PRODUCT DESCRIPTION
Multibond Advantage 2 is a highly water-resistant, two-part crosslinking polyvinyl acetate emulsion adhesive. It is recommended for applications requiring ASTM D5572 and/or EN 204 Group D4 performance. Multibond Advantage 2 has a good catalyzed pot life and is ideal for finger jointing, edge gluing, radio frequency applications and hot pressing.
PHYSICAL PROPERTIES
APPLICATION GUIDELINES
Moisture Content: Six to eight percent is the recommended moisture content of the gluing stock. High moisture content will slow down glue line cure and cause weaker than normal adhesive bonds. Additionally, panel shrinkage may occur resulting in stress cracks or end delamination.
Stock Preparation: The preparation of the stock to be glued is extremely important. Joints cut from rip saws should be free of saw marks. They should also be straight and square. Moulded or jointed stock should be free of knife marks. Glazed or burnished joints will prevent glue penetration and should be guarded against. When possible, glue joints should be prepared and glued the same day. The stock should be machined on both top and bottom surfaces to allow even contact with radio frequency platens.
Spread: Generally, 140-245 g/m² of glue line is adequate. Lower adhesive spreads require better stock tolerances and shorter assembly times. Commonly, a mechanical glue spreader is used to apply a uniform spread to the gluing surfaces.
Pressure: Pressure is dependent upon the species or material to be glued and joint preparation. Direct contact of the gluing surfaces must be made to obtain maximum strength. Suggested pressures for various wood densities are: low 7.0-10.5 Kg/cm²; medium 8.8-12.3 Kg/cm²; high 12.3-17.6 Kg/cm². Clamps for edge gluing should be spaced 20-40 cm apart and 5 cm from the end of the panel to evenly distribute pressure along the entire length of the glue line.
RF Cure Time: Radio frequency cure times will vary from machine to machine. Machine manufacturers suggest that machines will cure about 645 cm² of glue line per minute per kilowatt. Glue joints should feel warm immediately after the cure cycle. Cure times should be determined through plant trials.
Finger Joints: Sufficient adhesive spread will provide a uniform coverage that should cover 1/2-2/3 the length of the finger on both sides in a thin continuous film. Make sure fingers aren't skipped and that the adhesive is applied to the whole joint, not just the tips of the fingers.

RELATED PRODUCTS
Advantage 310 meets or exceeds ASTM D-5751 (Edge Glue) in addition to the tests listed above. Multibond X-016 offers improved pot life and spreader stability, and lower minimum use temperature, making it a good choice for finger joint and other millwork applications. It meets or exceeds the same standards as Multibond Advantage 2. It meets European Standard DIN EN 204 D4 and European E-1 formaldehyde emission standard.
HANDLING AND STORAGE
Shelf life: Six months. Store in tightly closed original container. Protect from freezing. Storing at temperatures above 25ºC will reduce the maximum storage time. Prolonged storage will result in a gradual increase in viscosity. If thickening, separation or settling occurs, the adhesive should be thoroughly mixed and will then be ready to use again.
