P|8 Progress Excess moisture – for instance emitted from the wooden frame structures when temperatures increase substan- tially – must be able to diffuse through the textile. A fa- ster drying process protects the substance of the struc- ture and the heat insulating layers against moisture damage, for instance by mould growth. Any material used in the manufacture of textiles for construction pur- poses has to be able to withstand these stresses for used. They ensure a high-strength material compound which at the same time allows vapour diffusion. Adhesive: Strong partner in manufacturing The challenge which the adhesive has to master in the manufacture of these textiles, is the lamination of breathable membrane and textile fabrics, without im- pairing the diffusion to the outside. Up to four layers of different materials are laminated with adhesives, to create the compound laminate. The new PO (polyole- ® adhe- sivefamilyhaveproventobemostsuitableforthisbondi- ng process. Apart from a wide adhesion spectrum, they offer excellent long-term adhesive durability on ma- high line speeds, an output of 200 metres per minute is not uncommon. At the point where all materials to be joined are simultaneously fed from the reels into the laminator, the adhesive used needs to be compatible with the applicator system, and permit a clean appli- coating methods, the surface of these bonded sub- strates should remain as open as possible, to maintain vapour diffusion at a maximum rate. This is where the new Jowat-Toptherm® the highest compound strength with a low adhesive grammage. Additionally, high green strength and good wetting of the substrates makes production processes On site: Builder‘s needs Considering the priorities of architects and builders, term prevention of any possible damage due to wea- ther effects. They also want a vapour barrier which is still permitting adequate diffusion of moisture. If you ask Industry AAutomotive | Textile | ElectricalA
