Pattex White Line Construction Foam is a white polyurethane foam for filling, cushioning, insulating, and sealing joints and cavities. Thanks to its fine, homogeneous cell structure, it is suitable for use in window frames, pipe penetrations, roller shutter boxes, openings in roof structures, and other wall penetrations, among other applications. It can also be used to seal shaft and well rings. The foam is also intended for installing wooden or plastic door frames; the door panel may weigh up to 20 kg.
According to Pattex, WhiteTeq Quattro technology produces four times as many cells per unit volume as conventional PU foams. This results in a thermal conductivity of approximately 0.032 W/mK and sound insulation of more than 63 dB at a layer thickness of 20 mm. The foam also has a flexibility of 25%. This is particularly helpful for joint seals, where the cured foam not only fills the gap but also provides insulation. The white color is less noticeable on light-colored components and surfaces than standard yellowish PU foams.
You can use the assembly foam on nearly all absorbent and non-absorbent surfaces; exceptions include PE, PP, and PTFE. The surface must be solid, clean, and free of dust and grease. Before use, shake the can about 20 times and apply it with the valve pointing downward. The foam expands by about 150% as it cures—therefore, joints do not need to be completely filled with fresh foam. When installing door frames, for example, filling the gap by about 50% is recommended.
After about 10 to 15 minutes, the surface is tack-free; after about 75 minutes, the foam can be cut. Once fully cured, it is dimensionally stable and can be plastered over, painted over, or covered with adhesive. According to the manufacturer, a 500-ml can yields about 19 liters of foam.
