PRODUCT DESCRIPTION
Advantage® 415 is a highly water-resistant, 2-part crosslinking polyvinyl acetate emulsion adhesive with a low minimum use temperature. When mixed with Aluminum Chloride (Catalyst A) the product surpasses both ASTM D 5572 wet use finger joint and ASTM D 5751 wet use edge glue standard. These standards are the basis for Hallmark Certification. Advantage 415 can be used for finger jointing, edge gluing, hot pressing, and radio frequency gluing. Advantage 415 is the longest open time product in our Advantage line. Like all adhesives, proper gluing practices are needed to achieve stated performance.
PHYSICAL PROPERTIES
MIXING INSTRUCTIONS
The recommended portion of catalyst to resin is 5% by volume (one quart to five gallons). A reduced portion can be used under certain conditions such as burning in a radio frequency press, but water resistance performance should be validated. Mixes containing less than 4 % by volume should be avoided. Place the resin in mixer and slowly add catalyst under agitation. Continue mixing for five minutes after the catalyst addition to ensure a uniform mixture.
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, 35-50 pounds per 1,000 square feet of glue line (6-9 wet mils or 180-260 ft²/gal) is adequate. Extruding this glue onto the substrate is a common method of application. Glue pot pressure will range from 20-70 psi depending on extrusion head port size.
Pressure: Pressure is dependent upon the species or material to be glued. Direct contact of the gluing surfaces must be achieved to obtain maximum strength. Suggested pressures for various substrates are; high pressure laminates 30-80 psi; solid core stock 100-150 psi; all veneer constructions 100-250 psi.
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.
RF Cure Time: Radio frequency cure times will vary from machine to machine. Machine manufacturers suggest that machines will cure between 75 and 100 square inches 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.

Mixing is always appropriate.
Product not sold into California.
Note: Discoloration and checking of wood veneer products occurs occasionally. These occurrences are infrequent and range in appearance, color and may vary with the species of the veneer. Discoloration and checking may appear during or after the manufacturing process. Among other things, environmental conditions in some manufacturing plants and end-use locations can contribute to checking. If veneer discoloration or checking occurs, our representatives are prepared to visit and assist you in attempting to identify the causes and possible solutions. Because such discoloration and checking are attributable to conditions beyond our control, Franklin International can assume no responsibility or liability for any problems that might occur.
