BOSTIK 5000

Hot melt insulating glass sealant

Uses

Bostik 5000 Hot Melt Butyl Sealant has been specifically formulated for use in the production of insulating glass units. Bostik 5000 Hot Melt Butyl Sealant is a single part butyl rubber based sealant which, when applied at the correct temperature, sets quickly from its molten state allowing units to be moved from their assembly location between two and five minutes after application. Units can therefore be sealed and glazed within the same day. Bostik 5000 Hot Melt Butyl Sealant has a high output and fast heat loss enabling optimum turn round of unit production. The combination of these properties also means that corner defects can be easily avoided thereby ensuring a complete seal around the unit.

Application

Surface Preparation 
Bostik 5000 Hot Melt Butyl Sealant exhibits excellent adhesion to cut, ground or polished glass, aluminium and galvanised steels spacer  bar. It is essential that all surfaces are clean and dry and free from foreign matter. Coated glasses which require edge deleting must be used inaccordance with manufacturer's instructions.
 
Application
The sealant should be applied by means of a suitable heated dispenser. lt 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 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. lf 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. lf the units are to be stored on a rack ensure that they are adequately supported under both panes of glass.
 
Glazing Method 
Units manufactured with Bostik 5000 Hot Melt Butyl should be glazed in accordance with the current G.G.F.(Glass and Glazing  Federation) methods or other G.G.F. recognised and approved methods. 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. lf 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. Furthered detailed information can be obtained from the relevant Bostik Hot Melt Butyl Sealant Technical Bulletin from the Bostik Technical Service Department.
