JOINLEADER 868 2-Component Silicone IG Sealantis particularly suitable as a secondary edge sealant for the manufacture of multipane insulating glass used in structural glazing façades.
JOINLEADER 868 2-Component Silicone IG Sealant is also used for sealing and bonding in building construction and technical/industrial applications.
REQUIRED TESTING IN THE APPLICATION
It is the responsibility of the end user to thoroughly test any proposed use of the sealant and independently conclude satisfactory performance in the application.
Components A and B of JOINLEADER 868 each have a shelf life of at least 12 months. If stored in tightly closed original containers in a dry place at temperatures not exceeding 27°C, the “best used before end” date of each lot is shown on the product label. If the material is kept beyond the recommended shelf life, it is not necessarily unusable, but a quality control should be performed on the properties relevant to the application.
