    Technical Details & Test Data

    Processing Information

    Processing

    For the bonding of genuine leather, artificial leather and spacer fabrics a double side adhesive application on the laminate and on the carrier is necessary to achieve the maximum bonding performance. For foil applications a single side adhesive application on the carrier is sufficient. Equipment, containers, hoses, etc. which come into contact with Thermonex® 073-05A white must be of corrosion resistant material (i.e. stainless steel 1.4541 or 1.4571 or plastic) to avoid coagulation. Any contact with non-ferrous metals (like hoses, sealing rings, filter bodies, etc.) must be avoided in any case. The adhesive can be applied by spraying out of a pressure pot or with automated mixing systems. The use of HVLP spray guns minimizes overspray. Also roller coating is possible as an application system.

    Drying

    The recommended maximum drying temperature can be found in the technical data section. Drying with dry air (< 10 % rel. humidity) leads to a faster and very gentle drying process. During the drying process, the humidity in the drying channel increases strongly. The excessive moisture content must be reduced either by fresh air supply or by drying out physically. Caution: The drying time is influenced by the absorbency of the surface, drying temperature, coating weight, air humidity etc. and needs to be checked under real life conditions.
