The sealant should be applied by means of a suitable heated dispenser. It is very important that the sealant is applied within the recommended temperature range; therefore it is advisable that the application temperature be checked daily with a digital thermometer at the applicator nozzle whilst applying sealant.

Further advice can be obtained from the Bostik Technical Service Department. The sealant should be applied into the cavity of the insulating glass unit in such a manner that complete wetting of the glass and spacer occurs. If an internal locating nozzle is used, the nozzle should be checked regularly to avoid excessive wear, in order to ensure that the correct seal depth is maintained. Care should be taken on sealing each corner and the sealant should be pressed together whilst still molten by means of a silicone rubber pad, or other method. This is to prevent any holes or gaps in the sealant at the corners, which could lead to premature unit failure. If the units are to be stored on a rack, ensure that they are adequately supported under both panes of glass.

Units manufactured with Bostik Sealomelt Xtra should be glazed in accordance with the current G.G.F. (Glass and Glazing Federation) methods or other G.G.F. recognized and approved methods (UK) or FGIA (IGCC) Glazing Guidelines (US).

Further information may be obtained from the Bostik Technical Service Department. The use of adhesive tape is not recommended to cover the edge of the unit. Drained and ventilated systems should be used where possible otherwise fully bedded glazing methods are necessary. If the unit is to be glazed using a glazing compound which is likely to be in contact with the edge seal of the unit, then it is important to ensure its compatibility with the Hot Melt Sealant BEFORE glazing. Further detailed information can be obtained from the Bostik Sealomelt Xtra Technical Bulletin and Bostik Sealomelt Xtra User Guide available from the Bostik Technical Service Department.
