Description de l'application
Placage de chants avec colles thermofusibles
Depuis des dizaines d’années le collage de chants sur des panneaux à base de bois avec des matériaux divers et variés a été une pratique commune. Les exigences en termes d’aspect visuel, les progrès technologiques, et également l’immense et pratiquement illimitée diversité des matières utilisables, tous ces facteurs sont des challenges particuliers pour la colle. Pour l’industrie de l’ameublement actuelle, la perfection des chants est devenue un critère fondamental d’évaluation de la qualité de l’ensemble du meuble fabriqué, l’utilisateur final exigeant en effet que la ligne de colle soit quasiment invisible et parfaite.
Les adhésifs réactifs modernes, thermoplastiques et durcissant à l'humidité garantissent une adhésion supérieure et une finition de haute qualité pour la pose des bandes de chant. Un large spectre d'adhésion sur différents matériaux de bande de chant est tout aussi important que le réglage rapide de l'adhésif pour un traitement direct en aval, une résistance à la chaleur et une durabilité élevées. Les adhésifs thermofusibles PUR sont réputés pour répondre aux exigences les plus strictes en matière d'apparence sans trait de colle, ainsi que de résistance à la chaleur, à l'humidité et aux produits chimiques dans les cuisines et les salles de bains. Jowat propose ces adhésifs thermofusibles de dernière génération également sous forme de granulés. Leur facilité de traitement les rend particulièrement attractifs pour les processeurs qui n'ont pas utilisé la technologie PUR auparavant. Les thermofusibles Jowat constituent ainsi la solution idéale pour toutes les applications de plaquage de chants.

Directions for use
PUR hot melt adhesives can be processed on throughfeed lines at different feed speeds, as well as on roller and nozzle applicators. All parts of the melting and application units coming into contact with the adhesive should have a non-stick coating to prevent possible catalytic reactions due to metal contact. A non-stick coating will also facilitate a considerably easier cleaning.
The melting and application units should be equipped with a precise temperature control to prevent local overheating and unwanted secondary reactions. Heating the adhesive to a temperature above the recommended processing temperature will usually lead to a fast increase in viscosity of the melt due to a so-called thermal crosslinking reaction in the adhesive (the allophanate reaction), which is triggered by heat and does not need moisture.
Cleaning
If necessary, flush out hot melt remnants from the melt and applicator units with flushing agent Jowat® 930.94 (red). Crosslinked, solid material has to be dissolved with cleaner Jowat® 930.60 (please test for suitability before use).
