In the building construction sector thermoplastic hot-melt powders are mostly used for roofing constructions / roofing films. Next to this main application adhesive powders are also used in insulation materials, floor covering or wall and ceiling elements.

A flat bed press for the lamination after the scatter head allows the best results for heat sensitive substrates.
