SEALOMELT HOT MELT BUTYL

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 gun nozzle whilst gunning sealant.

Further advice can be obtained from the 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, in order 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.
