Henkel and Dometic presented a new sealing solution for window frames in motorhomes, minibuses, and caravans at Henkel's new Inspiration Center Düsseldorf (ICD). This is intended to replace the butyl seals previously used.
Sealant is Applied Precisely by Robot
The window frames are sealed with a polyurethane foam gasket FERMAPOR K31 from Henkel, specially developed for this purpose, to ensure that the windows are tight against the weather.
This highly viscous and fast-curing 2K sealing foam is applied to the window frames fully automatically and very precisely using a Sonderhoff dosing machine in the FIPFG process (Formed-In-Place-Foam-Gasket) with the robot-controlled mixing head.
Offers Design Flexibility and Cost Savings
"
This allows a great deal of design freedom in the window frame design and relatively narrow and high gasket cross-sections," said Peter Fischer, senior manager market & customer activation for the Sonderhoff portfolio at Henkel.
The mixed-cell foam gasket has a good compression, so that the closing forces when installing the windows are low, and any dimensional tolerances can be compensated. In addition, the polyurethane foam gasket is more cost-effective and sustainable than a butyl seal as it reduces the overall installation time at the customers and reduces weight.
