CHARACTERISTICS:
White hot melt adhesive Hranitherm 600.31 based on EVA is suitable for gluing edges using edge-banding machined with higher feed rate. It is characterised by high thermal resistance, short open time and high strength of the bonded joint. Available also in transparent (Hranitherm 600.30) and black (Hranitherm 600.39).

PACKAGING AND STORAGE:
Keep in original container. If stored in closed containers in a cold and dry place at temperatures not exceeding 20°C, the shelf life is 24 months.
APPLICATION:
When using the hot melt adhesive, observe the application temperature and check it on a regular basis by measuring on the roller or nozzle. The temperature shown on the edge-banding machine control panel may differ from the actual temperature. Lower temperature of the adhesive may affect its open time and consequently impair the bonded joint quality. At a higher temperature, the adhesive may degrade, which affects its colour, viscosity and adhesion. When banding edges from various materials, regular testing of banding strength and quality is advisable. Recommended temperature of the environment and materials is
15–25°C.
