| Key Features | - Can be used as a single seal - Very low moisture vapour transmission rate - Excellent application characteristics on manual and robotic equipment |
| 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. |
| Features | - Fully compliant with EN1279 - Compatible with all types of manual and robotic dispensing equipment currently available - Excellent slump resistance - Quick-setting from the molten state - Clean application with no wastage - No cleaning or purging of dispensing equipment required - Can be used as a secondary seal in conjunction with a P.I.B. primary sealant such as Bostik 2000.

| Glazing Method | Units manufactured with Bostik P5125 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. 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 P5125 Technical Bulletin and Bostik P5125 User Guide available from the Bostik Technical Service Department. |
| Important | Before embarking on any work involving Bostik P5125 Hot Melt Butyl Sealant the safety data sheet should be carefully studied by those carrying out the work. Gloves and eye protection are recommended. |
| Recommended Seal Depths | The recommended seal depths for Bostik P5125 using hollow tube spacer bar are as follows: 6 mm to 8mm sealant bonded to glass dependent on spacer bar profile. Minimum of 3 mm over the top of the spacer. It is important that a “D” shaped spacer bar profile is used rather than a “T” shaped spacer because of the ease of penetration to the shoulder back of the spacer bar. It is sometimes difficult to achieve full penetration to the shoulder back of a “T” shaped spacer resulting in air voids that could cause premature unit failure. 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. |
| Shelf Life | 2 years from date of manufacture, under the above conditions of storage. |
| Storage | Store unopened in a cool, dry place within the temperature range +5°C to +25°C. Prevent damage to the drums as denting may inhibit the function of the application equipment |
