Therefore ensure correct temperature! Delivery form: granules Colours available: ivory-20 Identification: not required according to the German hazardous substances regulations GefStoffV (see our safety data sheet) Attention: When hot melt adhesives are melted and applied, vapours are set free and an unpleasant odour can occur, even if the recommended working temperature has been observed. Moreover if the prescribed working temperature is exceeded over a longer period, harmful decomposition products can develop. Precautions should be taken to eliminate the vapours, e.g. by using a suitable ventilation system. Application devices • Automatic edge banding machines with roller application • Automatic edge bonding machines with sword nozzle application Application techniques The substrates for edge banding must be processed at exactly right angles and must be free from dust. Boards as well as edge materials have to be acclimatised to room temperature. The most favourable moisture content of the wood is 8-10%. The room temperature must not be lower than 18° C. Draught has to be avoided. Temperature control: Regularly check the temperature directly at the application system by means of a laboratory thermometer, a bimetal thermometer or by a thermometer with electric contacts. Readjust it, if necessary. The thermometers installed in the machine may give incorrect readings after extended use. Line feed: 20-40m/min. Higher speeds only after own testing. Application quantity: The quantity to be applied should be adjusted in such a manner as to slightly show on the edge of the part to be glued. In order to check whether the adhesive film is continuously applied, a strip of transparent rigid PVC can be used.
