4. Coltogum Universal foam
Application area
For clean and controlled backfilling and foaming of connection joints, wall openings, and cavities such as roller shutter or blind boxes, as well as roof extensions and roof insulation. Door frames and window frames are easily filled and foamed, glued, and sealed. In the case of interior doors, the joint between the door lining and the masonry must be fully filled with foam. Excellent properties for insulating cold/heat bridges and for sound insulation. The PU foam adheres to almost all building materials and can be left open with dense top coats (UV protection) of commercially available paint and varnish systems or additionally plastered or pasted over.
Application notes
Only apply to clean, grease-free, and stable surfaces. 1C polyurethane foam requires additional moisture (water) for curing; dry and absorbent substrates must be well moistened beforehand.

7. Coltogum Gun foam
Ready to use, moisture-curing gun foam based on polyurethane. This single-component system features TÜV-tested, guaranteed non-stick safety valves.
It is ideal for inserting window frames and door frames, as well as for filling, insulating, gluing, and foaming. It is particularly useful where bridging, bonding, and insulation are required, such as in window construction, for clean and controlled backfilling, and for insulating sealing of connection joints in windows and roller shutter boxes. It can also be used for filling the connection joints of external door frames, but not for pure installation purposes without additional mechanical fastening. Additionally, it is suitable for foaming out small wall openings and other cavities.
With adhesion to almost all substrates, this gun foam allows for universal use. It adheres to all common building materials, except polyethylene, silicone, oils and greases, mould release agents, or similar substances. The cured foam is semi-hard, predominantly closed-cell, rot-proof, and resistant to moisture and temperature from -40°C to +80°C (short-term up to +100°C). It is resistant to aging, but not to UV radiation.
