Description General purpose hot melt adhesive for straight edge banding - for bonding melamine edgings, paper, plastic laminate, wood veneer, ABS and PVC to chipboard, MDF or wood panels 727 IS CHARACTERIZED BY: Low viscosity, long open time Suitable as well for medium-low speed automatic edge banding machines High adhesion to a wide range of materials Above characteristics make the adhesive especially suitable for Use in quick melt equipment Use on working lines operating at a speed from 15 m/min up to 40 m/min Bonding on the same working line of edgings of different nature CHARACTERISTICS Composition : EVA copolymers, synthetic resins, inert fillers Shape : granules Colours : natural, nut TECHNICAL DATA Softening point (Ring & Ball) : 98°- 103°C. Brookfield Viscosity at 210°C : 60000 - 70000 mPa.s APPLICATION Recommended machine speed: should be at least 15 m/min. High working speed influences favourably bond results. at least 15 m/min. Application temperature: 200-210°C on to the roller spreader; temperature into the melting tank should be such as to ensure the correct temperature on to the roller when the working line is running. This condition is usually reached at a temperature in the range 170°-190°C, depending on the type of melting tank. 727 is characterized by an excellent melt stability. During work breaks, anyhow, it is recommended to reduce temperature in the melting tank and on to the roller under 160°C, to prevent thermo-oxidative degradation and the need of having recourse too often to cleaning of spreader unit.
