- Advantages
Advantages of gun grade polyurethane foam compared to hand held foam:
• very precise application contributes to less foam being used;
• easier handling and work;
• no leakage or dripping from the gun’s nozzle;
• less cleaning required;
• swift replacement of cans.

- Uses
It is used in construction industry for sealing, filling, insulating, fixing and mounting (of doors, windows, blinds etc.). Greater volume allows you to do more with just one can, which means you have to replace cans less frequently. This makes the job less time consuming and contributes to less waste packaging. Tekapur Mega XXL gun grade is a one-component polyurethane foam hardening by air humidity. The final volume of the foam once hardened is up to 70l, which is by 50% more than with standard gun grade polyurethane foam
- Application
Surfaces should be clean, free of dust, grease and other impurities. Dry and porous surfaces should be moistened with water. The optimal temperature of can at work is room temperature. At lower temperature put the can into warm water with max. temperature of 40°C for about 20 minutes. Before use shake can thoroughly with the valve upside down. Than screw the can onto the gun and press the trigger for about 2 seconds so that the gun is filled with foam. During foam application hold the gun in vertical position. Apply pressure on the trigger to allow the outflow of the foam. The output of the foam can be regulated with the adjustment screw on the back side of the gun. When replacing the can, shake the new can vigorously, unscrew the empty can and immediately replace it with a new one. The can replacement has to be fast to prevent the foam to harden in the adapter. Hardened foam residues in front of the nozzle can be removed only mechanically. At short work interruptions the can can be left screwed onto the gun, but screw on the back side of the gun must be tightened. The can must be under pressure and at least half full, otherwise the foam will harden in the gun. At longer work interruptions, clean the gun with the Tekapur cleaner. Please note that the foam would expand 30–50%. If you are filling a gap wider than 5cm, work in layers. Apply the second layer once the first one has hardened. You can speed up the process of hardening by spraying the foam with water. Once hardened, foam should be protected against UV light. Once the foam has hardened, cut it with a sharp knife and finish with plastering, sealing, covering, painting etc. If you do not use the entire can clean the valve with the TEKAPUR cleaner. Hardened foam can only be removed mechanically.

•Aerosol can of 840ml, 560ml
• Other packagings are available by agreement
Storage & Handling
- Storage
18 months (from +5°C to +25°C) or at lower temperatures for shorter periods of time (e.g. during transport). Higher temperatures shorten storage life. Store the cans in an upright position.
