BOSTIK P5125

Hot melt sealant
SDS All Documents
Product overview
Bostik P5125 Hot Melt Butyl Sealant has been specifically formulated for use in the production of insulating glass units. Bostik P5125 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 P5125 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.

Applications

For more detailed application details please refer to the Bostik P5125 user guide. 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.
