonds, and dipole-dipole interactions are typically not sufficiently strong to hold two apparently conformal rigid bodies together, since the forces drop off rapidly with distance, and the actual area in … See more Since the method requires no binder, balsam or glue, the physical properties of the bound object are the same as the objects joined. Typically, glues and binders are more heat … See more • Adhesion – Molecular property • Cohesion (chemistry) – Chemical property of like molecules sticking together See more Isaac Newton has been credited with the first description of conformal interaction observed through the interference phenomenon known as Newton's rings, though it was S. D. Poisson in 1823 who first described the optical characteristics of two identical … See more In addition to both surfaces' being practically conformal (in practice often completely flat), the surfaces must also be extremely clean and free from any small contamination that … See more Originally the process was confined to optical equipment such as prisms—the earliest examples being made around 1900. Later the range of use was expanded to microelectronics and other miniaturised devices. See more

WebUnter Optical Bonding versteht man das Verkleben verschiedener Komponenten mit einem klaren Klebstoff. Dieses Verfahren eliminiert den Luftspalt zwischen Glas und Display. Die Vorteile: bessere Lesbarkeit, keine störenden Reflektionen, ausgezeichnete Bildqualität. Je nach Einsatzgebiet stehen verschiedene Verfahren zur Verfügung. WebOptically Clear epoxy Adhesives. Optical clear epoxy adhesive is a pure UV curing adhesive. It has good adhesion to different kinds of substrates, lower shrinkage, high thermal resistance comparing with Acrylic clear adhesives. Optical clear epoxy adhesives are widely used in optical market for lens bonding.
