MIXING INSTRUCTIONS
The recommended portion of catalyst to resin is five percent 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 four percent 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 should provide a uniform coverage that should cover 1/2-2/3 the length of the finger on each side. Ensure fingers are not 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.For additional questions, Franklin’s Technical Service is available.

STORAGE AND HANDLING
Shelf Life: Best if used within six months of date of manufacture. Mixing is always appropriate.
Product not available in California.
Note: Discoloration of wood veneer products occurs occasionally. This phenomenon is very infrequent and ranges in appearance, color and may vary with the species of the veneer. Discoloration may appear during or after the manufacturing process. Among other things, environmental conditions in some manufacturing plants can contribute to discoloration. If veneer discoloration occurs, our representatives are prepared to visit and assist you in attempting to identify the causes of the staining and possible solutions. Because such discoloration is attributable to conditions beyond our control, Franklin International can assume no responsibility of liability for any discolorations that might occur.
