PRODUCT DESCRIPTION
Multibond EZ-2 HV is a shelf-stable, one-component (pre-catalyzed) cross-linking polyvinyl acetate emulsion adhesive. It is a higher viscosity version of Multibond EZ-2 that has a clear glue line. Multibond EZ-2 HV is characterized by its low minimum use temperature, making it an excellent alternative for use during winter months when factory temperatures are low. With its moderately fast setting rate, viscosity stability, and high percent solids, Multibond EZ-2 HV can be used for a variety of assembly gluing applications.

APPLICATION GUIDELINES
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. Molded 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, 200-245 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 anufacturers 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.

Multibond EZ-2HV is a higher viscosity version of Multibond EZ-2. Multibond EZ-2HV is designed for edge-gluing, laminating and assembly processes in factories where temperatures may reach as low as 7 oC. While Multibond EZ-2HV may be used in radio frequency press applications, Multibond EZ-1 or EZ-1HV are better choices due to their higher handling strength immediately following the radio frequency or hot press cycle. Multibond EZ-2HV will exhibit longer assembly times than Multibond EZ-1 or EZ-1HV.
HANDLING AND STORAGE
Store in tightly closed original container. Protect from freezing. Storing at temperatures above 25ºC will reduce the maximum storage time. If thickening, separation or settling occurs, the adhesive should be thoroughly mixed and will then be ready to use again.
