JS680 has been specially formulated to provide a barrier to moisture and gas (inner barrier) in the design of insulating glasses using rigid spacer bars.


Application. JS680 can be applied with extrusion machines that are commonly used in the insulating glass industry at a temperature of +110°C to +130°C depending on the desired pressure and extrusion speed. Wearing gloves is recommended while handling frames to prevent any fatty materials from being deposited on the surfaces, since this could weaken adherence and even create fogging. Apply a regular and continuous strip following a minimum pre-established thickness. Compression must ensure regular and sufficient deformation of the JS680 strip. Pay particular attention to the continuity of the JS680 strip in the corners.. For full application details, please refer to our Technical Data Sheet.
